thermostat or controller.
See Menu Note 4.

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 availa
b
le 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.

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 set
b
ack thermostat with occupancy out (24 vac), the 24 vac
is input “INPUT” to the OCC terminal. If no occupancy output from the ther-
mostat 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

when economizer is first stage and mechanical cooling is second stage.
Allows three stages of cooling, 1 economizer and 2 mechanical.

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.
