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 cooling.
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 discharge 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
2
Displays value of measured CO
connected, 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.
2
Displays voltage output to the damper actuator.
Displays actual position of outdoor air damper actuator.
Displays number of times actuator has cycled.
1 cycles equals 180 deg. of actuator movement in any direction.
Displays ERROR if voltage or torque is below actuator range.
EXHAUST STAGE 1 RELAY OUTPUT
Output of EXH1 terminal:
ON = relay closed
OFF = relay open
EXHAUST STAGE 2 RELAY OUTPUT
Output of AUX terminal; displays only if AUX = EXH2
ENERGY RECOVERY VENTILATOR
Output of AUX terminal; displays only if AUX = ERV
