YES = economizing available; the system can use
outside air for free cooling when required
YES = outside air being used for 1
YES = OCC signal received from space thermostat
or unitary controller.
YES = 24 Vac on terminal OCC.
NO
= 0 Vac on terminal OCC.
Displays COOL or HEAT when system is set to heat pump
(non---conventional)
Y1---I signal from space thermostat or unitary controller for cooling stage
1.
ON
= 24 Vac on terminal Y1---I
OFF = 0Vac on terminal Y1---I
Cool stage 1 Relay Output to stage 1 mechanical cooling (Y1---OUT
terminal)
Y2---I signal from space thermostat our unitary controller for second
stage cooling.
ON
= 24 Vac on terminal Y2---I
OFF = 0 Vac on terminal Y2---I
Cool Stage 2 Relay Output to mechanical cooling (Y2---OUT terminal).
Displays value of measured mixed air from MAT sensor.
Displays --- ---.--- if not connected, short or out---of---range.
Displays when Discharge Air sensor is connected and displays measured
discharge temperature.
Displays _ _ . __F if sensor sends invalid value, if not connected, short or
out---of---range.
Displays measured value of outdoor air temperature.
Displays _ _ . __F if sensor sends invalid value, if not connected, short or
out---of---range.
Displays measured value of outdoor humidity from OA sensor.
Displays _ _% if not connected short, or out---of---range.
Displays measured value of return air temperature from RAT sensor.
Displays _ _ . __F if sensor sends invalid value, if not connected, short
or out---of ---range.
Displays measured value of return air humidity from RA sensor.
Displays _ _% if sensor sends invalid value, if not connected, short or
out---of---range.
Displays value of measured CO
connected, short or out---of---range.
Displays ON if above setpoint and OFF if below setpoint, and ONLY if a
CO
sensor is connected.

Displays voltage output to the damper actuator.
Output of EXH1 terminal:
ON
= relay closed
OFF = relay open
Output of AUX terminal; displays only if AUX = EXH2
