Figure 13: 1RC0457, 1RC0459 Roof Curb Dimensions

DuctworkDuctwork should be designed and sized accordingto the methods in Manual D of the Air ConditioningContractors of America (ACCA) or as recommendedby any other recognized authority such as ASHRAEor SMACNA.A closed return duct system should be used. Thiswill not preclude use of economizers or outdoorfresh air intake. The supply and return air ductconnections at the unit should be made with flexiblejoints to minimize noise.The supply and return air duct systems shouldbe designed for the CFM and static pressurerequirements of the job. They should NOT be sizedto match the dimensions of the duct connections onthe unit.Refer to Figure 11 and Figure 12 for bottom and sideair duct openings.

Duct CoversUnits are shipped with the side duct openingscovered and a covering over the bottom of the unit.For bottom duct application, ZL Models requirea filler plate to be removed from the return airopening, for all other models no other changes arenecessary. For side duct application, remove theside duct covers and install over the bottom ductopenings. The panels removed from the side ductconnections are designed to be reused by securingeach panel to its respective bottom duct opening.But keep in mind that the supply and return panelsare installed with the painted surface DOWN,facing the bottom duct opening. The gasket mustbe removed from the insulation side of the ductcover so it is not directly exposed to the heatingelements. The panels are secured by sliding theminto slots in the back of the duct openings andscrewing them to the base of the unit with screws(Use screws removed from original panel location.).Seals around duct openings must be tight.



CAUTION

When fastening ductwork to side duct flanges on unit,insert screws through duct flanges only. DO NOT in-sert screws through casing. Outdoor ductwork mustbe insulated and water-proofed.

Condensate DrainA side condensate drain is provided to facilitatecondensate piping. A condensate drain connectionis available through the base pan for piping insidethe roof curb. Trap the connection per Figure 17.The trap and drain lines should be protected fromfreezing.Plumbing must conform to local codes. Use asealing compound on male pipe threads. Installcondensate drain line from the 3/4 inch NPT femaleconnection on the unit to an open drain.

Figure 17: Condensate Drain

CompressorsThe compressor used in this product is specificallydesigned to operate with R-410A Refrigerant andcannot be interchanged.

CAUTION

This system uses R-410A Refrigerant which operatesat higher pressures than R-22. No other refrigerantmay be used in this system.

The compressor also uses a refrigerant oil that isextremely hygroscopic, meaning it absorbs waterreadily. They can absorb 15 times as much water asother oils designed for HCFC and CFC refrigerants.Take all necessary precautions to avoid exposure ofthe oil to the atmosphere.

CAUTION

Do not leave the system open to the atmosphere. Unitdamage could occur due to moisture being absorbedby the refrigerant in the system. This type of oil ishighly susceptible to moisture absorption.

R-410A compressor lubricants are known to causelong term damage to some synthetic roofingmaterials.

CAUTION

Exposure, even if immediately cleaned up, may causeembrittlement (leading to cracking) to occur in oneyear or more. When performing any service that mayrisk exposure of compressor oil to the roof, take pre-cautions to protect roofing.

Procedures which risk oil leakage include, but arenot limited to, compressor replacement, repairingrefrigerant leaks, replacing refrigerant componentssuch as filter drier, pressure switch, metering deviceor coil.Units are shipped with compressor mountingswhich are factory-adjusted and ready for operation.

CAUTION

Do not loosen compressor mounting bolts.

FiltersTwo-inch filters are supplied with each unit. Four-inch filters may be used with no modification to thefilter racks. Filters must always be installed ahead ofevaporator coil and must be kept clean or replacedwith same size and type. Dirty filters reduce thecapacity of the unit and result in frosted coils orsafety shutdown. Refer to physical data tables, forthe number and size of filters needed for the unit.The unit should not be operated without filtersproperly installed.

Power And Control WiringField wiring to the unit, fuses, and disconnects mustconform to provisions of National Electrical Code(NEC), ANSI/NFPA No. 70 – Latest Edition (in U.S.A.),current Canadian Electrical Code C221, and/or local



ordinances. The unit must be electrically groundedin accordance with NEC and CEC as specified aboveand/or local codes.Voltage tolerances which must be maintained at thecompressor terminals during starting and runningconditions are indicated on the unit Rating Plate andTable 1.

CAUTION

208/230-3-60 and 208/230-1-60 units control trans-formers are factory wired for 230v. Change tap ontransformer for 208v operation. See unit wiring dia-gram.

The internal wiring harnesses furnished with thisunit are an integral part of the design certifiedunit. Field alteration to comply with electrical codesshould not be required. If any of the wire suppliedwith the unit must be replaced, replacement wiremust be of the type shown on the wiring diagramand the same minimum gauge as the replaced wire.A disconnect must be utilized for these units.Factory installed disconnects are available. Ifinstalling a disconnect (field supplied), refer toFigure 11 thru Figure 12 for the recommendedmounting location.

CAUTION

Avoid damage to internal components if drilling holesfor disconnect mounting.

Note: Since not all local codes allow themounting of a disconnect on the unit, pleaseconfirm compliance with local code beforemounting a disconnect on the unit.

