The Meridian Basic control system converts a singlezone HVAC unit into a variable air volume/variableair temperature multiple zone system. The micro-processor based Zone Manager calculates theheating and cooling requirements for each zonebased on real time information received from eachZone Controller. The Zone Manager then directs theHVAC unit to provide the appropriate amount ofheating, cooling, and ventilation to satisfy eachzone's requirements. A static pressure sensor, whichmodulates a bypass damper, maintains a constantsystem duct pressure.
Substantial savings can be realized using the Me-ridian Basic system instead of installing multipleHVAC units to accommodate multiple zones. TheMeridian Basic system is versatile and can be usedwith any 3-40 ton HVAC unit. It controls a variety ofterminal units including single duct pressure de-pendent or pressure independent zone damper.
User friendly, menu driven, fill in the blank pro-gramming, makes the Meridian Basic easy to set upand operate without the need for specialized training.
MeridianView, a Windows based color graphic soft-ware package is available at no additional charge.The optional CommLink II must be ordered andconnected to a PC in order to use the software foron-site control and monitoring.

The Meridian 2ZMO004700224 and the2ZMO004700324 Basic Zone Managers aremicroprocessor based HVAC unit controllers.The 2ZMO004700224 is the Fahrenheit ver-sion and the 2ZMO004700324 is the Celsiusversionn. The Zone Manager calculates theheating and cooling requirements for eachzone based on real time information receivedfrom the Zone Controllers. It then controls theHVAC unit to provide the appropriate amountof heating, cooling, and ventilation to satisfyeach zones requirements. The Zone Manageralso controls a bypass damper which modu-lates the bypass airflow at the HVAC unit, inorder to maintain proper duct static pressure.One Zone Manager is required for each multi-ple zoned HVAC unit that is to be part of thebuilding HVAC system. Each Zone Managercan accommodate up to 16 zones.
The Zone Manager keypad & display provide acentral operators interface to all controllers onthe network. All system variables, setpoints,and values can be viewed and modified fromone convenient location. Menu driven pro-gramming makes the Meridian Basic systemeasy to set up and operate. The Zone Man-ager is password protected to prevent unau-thorized access to the system.
The Zone Manager is designed to be mountedindoors on a flat surface. Typically, the Zone Manager is mounted on a wall in the building managers office, orlocated on the wall of an equipment room or other location that prevents access by unauthorized personnel.

Because the zones in a Meridian Systemare controlled using variable air volume, it isunlikely that all zones will be at design loadat the same time. This zoning allows forload diversity to be taken into account whensizing the central HVAC unit. This typicallywill provide better comfort with a smallerHVAC unit than with the use of a constantvolume system. Use a load program to de-termine the individual zone loads. Becauseof zone diversity the HVAC unit should besized for the correct instantaneous peakload, not the sum of the peak loads aswould be the case when sizing a normalconstant volume unit system. The BypassDamper should be sized to provide for themaximum amount of air to be bypassed inthe system. This is typically 60 to 70% ofthe HVAC units rated capacity. These cal-culations will be used in selecting the ap-propriate Bypass Damper Size(s).
The Meridian Systems utilize a typical lowpressure duct design. To reduce noiseproblems, duct pressures should not ex-ceed 1” W.C..
Using the maximum acceptable velocity fora bypass duct (typically 1750-2250 FPM forminimal noise), find the smallest damperthat will deliver the required CFM as deter-mined by the load program.

When determining the bypass duct size, be sure to take into ac-count any transition fittings and their associated pressure drops.Locate the bypass duct velocity used in the duct design program inthe left hand column of the Bypass Damper Selection Data table.Move across the table and find the Bypass Damper size which willprovide the acceptable CFM to meet the bypass airflow require-ments.
Compare the Bypass Air Damper size selectedagainst the bypass duct size to determine if the nextsize up or down will provide acceptable performancewithout requiring a transition fitting.
Up to a maximum of two additional Bypass Dampers may beslaved together with the main Bypass Damper for large bypassairflow requirements. This design should be reserved only forsituations when it is not practical to use a single large BypassDamper. The slaved valves should all be of the same size forproper control. Divide the total CFM by two or three depending onhow many bypass and slave dampers you will be using and sizeaccordingly.

