SYSTEM SETUP
INSTALL 01/01/17 N/A Display order = MM/DD/YY
Setting order = DD, MM, then YY.
UNITS DEG F F or C Sets economizer controller in degrees Fahrenheit or Celsius
EQUIPMENT CONV Conventional or HP CONV = conventional;
HP O/B = Enable Heat Pump mode. Use AUX2 I for Heat Pump input from
thermostat 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
2SP H/C
3 speed
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.

The value is found on the nameplate label for the specific unit.
AUX1 OUT NONE NONE
ERV
EXH2
SYS
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
OCC INPUT INPUT or ALWAYS 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.
FACTORY DEFAULT NO NO or YES 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.

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
SD 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 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.

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.
