Files needed for update

Files needed to upgrade Prodigy controller from USB stick:

1) For DB1: DBxxxxxx.BIN2) For M2: M2xxxx.SL1

The “xxx” here are place holders for version numberinformation in the actual file names, and varies from oneversion to the next.

The DB1 upgrade file has a BIN file extension, and must belocated in the root folder of the thumb drive. No more than 10

files should be in the root folder of the thumb drive. If locatedanywhere else the Prodigy will not find the DB1 file.

The M2 upgrade file has an SL1 file extension, and must belocated in the \firmware\m2 folder of the thumb drive. Iflocated anywhere else the Prodigy will not find the M2 file.

DB1 FIRMWARE NOTE: The menus described in thefollowing will only be available for v1.09.xx H and laterversions of the DB1 firmware.

After inserting the USB stick, navigate to SERVICE >SOFTWARE RECOVERY > UPDATE M2 SOFTWARE (orUPDATE DB1 SOFTWARE). Press the select button, thenuse the up/down arrows to select a firmware version. Pressselect; “CHECKING FILE” will display first; then“UPDATING”, followed by “NN%”.

Connections between RTU & M2 unit controller

The M2 unit controller connects to the rooftop unit usingSmartWire� connectors. Each connector is “keyed” so thatno connector can be installed in the wrong location. Be sureall connectors are in place and completely inserted (seefigure 1).

Sensor Common Isolation

Thermostat (TSTAT) and humidity (HUM) sensor commonsmay be isolated if they are powered remotely. Slide switch toOPEN to isolate (see figure 1).

USB interface usage

The USB port is used for verifying service, downloadingreports, transferring unit profiles and performing firmwareupdates. Onsite data collection requires use of a USB flashdrive. Data written to the drive includes date, time, serialnumber, catalog number, basic data, error code buffer, andunit configuration.

PC interface

The PC interface is used with unit controller software tochange programming. The M2 interface uses a USB A to Bmale cable. You may also use a 9 pin/RS485 connection tothe phone jack or S-BUS connector. A list of serviceconnection kits is on Page 27.

SmartWire� Field Wiring Connections

The SmartWire� connectors, P297, P298 and P299, allow

for easy field wiring connection points.

2-amp fuse or wire jumper

The 24VAC supply outputs, (R), on these connectors arerouted through the 2-amp fuse, F1, on earlier boards or awire jumper on later boards.

TSTAT COM switch (earlier boards) OR TSTAT COM wire jumpers (later boards)

TSTAT COM is located to the left of P297. This switch wouldbe set to the LEFT or the wire jumpers would be cut only inunique situations where the device supplying the thermostatsignals to the Prodigy® controller has its own power sourceand does not share a common reference voltage with theProdigy controller. Otherwise the switch needs to be set tothe default, closed position, to the RIGHT and the wirejumper would remain intact, as shipped from the factory.

HMD COM switch (earlier boards) OR HMD COM wire jumpers (later boards)

HMD COM is located to the left of P299. This switch wouldbe set to the RIGHT or the wire jumpers would be cut only inunique situations where the device supplying the thermostatsignals to the Prodigy controller has its own power sourceand does not share a common reference voltage with theProdigy controller. Otherwise the switch needs to be set tothe default, closed position, to the LEFT and the wire jumperwould remain intact, as shipped from the factory.

User interface menu

The user interface is accessed through the menu navigationarrows and the select button . The diagram infigure 2 shows a high level overview of the main menuoptions along with the next level list of selections. The lowerlevel options are described later in this manual.

“Home” location, DISPLAY—When the unit is powered on,one of the features in the DISPLAY column will be shown (theword 'DISPLAY' is never shown). What is displayed in this“home” screen, is dependant on the priority message present

at the time, in priority order of top-to-bottom of the left columnin figure 2. For example, if an alarm is present, that will bedisplayed until it has been silenced or cleared.

To access the other three columns, first press and thenuse to scroll between SERVICE, DATA, ANDSETTINGS. Next, press to open the SERVICE (or DATAor SETTINGS) menu. Use until desired item isdisplayed.

To return to DISPLAY, use (if deep in the menu structure,hold it down; it will step back to display).

