Display order = MM/DD/YY
Setting order = DD, MM, then YY.
Sets economizer controller in degrees Fahrenheit or Celsius
CONV = conventional;
HP O/B = Enable Heat Pump mode. Use AUX2 I for Heat Pump input from
thermostat or controller.
See Menu Note 4.
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.
Sets the economizer controller operation based on 1 speed, 2 speed,
2 speed heat/cool (2SP H/C), or 3 speed supply fan.
NOTE: Multi-speed fan options also need Heat (W1) programmed in AUX 2
In. See Menu Note 4.
UNIT DESIGN AIRFLOW (CFM)
Enter only if using DCVAL ENA = AUTO
The value is found on the nameplate label for the specific unit.
Select 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 signal
OCCUPIED MODE BY EXTERNAL SIGNAL
When using a setback thermostat with occupancy out (24 vac), the 24 vac is
input "INPUT" to the OCC terminal. If no occupancy output from the thermo-
stat then change program to "ALWAYS" OR add a jumper from terminal R to
OCC terminal.
Resets all set points to factory defaults when set to YES. LCD will briefly
flash YES and change to NO but all parameters will change to the factory
default values.
NOTE: RECHECK AUX2 IN and FANTYPE for required 2-speed values.
SUPPLY AIR TEMPERATURE LOW LIMIT
Temperature to achieve Freeze Protection (close damper and alarm if tem-
perature falls below setup value).
FREEZE PROTECTION DAMPER POSITION
Damper position when freeze protection is active (closed or MIN POS).

COOLING STAGE 3 DELAY
Delay after stage 2 cool has been active. Turns on second stage of cooling
when economizer is first stage and mechanical cooling is second stage.
Allows three stages of cooling, 1 economizer and 2 mechanical.
OFF = no Stage 3 cooling
Indicates shutdown signal from space thermostat or unitary controller. When
controller receives 24 Vac input on the SD terminal in conventional mode,
the OA damper will open if programmed for OPN and OA damper will close if
programmed for CLO. All other controls, e.g., fans, etc. will shut off.
Used for alarm for when the DA air temperature is too low. Set lower range
of alarm, below this temperature the alarm will show on the display.
Used for alarm for when the DA air temperature is too high. Set upper range
of alarm, above this temperature the alarm will show on the display.
based on the RA, OA, and MA sensor conditions. Requires all 3 RA, OA, and
MA sensors.
SUPPLY AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature sensor.
OUTSIDE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature sensor.
OUTSIDE AIR HUMIDITY CALIBRATION
Allows for operator to adjust for an out of calibration humidity sensor.
RETURN AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature sensor.
RETURN AIR HUMIDITY CALIBRATION
Allows for operator to adjust for an out of calibration humidity sensor.
DISCHARGE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature sensor.
TIME DELAY ON SECOND STAGE ECONOMIZING
When in economizing mode this is the delay for the high speed fan to try to
satisfy the call for second stage cooling before the first stage mechanical
cooling is enabled.