Electrical line must be sized properly to carry theload. USE COPPER CONDUCTORS ONLY. Each unitmust be wired with a separate branch circuit feddirectly from the meter panel and properly fused.

CAUTION

When connecting electrical power and control wiringto the unit, water-proof connectors must be used sothat water or moisture cannot be drawn into the unitduring normal operation. The above water-proofingconditions will also apply when installing a field sup-plied disconnect switch.

CAUTION

When installing equipment in a facility with a 3 phasehigh-leg delta power supply, care must be taken toensure that the high-leg conductor is not attachedto either of the two legs of the (single phase, directdrive) X13 or ECM motors. Failure to do so can re-sult in the motor acting erratically or not running atall.Check for the high leg conductor by checking volt-age of each phase to ground.Example: A or L1 phaseto ground, voltage reading is 120V. B or L2 phase toground, voltage reading is 195 to 208V. C or L3 phaseto ground, voltage reading is 120V. Therefore B orL2 phase is the high Leg.

Optional Gas HeatThese gas-fired heaters have aluminized-steel oroptional stainless steel, tubular heat exchangerswith spark ignition.

Gas PipingProper sizing of gas piping depends on the cubicfeet per hour of gas flow required, specific gravityof the gas and the length of run. "National FuelGas Code" Z223.1 (in U.S.A.) or the current GasInstallation Codes CSA-B149.1 (in Canada) shouldbe followed in all cases unless superseded by localcodes or gas utility requirements. Refer to the PipeSizing Table 21. The heating value of the gas maydiffer with locality. The value should be checkedwith the local gas utility.

Figure 20: Side Entry Gas Piping

Note: Routing of gas piping must not interferewith the flue or heat compartment access.

Gas ConnectionThe gas supply line can be routed within the spaceand roof curb, exiting through the unit’s basepan.Refer to Figure 11 thru Figure 12 for the gas pipinginlet location. Typical supply piping arrangementsare shown in Figure 20. All pipe nipples, fittings, andthe gas cock are field supplied.Gas piping recommendations:

1. A drip leg and a ground joint union must beinstalled in the gas piping.

2. Where required by local codes, a manual shut-off valve must be installed outside of the unit.

3. Use wrought iron or steel pipe for all gas lines.Pipe dope should be applied sparingly to malethreads only. If local codes allow the use of aflexible gas appliance connector, always use anew listed connector. Do not use a connectorwhich has previously serviced another gasappliance.



WARNING

Natural gas may contain some propane. Propane isan excellent solvent and will quickly dissolve whitelead and most standard commercial compounds. Aspecial pipe dope must be used when assemblingwrought iron or steel pipe. Shellac based compoundssuch as Gaskolac or Stalastic, and compounds suchas Rectorseal #5, Clydes’s or John Crane may beused.

4. All piping should be cleaned of dirt and scaleby hammering on the outside of the pipe andblowing out loose particles. Before initial start-up, be sure that all gas lines external to the unithave been purged of air.

5. The gas supply should be a separate line andinstalled in accordance with all safety codes asprescribed under Limitations.

6. A 1/8-inch NPT plugged tapping, accessiblefor test gauge connection, must be installedimmediately upstream of the gas supplyconnection to the unit.

7. After the gas connections have beencompleted, open the main shut-off valveadmitting normal gas pressure to the mains.Check all joints for leaks with soap solution orother material suitable for the purpose. NEVERUSE A FLAME.

WARNING


Failure to follow the safety warning exactly could re-sult in serious injury, death or property damage.Nevertest for gas leaks with an open flame. Use a commer-cially available soap solution made specifically for thedetection of leaks to check all connections. A fire orexplosion may result causing property damage, per-sonal injury or loss of life.

CAUTION

The furnace and its individual shut-off valve must bedisconnected from the gas supply piping system dur-ing any pressure testing at pressures in excess of 1/2PSIG. Pressures greater than 1/2 PSIG will cause gasvalve damage resulting in a hazardous condition. If itis subjected to a pressure greater than 1/2 PSIG, thegas valve must be replaced. The furnace must be iso-lated from the gas supply piping system by closing itsindividual manual shut-off valve during any pressuretesting of the gas supply piping system at test pres-sures equal to or less than 1/2 PSIG.

WARNING

Threaded joints should be coated with a sealing com-pound that is resistant to the action of liquefied petro-leum gases. Do not use Teflon tape.

Check all connections for leaks when piping iscompleted using a soap solution. NEVER USE AFLAME.

Fieldinstalled Economizer accessories include completeinstructions for installation.There are two Economizer options. Each is specificto footprint and unit voltage:

1. Vertical Flow application with barometric reliefstandard.

2. Horizontal Flow application with barometricrelief standard.

Power ExhaustThe Power Exhaust is a field installed accessory.Field installed Power Exhaust accessories includecomplete instructions for installation.The Power Exhaust factory installed option is forDown Flow application only.There are two field installed Power Exhaustaccessories:

1. Down Flow application.

2. Horizontal Flow application that requires thepurchase of a barometric relief hood.

Rain HoodAll of the hood components, including the misteliminators, the gasketing and the hardware forassembling, are packaged and located betweenthe condenser coil section and the main unitcabinet, if the unit has factory installed options.If field installed accessories are being installed allparts necessary for the installation comes in theaccessory.