DescriptionThe 2ZMD00470xxxx series Pressure De-pendent Zone Damper for Fahrenheit op-eration consists of a round air damper,zone controller, and actuator. An optionalauxiliary relay board (2ZRE0047000024) isavailable for control of auxiliary heat and/orcontrol of series or parallel flow fan terminalunits.
The Zone Controller (2ZC0047000024) ismicroprocessor based and communicateswith the Zone Manager on the Meridiannetwork communications loop. The ZoneController monitors the space temperatureand allocates the proper airflow into its as-signed space to achieve the desired com-fort and ventilation levels.
Pressure Dependent Zone Dampers areused in air conditioning systems that do notrequire pressure independent airflow con-trol. If your system requires pressure inde-pendent control of the airflow, see the“2ZMD00471xxxx series - Pressure Inde-pendent Zone Damper - Fahrenheit” datasheet for the correct specifications.
All Zone Dampers are tested and certifiedin accordance with ARI standard 880. An ARI label is affixed to all units.
MountingThe Zone Damper assembly should be mounted according to standard duct installation practices with airflow di-rection as shown in the illustration above. After installation of the Zone Damper in the ductwork, insulation shouldbe applied around any remaining uninsulated surface on the air valve inlet and outlet. The Zone Damper shouldbe mounted so the control enclosure is positioned to the left or right side of the ductwork with the control enclo-sure in a vertical plane. Do not mount the Zone Damper Assembly with the control enclosure on the top or bottomof the ductwork. Adequate clearance should be maintained between the control panel and any obstruction to allowfor removal of the control panel cover and access to the controls.

Zone Damper SizingUse a load program to determine the peakload for each zone. These calculations will beused to select Zone Damper sizes.
The Meridian Systems utilize a typical lowpressure duct design. To reduce noise prob-lems, duct pressures should not exceed 1”W.C.
Primary trunk ducts used with Meridian sys-tems should not be “undersized”. This is es-pecially true of “pressure dependent” sys-tems. With larger trunk ducts, it is easier toassure relatively constant pressure to eachZone Damper. Runs should be as short aspossible, and the trunk duct system kept assymmetrical as possible to facilitate systembalancing. Wherever possible, run the trunkducts above corridors and locate the ZoneDampers above corridors to reduce the noisein the space and facilitate service of thevalves. Trunk ducts should be sized for nomore than 0.1” W.C. drop per 100 ft. of duct,and a maximum duct velocity of 2000 FPM.
Using the maximum acceptable velocity for abranch duct (typically 1000-1500 FPM forminimal noise), find the smallest ZoneDamper that will deliver the required CFM asdetermined by the load program.

The Zone Controller (2ZC0047000124) ismicroprocessor based and communicateswith the Zone Manager on the Meridiannetwork communications loop. The ZoneController monitors the space temperatureand allocates the proper airflow into its as-signed space to achieve the desired com-fort and ventilation levels.
Pressure Dependent Zone Dampers areused in air conditioning systems that do notrequire pressure independent airflow con-trol. If your system requires pressure inde-pendent control of the airflow, see the“2ZMD004701xxxxx series - Pressure In-dependent Zone Damper - Celsius” datasheet for the correct specifications.
All Zone Dampers are tested and certifiedin accordance with ARI standard 880. An ARI label is affixed to all units.
MountingThe Zone Damper assembly should be mounted according to standard duct installation practices with airflow di-rection as shown in the illustration above. After installation of the Zone Damper in the ductwork, insulation shouldbe applied around any remaining uninsulated surface on the air valve inlet and outlet. The Zone Damper shouldbe mounted so the control enclosure is positioned to the left or right side of the ductwork with the control enclo-sure in a vertical plane. Do not mount the Zone Damper Assembly with the control enclosure on the top or bottomof the ductwork. Adequate clearance should be maintained between the control panel and any obstruction to allowfor removal of the control panel cover and access to the controls.

Zone Damper SizingUse a load program to determine the peakload for each zone. These calculations will beused to select Zone Damper sizes.
The Meridian Systems utilize a typical lowpressure duct design. To reduce noise prob-lems, duct pressures should not exceed 1”W.C.
Primary trunk ducts used with Meridian sys-tems should not be “undersized”. This is es-pecially true of “pressure dependent” sys-tems. With larger trunk ducts, it is easier toassure relatively constant pressure to eachZone Damper. Runs should be as short aspossible, and the trunk duct system kept assymmetrical as possible to facilitate systembalancing. Wherever possible, run the trunkducts above corridors and locate the ZoneDampers above corridors to reduce the noisein the space and facilitate service of thevalves. Trunk ducts should be sized for nomore than 0.1” W.C. drop per 100 ft. of duct,and a maximum duct velocity of 2000 FPM.
Using the maximum acceptable velocity for abranch duct (typically 1000-1500 FPM forminimal noise), find the smallest ZoneDamper that will deliver the required CFM asdetermined by the load program.