Unit Operation

This section describes the display and control buttons, howto configure the unit, and how to read stored configurationdata, status, and alarms.

The M2 unit controller is an input and output junction point.If in the thermostat mode, thermostat inputs at P297 resultin an output to unit components (see table 9 on Page 41). Ifthe heartbeat LED is not flashing, see table 1 (Page 4) forheartbeat operation. If the display shows an alarm, refer totable 8 (Page 31) for more information. If the thermostatinput indicating lights are not responding appropriately,check the thermostat or a DDC control acting asthermostat inputs into P297.

Basic cooling and heating functions may be energized to testmajor unit components by using the M2 unit controller testingfunction or by using jumper wires on the Field WiringTermination plug P297.

To access the other three columns, first press and thenuse to scroll between SERVICE, DATA, ANDSETTINGS. Next, press to open the SERVICE (or DATAor SETTINGS) menu. Use until desired item isdisplayed.

Blower Operation with Occupancy and CEC Title 24

The blower runs to service heat and cool demands,regardless of the space occupancy. But when there is noheating or cooling demand there are options for how theblower should operate in conjunction with occupancy signalsto keep the space ventilated, or the air stirred.

In SETTINGS>CONTROL menus the option for BLOWERON OCP is selected as CYCLES or ALWAYS ON. Thesecorrespond to ECTO 6.17 settings of 0 or 1, respectively.These settings govern whether the blower runs continuouslywhen the space is considered occupied (=1), or cycles on/offwith the heating and cooling demand (=0). ECTO 6.17 onlyapplies to the room sensor control modes, and not to the localor network thermostat modes. In those modes the blower iscontrolled by the G thermostat or DDC signal.

To comply with the California Energy Commission Title 24standard there are two additional blower/occupancy settingsthat are set directly by changing ECTO 6.17 from theSETTINGS>CONTROL>ECTO menu. These two additional

options are available when using LonTalk or BACnetnetworks that supply a room occupancy signal (in addition tothe scheduled occupancy). The same two options are alsoavailable when using the Lennox L Connection network withcomfort sensors that have added an optional roomoccupancy sensor. If a room occupancy sensor is notinstalled and configured on the network, then options 0 and 1for ECTO 6.17 as previously described should continue to beused.

The two new ECTO 6.17 options for CEC Title 24 are:

� ECTO 6.17 = 2: Blower runs when both the occupancyscheduler and the room occupancy sensor indicate thatthe space is occupied.

� ECTO 6.17 = 3: Same as option 2, but the blower alsoruns for 30 minutes and is OFF for 90 minutes when theoccupancy scheduler indicates occupied but the roomoccupancy sensor indicates that the space is notoccupied.

Page 24

Economizer (Damper)

General

The economizer, when configured, controls

� damper position, which determines how much outdoorair is used to meet free cooling or indoor air quality (IAQ)requirements, and

� the optional power exhaust fans.

On a cooling demand, outdoor air is used for free coolinginstead of first-stage compressor(s) when outdoor air issuitable (OAS).

Outdoor Air Suitable (OAS) LED (Early M2 hardware)

A yellow LED which is labeled OAS provides economizerstatus. A steady yellow LED indicates that outdoor air issuitable for free cooling. A flashing yellow OAS light indicatesthe IAQ sensor requires outdoor air. (A flashing yellow LEDcan also mean that the economizer dampers are open tobring in fresh air while a compressor is on.) If the economizeris already operating, a flashing yellow OAS light indicates theIAQ sensor requires more outdoor air than is suitable for freecooling.

DIP Switch Settings (Early M2 hardware)

The DIP switch setting determines the mode used to enablefree cooling. The DIP switch also has a mode to set thedamper minimum position and test damper operation. DIPswitch is factory-set when the economizer isfactory-configured.

Free Cooling Discharge Air Setpoint

When outdoor air conditions are suitable and economizer isset to provide free cooling, dampers will modulate to achievea discharge air temperature of 55°F (13°C) default. Thissetpoint is adjustable between 45° and 65°F.