Blower PhasingZL units are properly phased at the factory. Checkfor proper blower rotation. If the blower rotatesin the wrong direction at start-up, the electricalconnection to the unit is misphased. Change thephasing of the Field Line Connection at thefactory or field supplied disconnect to obtainproper rotation.

Blower RotationCheck for proper supply air blower rotation. If theblower is rotating backwards, the line voltage at theunit point of power connection is misphased (SeeBlower Phasing).Table 23: Supply Air Limitations

Belt TensionThe tension on the belt should be adjusted asshown in Figure 23.

Figure 23: Belt Adjustment

CAUTION

Procedure for adjusting best tension below:

1. Loosen the three nuts (A and B on side and Con back) of motor mount slide plate. See Figure23.

2. Adjust tension by placing a flat heat screwdriverinto the belt tightening slots (1/4 in. X 1/2 in.)in the motor mount slide plate and applyingpressure against the motor mounting plate. SeeFigure 23.

3. Tighten the three loosened nuts (A, B, and C).

4. Determine the deflection distance fromnormal position, use a straight edge fromsheave to sheave as reference line. Use belttension checker to apply a perpendicular forceto the belt at the midpoint of the span asshown. Deflection distance of 4mm (5/32 in.) isobtained

5. After adjustments are completed re-tightennuts (A, B, and C).

Altitude and Temperature Correction forCFM, Static Pressure and Power.The information below should be used to assistin application of product when being applied ataltitudes at or exceeding 1000 feet above sea level.The air flow rates listed in the standard blowerperformance tables are based on standard air at sealevel. As the altitude or temperature increases, thedensity of air decreases. In order to use the indoorblower tables for high altitude applications, certaincorrections are necessary.A centrifugal fan is a "constant volume" device. Thismeans that, if the rpm remains constant, the CFMdelivered is the same regardless of the density ofthe air. However, since the air at high altitude is lessdense, less static pressure will be generated andless power will be required than a similar applicationat sea level. Air density correction factors are shownin Table 24 and Figure 24.

Figure 24: Altitude/Temperature Correction Factors

The examples below will assist in determining theairflow performance of the product at altitude.Example 1: What are the corrected CFM, staticpressure, and BHP at an elevation of 5,000 ft. if theairflow performance data is 3,000 CFM, 1.4 IWC and2.0 BHP?Solution: At an elevation of 5,000 ft. the indoorblower will still deliver 3,000 CFM if the rpm isunchanged. However, the Altitude correction mustbe used to determine the static pressure andBHP. Since no temperature data is given, we willassume an Air Temperature of 70°F. The Altitude/Temperature Factors show the correction factor tobe 0.832.Corrected static pressure = 1.4 x 0.832 = 1.16 IWCCorrected BHP = 2.0 x 0.832 = 1.66Example 2: A system, located at 5,000 feet ofelevation, is to deliver 3,000 CFM at a static pressureof 1.4 in. Use the unit blower tables to select theblower speed and the BHP requirement.Solution: As in the example above, no temperatureinformation is given so 70°F is assumed.The 1.4 in. static pressure given is at an elevationof 5,000 ft. The first step is to convert this staticpressure to equivalent sea level conditions.Sea level static pressure = 1.4 in. / .832 = 1.68 in.

Enter the Supply Air Blower Performance Table at3,000 CFM and static pressure of 1.68 in. The rpmlisted will be the same rpm needed at 5,000 ft.Suppose that the corresponding BHP listed inthe table is 2.0. This value must be corrected forelevation.BHP at 5,000 ft. = 2.0 x .832 = 1.66Drive Selection

1. Determine side or bottom supply ductApplication.

2. Determine desired airflow.

3. Calculate or measure the amount of externalstatic pressure.

- Add or deduct any additional staticresistance from Table 39.

4. Using the operating point determined fromsteps 1, 2, and 3, locate this point on theappropriate supply air blower performancetable. (Linear interpolation may be necessary.)

5. Noting the RPM and BHP from step 4, locate theappropriate motor and, or drive.



6. Review the BHP compared to the motor optionsavailable. Select the appropriate motor and, ordrive.

7. Review the RPM range for the motor optionsavailable. Select the appropriate drive ifmultiple drives are available for the chosenmotor.

8. Determine turns open to obtain the desiredoperation point.

Example

1. 3400 CFM

2. 1.6 iwg

3. Using the airflow performance table below, thefollowing data point was located: 1039 RPM and2.52 BHP.

4. Using the RPM selection table below, Model ZLand Size 08 (Tons) 7.5 is found.

5. 2.59 BHP exceeds the maximum continuousBHP rating of the 1.5 HP motor. The 3 HP motoris required.

6. 1039 RPM is within the range of the 3 HP drives.

7. Using the 3 HP motor and drive, 1.5 turns openwill achieve 1039 RPM.

1 Add these values to the available static resistance in the respective Blower Performance Tables.2 Deduct these values from the available external static pressure shown in the respective Blower Performance Tables.3 The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return

air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.