It also includes (1)slave wiring interface card kit shipped loosefor field mounting to the master zone damperassembly. This kit contains a slave wiringinterface card and a cable.
The Slaved-Zone Damper, is used in sys-tems when it is not possible or practical touse a single large Zone Damper to satisfythe zones CFM requirements.
A total of two Slaved-Zone Dampers may beused in conjunction with a master ZoneDamper. The Slave Damper(s) are wired inparallel with the master Zone Damper andtrack the movement of the master ZoneDamper. Connection of the master ZoneDamper requires a slave wiring interface kitwhich is shipped loose for field mounting tothe master Zone Damper and is suppliedwith each Slaved-Zone Damper. The kit con-nects the Zone controller on the master tothe master actuator and provides wiring ter-minals for wiring to the Slaved-Zone Damp-ers. Only (1) of these kits is required for eachmaster/slave installation.
All Slaved-Zone Dampers are tested andcertified in accordance with ARI standard880. An ARI label is affixed to all units.
The Slaved-Zone Damper Assembly should be mounted according to standard duct installation practices with airflow direction as shown in the illustration above. After installation of the Air Damper in the ductwork, insulationshould be applied around any remaining uninsulated surface on the air valve inlet and outlet. The Air Dampershould be mounted so the control enclosure is positioned to the left or right side of the ductwork with the controlenclosure in a vertical plane. Do not mount the Air Damper Assembly with the control enclosure on the top orbottom of the ductwork. Adequate clearance should be maintained between the control panel and any obstructionto allow for removal of the control panel cover and access to the controls.

Use a load program to determine the peak load foreach zone. These calculations will be used in se-lecting the appropriate Zone and Slaved-ZoneDamper sizes. Only pressure dependent ZoneDampers may be slaved.
The Meridian Systems utilize a typical low pres-sure duct design. To reduce noise problems, ductpressures should not exceed 1” W.C.
Primary trunk ducts used with Meridian systemsshould not be “undersized”. With larger trunkducts, it is easier to assure relatively constantpressure to each Zone Damper. Runs should beas short as possible, and the trunk duct systemkept as symmetrical as possible to facilitate sys-tem balancing. Wherever possible, run the trunkducts above corridors and locate the master Zoneand Slaved-Zone Dampers above corridors to re-duce the noise in the space and facilitate serviceof the valves. Trunk ducts should be sized for nomore than 0.1” W.C. drop per 100 ft. of duct, and amaximum duct velocity of 2000 FPM.
Up to a maximum of two additional Slaved-ZoneDampers may be connected together with themain Zone Damper(s) for large zone air flow re-quirements. This design should be reserved onlyfor situations when it is not practical to use a singlelarge Zone Air Damper.
It is recommended that the Slaved-Zone Damper(s) shouldbe of the same size as the master Zone Damper. This in-sures that adequate air flow and minimum noise will occurat all damper positions.
Divide the total zone CFM required by the total number ofair valves to be used.
Using the maximum acceptable velocity for a branch duct(typically 1000-1500 FPM for minimal noise), go to the AirDamper Selection Data Chart below and find the quantityand size of Air Dampers that will deliver the required CFMas determined by the load program
Compare the Zone and Slaved-Zone Dampersizes selected against the branch duct sizes todetermine if the next size up or down will pro-vide acceptable performance without requiringa transition fitting.

The Meridian 1ZRD00470xxxx Series Rectan-gular Damper is used in applications whererectangular duct is specified or required be-cause of space limitations or job requirements.The Rectangular Damper utilizes opposedblades of airfoil design for improved air flowcontrol. The Rectangular Damper frame is madeof .080 thick extruded aluminum. The blades arealso made of extruded aluminum. Blade pins are7/16” hexagon shaped aluminum fixed to a Cel-con inner bearing rotating within a polycarbonateouter bearing inserted in the damper frame. TheDamper linkage is mechanically assembled andlocated in the damper frame . The linkage com-ponents are constructed of aluminum, zinc andnickel plated steel. Blade gaskets are made ofextruded EPDM material and are secured withinan integral slot on the blade. Jamb seals are ofextruded TPE material for low leakage throughthe damper when closed. The control shaft is1/2” diameter hexagon shaped rod and can beextended 9” past the damper frame for connec-tion to the damper actuator. The damper shaft isshipped retracted into the frame area and mustbe adjusted to the required length in the field.
The Rectangular Damper should be mounted inthe ductwork according to standard duct instal-lation practices. The rectangular damper shouldbe selected for the nominal inside duct size (SeeFigure 3). All Rectangular Dampers are supplied with 1” flanges all around damper frame, making the overalldamper width and height 2” larger than the nominal inside duct size thus providing for external flange mounting toductwork. The damper shaft is shipped retracted into the damper frame. Loosen the two nuts on the U-bolt thatsecures the damper shaft to the damper blade and adjust to length. It is recommended that the shaft length beadjusted so approximately 4” of shaft extends beyond the inside of the damper frame. Retighten the two nuts onthe U-bolt that secures the damper shaft to the blade. After installation of the Rectangular Damper to the duct-work, it is recommended that insulation be applied around any non-insulated surface on the ductwork where theRectangular Damper was installed.
Use a load program to determine the peak load for each zone. These calculations will be used in selecting theappropriate Rectangular Damper sizes. The Meridian Systems utilize a typical low pressure duct design. To re-duce noise problems, duct pressures should not exceed 1” W.C.
Primary trunk ducts used with Meridian systems should not be “undersized”. This is especially true of “pressuredependent” systems. With pressure independent systems this is not as critical. With larger trunk ducts, it is easierto assure relatively constant pressure to each Rectangular Damper. Runs should be as short as possible, and thetrunk duct system kept as symmetrical as possible to facilitate system balancing. Wherever possible, run the trunkducts above corridors and locate the Rectangular Dampers above corridors to reduce the noise in the space andfacilitate service of the valves. Trunk ducts should be sized for no more than 0.1” W.C. drop per 100 ft. of duct,and a maximum duct velocity of 2000 FPM.

