FIRST STAGE COOLING DEMAND (Y1–IN)
YES = economizing available; the system can use outside air for free cooling
when required
FIRST STAGE COOLING RELAY OUTPUT
YES = outside air being used for 1 stage cooling
OCCUPIED
YES = OCC signal received from space thermostat or
unitary controller
YES = 24 Vac on terminal OCC
NO = 0 Vac on terminal OCC
HEAT PUMP MODE
Displays COOL or HEAT when system is set to heat pump
(Non-conventional)
FIRST STAGE COOLING DEMAND (Y1-IN)
Y1–I signal from space thermostat or unitary controller for cooling stage 1.
ON = 24 Vac on terminal Y1–I
OFF = 0 Vac on terminal Y1–I
FIRST STAGE COOLING RELAY OUTPUT
Cool stage 1 Relay Output to stage 1 mechanical cooling
(Y1–OUT terminal)
SECOND STAGE COOLING DEMAND (Y2–IN)
Y2–I signal from space thermostat our unitary controller for second stage cool-
ing.
ON = 24 Vac on terminal Y2–I
OFF = 0 Vac on terminal Y2–I
SECOND STAGE COOLING RELAY OUTPUT
Cool Stage 2 Relay Output to mechanical cooling
(Y2–OUT terminal)
SUPPLY AIR TEMPERATURE, Cooling Mode
Displays value of measured mixed air from MAT sensor.
Displays _ _ . _ F if not connected, short or out-of-range.
DISCHARGE AIR TEMPERATURE, after Heating section
Displays when Discharge Air sensor is connected and displays measured dis-
charge temperature.
Displays _ _ . _F if sensor sends invalid value, if not connected, short or out-of-
range.
OUTSIDE AIR TEMP
Displays measured value of outdoor air temperature.
Displays _ _ . _F if sensor sends invalid value, short or
out-of-range.
OUTSIDE AIR RELATIVE HUMIDITY
Displays measured value of outdoor humidity from
OA sensor.
Displays _ _% if not connected short, or out-of-range.
RETURN AIR TEMPERATURE
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
RETURN AIR RELATIVE HUMIDITY
Displays measured value of return air humidity from
RA sensor.
Displays _ _% if sensor sends invalid value, if not connected, short or out-of-
range
SPACE/RETURN AIR CO

Displays value of measured CO from CO
2
short or out-of-range
DEMAND CONTROLLED VENTILATION STATUS
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.
Displays actual position of outdoor air damper actuator