Supply Air Drive Adjustment

CAUTION

Before making any blower speed changes reviewthe installation for any installation errors, leaks orundesirable systems effects that can result in lossof airflow.Even small changes in blower speed canresult in substantial changes in static pressure andBHP. BHP and AMP draw of the blower motor will in-crease by the cube of the blower speed. Static pres-sure will increase by the square of the blower speed.Only qualified personnel should make blower speedchanges, strictly adhering to the fan laws.

At unit start-up, the measured CFM may be higheror lower than the required CFM. To achieve therequired CFM, the speed of the drive may haveadjusted by changing the datum diameter (DD) ofthe variable pitch motor sheave as described below:

Use the following tables and the DD calculated perthe above equation to adjust the motor variablepitch sheave.EXAMPLE NEW DATUM DIAMETERA 4 ton unit was selected to deliver 1,600 CFM with a1VL34 motor sheave, but the unit is delivering 1,350CFM. The variable pitch motor sheave is set at 4turns open.Use the equation to determine the required DD forthe new motor sheave,

Use Table 38 to locate the DD nearest to 2.48 in.Close the sheave to 2 turn open.

EXAMPLE NEW BHP

= (Speed increase)3 • Original BHP = New BHP

= (Speed increase)3 • BHP at 1,350 CFMEXAMPLE NEW MOTOR AMPS

= (Speed increase)3 • Original Amps = New Amps

= (Speed increase)3 • Amps at 1,350 CFMTable 38: Motor Sheave Datum Diameters

CAUTION

Belt drive blower systems MUST be adjusted to thespecific static and CFM requirements for the applica-tion. The Belt drive blowers are NOT set at the facto-ry for any specific static or CFM. Adjustments of theblower speed and belt tension are REQUIRED. Veri-fy proper sheave alignment; tighten blower pulley andmotor sheave set screws after these adjustments. Re-checking set screws and belt tension after 10-12 hrs.run time is recommended.

1 Add these values to the available static resistance in the respective Blower Performance Tables.2 Deduct these values from the available external static pressure shown in the respective Blower Performance Tables.3 The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return

air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.

1 We strongly recommend 3-wire (for FC bus) and 4-wire, 2twisted-pair (for SA bus), 22 AWG stranded, shielded cable.A 22 gauge cable offers the best performance for variousbaud rates, cable distances, and number of trunk devicesprimarily due to lower conductor-to-conductor capacitance.Shielded cable offers better overall electrical noise immunitythan non-shielded cable. Observe the shield groundingrequirements.

2 We recommend 26 AWG solid, 6-wire (3 twisted pairs)cable as the best fit for fabricating modular cables with themodular jack housing assembly. Be sure the cable you usefits the modular jack housing. The preassembled cables thatare available from Anixter (Part No. CBL-NETWORKxxx) use24 gauge wire.

Operation

Cooling Operation• A Y1 call for the first stage of cooling is passed

to the unit control board (UCB). The UCB thendetermines whether the requested operationis available and if so, which components toenergize. With a Y1 call for first stage cooling, theUCB determines if a first stage cooling output isvalid as long as all safeties and time-delays allowa C1 output for cooling. The C1 relay on the UCBcloses and sends 24 volts to the M1 relay. Thisstarts compressor #1 on low and also energizesM4 for the condenser fan(s) to run at nominalspeed. The UCB energizes the VFD-equippedblower at the first stage speed as set in the SmartEquipment™.

• If a Y2 call is present, it is passed to theUCB. The UCB then determines whether therequested operation is available and if so, whichcomponents to energize. With a Y2 call for secondstage cooling, the UCB determines if a secondstage cooling output is valid as long as all safetiesand time-delays allow a C2 output for cooling. TheC2 relay on the UCB closes and sends 24 volts tothe M2 to the M2 relay which starts compressor#2 on high speed. The UCB energizes the VFD-equipped blower at the second stage speed as setin the Smart Equipment™ control.

• If a Y3 call is present, it is passed to theUCB. The UCB then determines whether therequested operation is available and if so, whichcomponents to energize. With a Y3 call for thirdstage cooling, the UCB determines if a third stagecooling output is valid as long as all safeties andtime-delays allow a C3 output for cooling. TheC3 relay on the 4-stage board closes and sends24 volts to terminal block TB3 which energizescompressor #1 on high speed. The UCB energizesthe VFD-equipped blower at the third stage speedas set in the Smart Equipment™ control.



Free cooling operation witheconomizer• With a demand for first stage cooling either from

a thermostat or space sensor and the outsideair is suitable for free cooling, the dampers aremodulated to maintain supply air temperature towithin +/- 1 degree of the free cooling SAT uppersetpoint. If the output to the economizer actuatoris at 10 VDC and the supply air temperaturecannot be controlled to within 5 degrees of thefree cooling SAT upper setpoint, one compressoris energized. The economizer is then modulatedto maintain supply air temperature to within +/- 1degree of the free cooling SAT upper setpoint.