Using the maximum acceptable velocity for abranch duct (typically 1000-1500 FPM forminimal noise), find the smallest damper thatwill deliver the required CFM as determined bythe load program.
Locate the required CFM on the RectangularDamper Selection Data table below. This tableis based on an airflow velocity of 1000 FPMacross the damper. This is the recommendedvelocity for quiet operation and normal pres-sure drop through the damper.

Notes:1. The table above is calculated based on 1000 FPM velocity across the full open damper. For other velocities use the
following multipliers to obtain the correct CFM: 500 FPM = 0.5, 1500 FPM = 1.5, 2000 FPM = 2.0. It is recommendedthe damper velocity does not exceed 1500 FPM for quiet operation.
2. Pressure drop (∆PS) is based on 1000 FPM Velocity. Any pressure drop less than 0.01” W.C. is shown as (-).
When space considerations or design criteria dictate, dampersmay be selected for other face velocities by using the multipli-ers listed in the notes associated with the table. Move acrossthe table and find the damper selection which will provide therequired CFM and fit within the ceiling area where the damperwill be located. Many size selections are possible for a givenCFM. Pressure drop across the damper is shown in parenthe-sis below the CFM.

The patented design of the York Meridian RoomSensor provides accurate sensing of the roomtemperature. Its design allows for flush wallmounting yet rejects the influence of surface andinternal wall temperatures. The Room Sensor’sattractive styling and off white casing color make itsuitable for most building decors. If interior deco-ration requires, the Zone Sensor casing can alsobe painted or wall papered without affecting thesensor's performance. Room Sensors are avail-able in 4 different configurations:
• 2ZTS004704024 - Sensor Plain• 2ZTO004704024 - Sensor with Setpoint
Adjustment• 2ZTA004704124 - Sensor with Override• 2ZTB004704124 - Sensor with Setpoint
Adjustment and Override
The Room Sensor Plain and Room Sensor withOverride, require (2) wires to be connected fromthe controller to the sensor. The Room Sensorwith setpoint adjustment and Zone Sensor withSetpoint and Override options, require 3 wires beconnected to the sensor. Twisted cable is rec-ommended for wiring of all Room Sensors. Wiringshould not be run in conduit with other AC linevoltage wiring, or with any conductors carryinghighly inductive loads. Most applications do notrequire shielding.
The Room Sensors are designed to be mounted on a vertical, 2” x 4” electrical box recessed in the wall. If the wallcannot be penetrated, a plastic surface mount box such as those made by Wiremold, may be used to mount thesensor to the wall surface.

2. Use the voltage column to check sensors while connected to powered controllers. Read voltage with meter set on DC volts.Place the "-"(minus) lead on GND terminal and the "+"(plus) lead on the sensor input terminal being investigated. If the voltageis above 5.08 VDC, the sensor or wiring is "open." If the voltage is less than 0.05 VDC, the sensor or wiring is shorted.
The Duct Sensor Is Used For Sensing SupplyOr Return Air Temperatures. Location Of TheSensors Is Very Important In Order To ObtainAccurate Temperature Readings. TheFollowing Recommendations Should BeFollowed:
When Used As A Supply Air Sensor TheSensor Should Be Mounted In The Supply AirDuct As Close To The HVAC Unit As PossibleAnd Upstream Of The Bypass Damper (IfUsed) For Best Results. For Best Accuracy,Apply Insulation On The Outside Of TheDuctwork Over The Sensor. This Will HelpThermal Gradients From Affecting The Sensor.
