†
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 for operation of 1 speed or 2 speed sup-
ply fan.
NOTE: 2-speed fan option also needs 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 thermostat 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 fac-
tory 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
temperature 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 sec-
ond stage. Allows three stages of cooling, 1 economizer and 2 mechan-
ical.
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 conven-
tional 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 dis-
play.
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 dis-
play.
based on the RA, OA, and MA sensor conditions. Requires all 3 RA, OA,
and MA sensors.