• If a demand for second stage cooling occurs andthe economizer is already modulating to maintainthe supply air temperature to the cooling SATupper setpoint, the setpoint is changed to thefree cooling SAT lower setpoint. Any compressorsthat are energized remain energized and theeconomizer dampers are modulated to maintainsupply air temperature to within +/- 1 degreeof the cooling SAT lower setpoint. If the outputto the economizer actuator is at 10 VDC and thesupply air temperature cannot be controlledto within 5 degrees of the cooling SAT lowersetpoint, compressor stage 2 is energized. Theeconomizer is then modulated to maintain supplyair temperature to within +/- 1 degree of thecooling SAT lower setpoint.

• If the output to the economizer actuator is atminimum position and the supply air temperaturedrops more than 5 degrees below the currenteconomizer SAT setpoint, the highest stagecompressor is de-energized as long as theminimum run time has elapsed.

Economizer with single enthalpysensorWhen the room thermostat calls for cooling, thelow voltage control circuit from R to G and Y1 iscompleted. The UCB energizes the blower motor(if the fan switch on the room thermostat is set toAUTO position) and drives the economizer dampersfrom fully closed to their minimum position. If theenthalpy of the outdoor air is below the setpoint ofthe enthalpy controller (previously determined), Y1energizes the economizer. The dampers modulateto maintain a constant supply air temperatureas monitored by the discharge air sensor. If theoutdoor air enthalpy is above the setpoint, Y1

energizes the compressor and condenser fan motoronly.When the thermostat has been satisfied, it de-energizes Y1. If the compressor has satisfied itsminimum run time, the compressor and condenserfan are de-energized. Otherwise, the unit operatesthe cooling system until the minimum run timesfor the compressor are completed. After thecompressor de-energizes, the blower is stoppedfollowing the elapse of the fan off delay for cooling,and the economizer damper goes to the closedposition. If the unit continues fan operation, theeconomizer damper goes to the min. position.

Economizer with dual enthalpysensorsThe operation with the dual enthalpy sensors isidentical to the single sensor except that a secondenthalpy sensor is mounted in the return air. Thisreturn air sensor allows the economizer to choosebetween outdoor air and return air, whichever hasthe lowest enthalpy value, to provide maximumoperating efficiency.

Economizer with power exhaustA unit equipped with an economizer (single ordual enthalpy) and a power exhaust operatesas specified above with one addition. The powerexhaust motor is energized 45 seconds after theactuator position exceeds the exhaust fan setpointon the economizer control. The R to G connectionprovides minimum position but does not providepower exhaust operation.

Motorized outdoor air dampersThis system operation is the same as the units withno outdoor air options with one exception. Whenthe R to G circuit is complete, the motorized damperdrives open to a position set by the thumbwheelon the damper motor. When the R to G circuit isopened, the damper spring returns fully closed.Each cooling system is monitored for operationoutside of the intended parameters. Errors arehandled as described below. All system errorsoverride minimum run times for compressors.

High-pressure limit switchDuring cooling operation, if a high-pressure limitswitch opens, the UCB de-energizes the compressor,initiates the ASCD (anti-short cycle delay), and stopsthe condenser fans. If the call for cooling is stillpresent at the conclusion of the ASCD, the UCB re-energizes the halted compressor.If a high-pressure switch opens three times withintwo hours of operation, the UCB locks out thecompressor.

Low-pressure limit switchThe low-pressure limit switch is not monitoredduring the initial 30 seconds of a cooling system'soperation. For the following 30 seconds, the UCBmonitors the low-pressure switch to ensure thatit closes. If the low-pressure switch fails to closeafter the 30-second monitoring phase, the UCB de-energizes the compressor, initiates the ASCD, andstops the condenser fans.When the low-pressure switch is proven (closedduring the 30-second monitor period describedabove), the UCB monitors the low-pressure limitswitch for any openings. If the low-pressure switchopens for greater than 5 seconds, the UCB de-energizes the compressor, initiates the ASCD, andstops the condenser fans.If the call for cooling is still present at the conclusionof the ASCD, the UCB re-energizes the haltedcompressor.If a low-pressure switch opens three times withinone hour of operation, the UCB locks out thecompressor.

Evaporator low limitThe evaporator low limit sensor (EC1) is locatedon the suction line at the evaporator coil. Duringcooling operation, if the evaporator low limit sensordetects a temperature below 26°F (default), the UCBde-energizes the compressor, initiates the ASCD,and stops the condenser fans. If the call for coolingis still present at the conclusion of the ASCD, theUCB re-energizes the halted compressor.If the UCB detects the evaporator low limit sensor(EC1) falling below 26°F (default) three times within

two hours of operation, the UCB locks out thecompressor.

Low ambient coolingTo determine when to operate in low ambientmode, the UCB has an outdoor air temperaturesensor (OAT) with a low ambient setpoint at45ºF (default). When the OAT sensor senses atemperature below the low ambient setpointand the thermostat is calling for cooling, the UCBoperates in the low ambient mode.Low ambient mode operates the compressors inthis manner: 10 minutes on, 5 minutes off. Theindoor blower is operated throughout the cycle.The 5-minute off period is necessary to defrost theindoor coil.Low ambient mode always begins with compressoroperation. Compressor minimum run time mayextend the minutes of compressor operation. Theoff cycle begins immediately following the elapse ofthe minimum run time.When operating in low ambient mode, anevaporator low limit sensor (EC1) temperaturebelow 26ºF de-energizes the compressor. If thecall for cooling is still present at the end of theASCD and the evaporator temperature sensor(EC1) temperature is above 26°F, the unit resumesoperation.

