Use AUX2 I for Heat Pump inputfrom thermostat or controller.See Menu Note 7AUX2 IN W SD/W or HP(O)/HP(B)In CONV mode:SD + Enables configuration of shutdown (default);W = Informs controller that system is in heating mode.NOTE: If using 2-speed fan mode, you must program CONV mode forW. Shutdown is not available in 2-speed fan mode. See Menu Note 7.In HP O/B mode:HP(O) = energize heat pump on Cool (default);HP(B) = energize heat pump on heat.FAN SPEED 2 speed 1 speed/2 speedSets the economizer controller for operation of 1 speed or 2 speed sup-ply fan.NOTE: 2-speed fan option also needs Heat (W1) programmed in AUX 2In. See Menu Note 7.FAN CFM 5000cfm 100 to 15000 cfm;increment by 100UNIT DESIGN AIRFLOW (CFM)Enter only if using DCVAL ENA = AUTOThe value is found on the nameplate label for the specific unit.AUX1 OUT NONENONEERVEXH2SYSSelect OUTPUT for AUX1 O relay• NONE = not configured (output is not used)• ERV = Energy Recovery Ventilator• EXH2 = second damper position relay closure for second exhaust fan• SYS = use output as an alarm signalOCC INPUT INPUT or ALWAYSOCCUPIED MODE BY EXTERNAL SIGNALWhen using a setback thermostat with occupancy out (24 vac), the 24vac is input “INPUT” to the OCC terminal. If no occupancy output fromthe thermostat then change program to “ALWAYS” OR add a jumperfrom terminal R to OCC terminal.FACTORY DEFAULT NO NO or YESResets all set points to factory defaults when set to YES. LCD will brieflyflash YES and change to NO but all parameters will change to the fac-tory default values.NOTE: RECHECK AUX2 IN and FANTYPE for required 2-speed values.ADVANCEDSETUPMA LO SET 45°F 35 to 55°F;Incremented by 10SUPPLY AIR TEMPERATURE LOW LIMITTemperature to achieve Freeze Protection (close damper and alarm iftemperature falls below setup value).FREEZE POS CLO CLO or MIN FREEZE PROTECTION DAMPER POSITIONDamper position when freeze protection is active (closed or MIN POS).CO2 ZERO 0 ppm 0 to 500 ppm;Increment by 10CO 2 ppm level to match CO 2 sensor start level.CO2 SPAN 2000 ppm 1000 to 3000 ppm;Increment by 10CO 2 ppm span to match CO2 sensor.STG3 DLY 2.0h 0 min, 5 min, 15min, then 15 minintervals. Up to 4hrs or OFFCOOLING STAGE 3 DELAYDelay after stage 2 cool has been active. Turns on second stage ofcooling when economizer is first stage and mechanical cooling is sec-ond stage. Allows three stages of cooling, 1 economizer and 2 mechan-ical.OFF = no Stage 3 coolingSD DMPR POS CLO CLO or OPN Indicates shutdown signal from space thermostat or unitary controller.When controller receives 24 Vac input on the SD terminal in conven-tional mode, the OA damper will open if programmed for OPN and OAdamper will close if programmed for CLO. All other controls, e.g., fans,etc. will shut off.DA LO ALM 45°F (7°C) 35 to 65°F; (2 to18°C) Incrementedby 5 deg.Used for alarm for when the DA air temperature is too low. Set lowerrange of alarm, below this temperature the alarm will show on the dis-play.DA HI ALM 80°F (27°C) 70 to 80°F; (21 to82°C) Incrementedby 5 deg.Used for alarm for when the DA air temperature is too high. Set upperrange of alarm, above this temperature the alarm will show on the dis-play.DCVCAL ENA MAN MAN (manual) AUTO Turns on the DCV automatic control of the dampers. Resets ventilationbased on the RA, OA, and MA sensor conditions. Requires all 3 RA, OA,and MA sensors.
