Use AUX2 I for Heat Pump input fromthermostat or controller.See Menu Note 4.AUX2 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 for W.Shutdown is not available in 2-speed fan mode. See Menu Note 4.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 speed Sets the economizer controller for operation of 1 speed or 2 speed supply fan.NOTE: 2-speed fan option also needs Heat (W1) programmed in AUX 2 In.See Menu Note 4.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 NONE NONEERVEXH2SYSSelect 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 ALWAYS OCCUPIED MODE BY EXTERNAL SIGNALWhen using a setback thermostat with occupancy out (24 vac), the 24 vac isinput “INPUT” to the OCC terminal. If no occupancy output from the thermostatthen change program to “ALWAYS” OR add a jumper from terminal R to OCCterminal.FACTORY DEFAULT NO NO or YES Resets all set points to factory defaults when set to YES. LCD will briefly flashYES and change to NO but all parameters will change to the factory defaultvalues.NOTE: RECHECK AUX2 IN and FANTYPE for required 2-speed values.ADVANCEDSETUPMA LO SET 45°F 35 to 55 F;Incremented by 10 SUPPLY AIR TEMPERATURE LOW LIMITTemperature to achieve Freeze Protection (close damper and alarm if tem-perature 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 0ppm 0 to 500 ppm;Increment by 10 CO2 ppm level to match CO 2 sensor start level.CO2 SPAN 2000ppm 1000 to 3000 ppm;Increment by 10 CO2 ppm span to match CO 2 sensor.STG3 DLY 2.0h 0 min, 5 min, 15 min,then 15 min intervals.Up to 4 hrs or OFFCOOLING STAGE 3 DELAYDelay after stage 2 cool has been active. Turns on second stage of coolingwhen economizer is first stage and mechanical cooling is second stage.Allows three stages of cooling, 1 economizer and 2 mechanical.OFF = no Stage 3 coolingSD DMPR POS CLO CLO or OPN Indicates shutdown signal from space thermostat or unitary controller. Whencontroller receives 24 Vac input on the SD terminal in conventional mode, theOA damper will open if programmed for OPN and OA damper will close if pro-grammed 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 lower range ofalarm, below this temperature the alarm will show on the display.DA HI ALM 80 F (27 C) 70 to 180 F; (21 to82 C) Incrementedby 5 deg.Used for alarm for when the DA air temperature is too high. Set upper range ofalarm, above this temperature the alarm will show on the display.DCVCAL ENA MAN MAN (manual) AUTO Turns on the DCV automatic control of the dampers. Resets ventilation basedon the RA, OA, and MA sensor conditions. Requires all 3 RA, OA, and MAsensors.