Safety controlsThe unit control board monitors the following inputsfor each cooling system:

1. An evaporator low limit sensor (EC1) to protectagainst low evaporator temperatures due toa low airflow or a low return air temperature,set at 26°F. The evaporator low limit sensor islocated on the suction line at the evaporatorcoil.

2. A high-pressure switch to protect againstexcessive discharge pressures due to a blockedcondenser coil or a condenser motor failure.The switch opens at 625 ± 25 psig.

3. A low-pressure switch to protect against loss ofrefrigerant charge. the switch opens at opensat 50 ± 5 psig.

The above pressure switches are hard-solderedto the unit. The refrigeration systems areindependently monitored and controlled. On anyfault, only the associated system is affected by anysafety or preventive action.



The UCB monitors the temperature limit switch ofelectric heat units and the temperature limit switchand the gas valve of gas furnace units.

Compressor protectionIn addition to the external pressure switches,the compressors also have inherent (internal)protection. If there is an abnormal temperature risein a compressor, the protector opens to shut downthe compressor. The UCB incorporates featuresto minimize compressor wear and damage. Ananti-short cycle delay (ASCD) is used to preventoperation of a compressor too soon after itsprevious run. Additionally, a minimum run time isimposed any time a compressor is energized.The ASCD is initiated on unit start-up and on anycompressor reset or lock-out.

Gas Heating Operation1. Heating stages are controlled by the W1

through W2 thermostat inputs. A W1 or W2input energizes a H1 or H1/H2 output.

2. When the pre-ignition process is complete theignition module energizes the gas valve andprovides a 24 V input to the MV terminal on theUCB.

3. The FAN ON HEAT DELAY timer starts as soonas 24 V is present on MV terminal. When thetimer expires the FAN output for the indoorfan operation energizes. If 24 V is not receivedon the MV terminal within 6 minutes, analarm appears and the fan output energizesimmediately and remains On until the alarmclears.

4. When the thermostat heat inputs are lost andthe 120 second Minimum Heat Run Timers haveexpired, heating outputs stage off. The FAN OFFHEAT DELAY timer starts when 24 V is removedfrom the MV terminal. When the timer expires,the FAN output for the indoor fan operation de-energizes.

Note: If 24 V is lost on the MV terminalduring the same heat cycle, an alarmappears and the fan output energizes andremains On until 24 V is present again onthe MV terminal.

Note: If 24 V is present on the MV terminalwithout a call for heat, an alarm appearsand the fan output energizes. If thiscondition occurs for 6 minutes an alarmappears, and remains, until the alarmcondition is cleared.

5. At any time, if 24 V is lost on the LIMIT terminal,the FAN output for indoor fan operation isenergized. If 24 V is lost on the LIMIT input 3times in 1 hour, an alarm appears and the FANoutput is energized. The heating H1 and H2outputs are de-energized until the alarm iscleared.

Gas Heat Ignition Control BoardFunction

Ignition Control Board on StandbyThe Ignition Control Board (ICB) has all outputs de-energized and monitors the thermostat and flamesense. The ICB resets ignition trial and flame losscounters. The ICB begins a call for heat when W1 isenergized at the Unit Control Board (UCB). The ICBignores W2 until ignition has been established.

Call for heatThe ICB checks to see if the pressure switch is open.If the pressure switch is closed, the ICB flashes "3"on the LED and waits indefinitely for it to open.When the pressure switch is sensed as open, the ICBbegins pressure switch proving period. If the call forheat is lost, the ICB goes back to Standby.

Pressure switch provingThe ICB energizes the induced draft motor andwaits for the low pressure switch to close. When thelow pressure switch closes, the control begins Pre-purge period. If the call for heat is lost, the controlde-energizes the inducer without post-purge andreturns to standby.If the low pressure switch does not close within 10seconds of inducer energizing, the control flashes"2" on the LED. If the pressure switch does not closewithin 5 minutes of inducer energizing, the controlshuts off the inducer for 30 seconds, then energizesthe inducer for another 5 minute try to close thepressure switch. This cycle continues indefinitelyuntil either the pressure switch is proved closed, orthe call for heat ends.



Pre-purgeThe ICB monitors the low pressure switch andensures it remains closed during pre-purge. If thepressure switch opens, the control goes back topressure switch proving mode. The control waitsfor a 15 second pre-purge period, then begins theignition trial.