The setpoint can also be automatically increased whenoutdoor or return air temperatures drop. See Outdoor AirReset and Return Air Reset in the Discharge Air Controlsection in the Prodigy Application Guide (AdvancedFeatures) manual. These settings must be enabled andadjusted using the Prodigy CONTROL/ECTO menu to makechanges to ECTO values. Refer to the Prodigy ApplicationGuide. The unit does not have to be operating in discharge aircooling mode to adjust the free cooling discharge air setpoint,or to use setpoint reset.

During free cooling operation, the damper modulates tomaintain a discharge air temperature equal to the freecooling discharge air setpoint. If the damper has beencontinuously at its maximum open position for at least threeminutes, then a second stage cooling demand will be allowedto turn on the first stage of mechanical cooling. While themechanical cooling is on, the damper is held to its maximumposition, and does not modulate until the second stagedemand is satisfied. On a third stage cooling demand, thesecond stage of mechanical cooling will be turned on.

Outdoor Air Suitability

There are five modes which can be used to determine if theoutdoor conditions will enable free cooling.

� Old hardware: DIP switch is set toODE (Outdoor Enthalpy), and theEnthalpy Setpoint potentiometeris set A-through-D.

� New hardware: Configuration isset to Single EnthalpyEconomizer Control and ECTO 6.26 setpoint value isset to between 12 and 19mA, 150 to 240 counts.

Enthalpy Setpoint

This setting pertains to the ODE free cooling mode only. TheM2 will enable free cooling when outdoor air enthalpy (A7) isless than the enthalpy setpoint. Table 5 shows theapproximate enthalpy setpoints for each potentiometersetting at 50% relative humidity. The ECTO 6.26 column isthe correlating values used in the new hardware.

Example:—At setting “A”, the enthalpy control will modulatedampers open when outdoor air is at 73°F and 50% relativehumidity. If space temperatures are too warm, rotate thepotentiometer to “B” (old hardware) or enter a count of 173(ECTO 6.26 if new hardware). The enthalpy control will nowmodulate dampers open when outdoor air is 70°F and 50%relative humidity.

NOTE - When in outdoor enthalpy mode, a value between

130-240 counts is entered. When in differential enthalpy

mode a 2mA (or 26 count) difference between outdoor and

indoor enthalpy corresponds to about a 3.5°F difference in

temperature at constant relative humidity (or about a 12%RH

difference at constant temperature). When in differential

enthalpy mode, a value between 0-75 counts is entered.

Table 5. Enthalpy Control Setpoints

The recommended enthalpysetpoint is “A”. If the economizer is allowing air which is toowarm or too humid to enter thesystem, the enthalpy controlmay be changed to a lower setting (B, C, or D).

Economizer (Damper) (Continued)

There are six options available to determine outdoor airsuitability (OAS) for free cooling. See table 6. Economizersettings are shown for each mode in figure 4.The appropriate sensors are provided when the economizer

is factory-configured. When the economizer isfield-configured, the ODE mode requires additionalfield-provided sensor(s). See table 6. The TEMP mode usessensors provided with all units.

Mode Outdoor air is suitable for free cooling when:

TEMP OFFSET Outdoor air temperature (RT17) is less than return air temperature (RT16) by at least the OFFSET value.

TEMP OAT STPT Outdoor air temperature (RT17) is less than the OAT STPT value.

RemoteEither of the TEMP modes can be used when a network OAS signal is provided by an energy management or buildingcontrol system, via BACnet, LonTalk, or L Connection. The network can command OAS, NOT OAS, or AUTO. AUTOreturns to local control of OAS, which is the selected TEMP mode..

ENTH (differential)Outdoor air enthalpy* (A7) is less than return air enthalpy (A62) by at least the OFFSET value. (There is no OFFSETvalue in old hardware.)

ENTH (setpoint)Outdoor air enthalpy (A7) is less than enthalpy setpoint potentiometer position A, B, C, or D (for old hardware), or lessthan ECTO 6.26 STPT value (new hardware).

GLOBALGlobal input is energized by (P297-9). This setting is also used for outdoor air damper applications. Global input alsobrings on the blower. (This mode is NOT used when OAS signal is provided via network connection. GLO is only usedwhen a 24VAC signal is used to energize the P297-9 GLO input.)

Enthalpy includes effects of both temperature and humidity.