Ignition trial periodThe ICB energizes the main gas valve, second stagegas valve and spark outputs for a 10 second Ignitiontrial. The control de-energizes the spark when flameis sensed and enters a flame stabilization period.If flame is not established within the ignition trialperiod, the control de-energizes the spark and gasvalve and checks for maximum number of ignitiontrials. The ICB has a maximum number of 3 ignitiontrials. If the control has attempted the maximumnumber of ignition trials within the same call forheat without flame, the control will lockout flashing"4" on the LED. If the control has attempted lessthan maximum ignition trials, it begins an inter-purge period before attempting another ignitiontrial.If the call for heat is lost during an ignition trialperiod, the control immediately de-energizesspark and gas. The control runs the inducer motorthrough a post purge period before de-energizing.If the pressure switch is lost during an ignition trialperiod, the control immediately de-energizes sparkand gas. The control begins pressure switch provingbefore an inter-purge and re-ignition attempt.

Flame stabilization periodIf a flame is detected during the Ignition TrialPeriod, the ICB then enters the flame stabilizationperiod. If a flame is not detected in 2 seconds, themain valve is de-energized and a retry operationbegins. The flame stabilization period lasts 10seconds. flame detection must be lost for 2 secondsduring flame stabilization for the main valve to bede-energized. When the flame stabilization periodhas ended, a loss of flame detection for 3/4 secondswill result in the main valve being de-energized.If flame is lost during the flame stabilization period,the control counts it as a flame loss and retriesignition or locks out as described in Low heatsection.

Main Burner operationHigh heat warm-upTwo stage models run high heat for the first30 seconds following flame stabilization period

regardless of W2 demand. If W2 is not energizedat the end of this 30 second period the control de-energizes the high gas output. If W2 is energizedthe control remains on high heat.Low heatThe ICB keeps the main gas valve and induced draftmotor energized while continuously monitoring thecall for heat, low pressure switch, and flame status.If the call for heat (W1) is lost, the control de-energizes the gas valve and begins post purge.If low pressure switch opens, the control de-energizes the gas valve and begins pressure switchproving mode.If flame is lost, the control de-energizes the gasvalve within 2.0 seconds and counts the flame loss.If flame has been lost more than 5 times within thesame call for heat, the control locks out flashing "5"on the LED. If flame has been lost less than 5 times,the control attempts re-ignition after a 30 secondinter-purge period.High heatThe ICB recognizes a call for 2nd stage heat whenW2 is energized. The control energizes the high gasoutput.If the call for 2nd stage heat goes away and the 1ststage call remains, the control de-energizes the highgas valve and returns to low heat operation.Response to loss of W1, low pressure switch, andflame are identical to low heat operation.

Post PurgeThe ICB runs the induced draft motor for a 5 secondpost-purge period, then de-energizes the inducer. Ifa call for heat occurs during post-purge, the controlfinishes the post-purge, drops inducer out to re-prove open pressure switch before continuing withthe heat cycle.

LockoutWhile in lockout, the ICB keeps the main gas valveand induced draft motor de-energized.Lockouts due to failed ignition or flame losses maybe reset by removing the call for heat (W1) formore than 1 second, but less than 20 seconds, orby removing power from the control for over 0.25seconds. The control will automatically reset lockoutafter 60 minutes.Lockouts due to detected internal control faults willreset after 60 minutes or power interruption.



High temperature limit switchIf the high temperature limit switch is open thecontrol will run the inducer, de-energize the gasvalve, and flash "6" on the LED. When the hightemperature switch closes, the control will restartthe ignition sequence beginning with pre-purge.If the high temperature limit is open for more than6 minutes continuously during a call for heat, it isassumed that the main blower has failed and thecontrol shall enter a hard lockout and flash a "9"on the LED. During the hard lockout, the controlwill continue to run the inducer as long as the limitswitch is open. If the limit switch recloses in thishard lockout condition, the inducer will run a postpurge and then shutoff. The control shall remainlocked out until power is removed and shall notreset automatically.

Roll-out switchIf the roll-out switch opens for more than 0.25seconds, the ICB will run the inducer for a post-purge period, immediately de-energize the gasvalve, and flash "7" on the LED.If the roll-out switch closes, the control shall remainlocked out until power removed or "W" is removed.Rollout switch lockout shall not reset automatically.

Power interruptionsPower interruptions less than 0.80 seconds shallnot cause the ICB to interrupt the heat sequence.Power interruptions over 0.250 seconds will causethe control reset lockout and ignition trial counters.Power interruptions of any duration shall notcause lockout or any operation requiring manualintervention.

Flame present with Gas offIf flame is sensed for longer than 2.0 seconds duringa period when the gas valve should be closed, theICB will enter lockout. The control will turn on theinducer blower while the flame is present.

Welded gas valve relay responseIf either or both Main and 2nd Stage Gas valveoutputs are sensed to be off for more than 1 secondwhen commanded to be ON the ICB shuts off alloutputs and enters lockout.If the Main valve output is sensed to be energizedfor more than 1 second when commanded to be off,the control de-energizes the induced draft motor(if flame is not present) to attempt to open thepressure switch to de-energize the gas valve. If theMain gas valve is still sensed as energized after the

inducer has been off for 15 seconds, the controlre-energizes the inducer to attempt to vent theunburned gas. In either case, the control locks out.

2. Turn on the furnace and make sure thethermostat is calling for Second stage (100%input) heat.

3. Measure the time needed for one revolution ofthe hand on the lowest increment dial on themeter. A typical gas meter has a 1/2 or a 1 cubicfoot test dial.

4. Using the number of seconds it takes for onerevolution of the dial, calculate the cubic feet ofgas consumed per hour. (See example below).

5. If necessary, adjust the high pressure regulatoras discussed in the section Manifold GasPressure Adjustment. Be sure not to over-firethe furnace on second stage. If in doubt, it isbetter to leave the second stage of the furnaceslightly under-fired. Repeat Steps 1-5.

To determine the rate of gas flow (FirstStage)

6. Turn off all other gas appliances connected tothe gas meter.

7. Turn on the furnace and make sure thethermostat is calling for first stage heat.

8. Even when the thermostat is calling for firststage heat, the unit will light on second stageand will run on second stage for 1 minute.Allow this one-minute time period to expire andbe certain the unit is running on first stage.

9. Measure the time needed for one revolution ofthe hand on the lowest increment dial on themeter. A typical gas meter has a 1/2 or a 1 cubicfoot test dial.

10. Using the number of seconds it takes for onerevolution of the dial, calculate the cubic feet ofgas consumed per hour (See example below).

11. If necessary, adjust the low pressure regulatoras discussed in the section Manifold GasPressure Adjustment. Be sure not to under-fire the furnace on first stage. If in doubt, itis better to leave the first stage of the furnaceslightly over-fired (Refer to Table 42 for inputvalue). Repeat Steps 1-6.

Note: To find the Btu input, multiply thenumber of cubic feet of gas consumedper hour by the Btu content of the gas inyour particular locality (contact your gascompany for this information as it varieswidely from area to area).

EXAMPLEBy actual measurement, it takes 19 seconds for thehand on a 1 cubic foot dial to make a revolutionwith a 200,000 Btuh furnace running. To determinerotations per minute, divide 60 by 19 = 3.16. Tocalculate rotations per hour, multiply 3.16 • 60 =189.6. Multiply 189.6 • 1 (0.5 if using a 1/2 cubic footdial) = 189.6. Multiply 189.6 • (the Btu rating of thegas). For this example, assume the gas has a Bturating of 1050 Btu/ft3. The result of 199,000 Btuh iswithin 2% of the 200,000 Btuh rating of the furnace.



Manifold Gas Pressure Adjustment

Two StageThis gas furnace has two heat stages. Therefore, thegas valve has two adjustment screws located undertwo cover screws. The second stage adjustmentscrew is adjacent to the "HI" marking on the valveand the first stage adjustment screw is locatedadjacent to the "LO" marking on the valve (SeeFigure 27).Manifold pressure adjustment procedure.Adjust second stage (Refer to Table 42 for inputvalue) pressure first, then adjust first stage (Refer toTable 43 for input value) pressure.

1. Turn off all power to the unit.

2. Using the outlet pressure port on the gas valve,connect a manometer to monitor the manifoldpressure.

3. Remove cover screws covering HI and LOpressure adjustment screws.

4. Turn on power to the unit.

5. Set thermostat to call for second stage heat andstart furnace.

6. If necessary, using a screwdriver, turnthesecond stage adjustment screw (adjacentto the “HI” marking on the valve) clockwise toincrease manifold pressure or counterclockwiseto decrease manifold pressure.

7. After the high manifold pressure has beenchecked, adjust the thermostat to call for firststage heat.

8. If necessary, using a screwdriver, turn the firststage adjustment screw (adjacent to the “LO”marking on the valve) clockwise to increasemanifold pressure or counterclockwise todecrease manifold pressure.

9. Once pressure has been checked, replace thecover screws covering the HI and LO pressureadjustment screws.

Adjustment Of Temperature RiseThe temperature rise (the difference of temperaturebetween the return air and the heated air from thefurnace) must lie within the range shown on the unitrating plate and the data in Physical Data.After the temperature rise has been determined, theCFM can be calculated as follows:

After about 20 minutes of operation, determine thefurnace temperature rise. Take readings of boththe return air and the heated air in the ducts (about6 feet from the furnace) where they will not beaffected by radiant heat. Increase the blower CFM todecrease the temperature rise; decrease the blowerCFM to increase the rise (See SUPPLY AIR DRIVEADJUSTMENT).

Note: Each gas heat exchanger size has aminimum allowable CFM. Below this CFM, thelimit will open.

Burners/Orifices Inspection/ServicingBefore checking or changing burners or orifices,CLOSE MAIN MANUAL SHUT-OFF VALVE AND SHUTOFF ALL POWER TO THE UNIT.

1. Open the union fitting just upstream of theunit gas valve and downstream from the mainmanual shut-off valve in the gas supply line.

2. Remove the screws holding each end of themanifold to the manifold supports.



3. Disconnect wiring to the gas valve. Remove themanifold & gas valve assembly. Orifices cannow be inspected and/or replaced.

To service burners, complete step 4.

4. Remove the heat shield on top of the manifoldsupports. Burners are now accessible forinspection and/or replacement.

Note: Reverse the above procedure toreplace the assemblies.

Make sure that burners are level and seat at the rearof the gas orifice.
