ECONOMIZING AVAILABLE
YES = economizing available; the system can use outside air for free cool-
ing when required
ECONOMIZING ACTIVE
YES = Outside air being used for 1 stage cooling
NO = Economizing not active
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/cooled air from SAT sensor in fan
section.
Displays _ _ . _ if not connected, short or out-of-range. See Note 2.
DISCHARGE AIR TEMPERATURE, after Heating section
(Accessory sensor required)
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, if not connected, short or
out-of-range.
OUTSIDE AIR RELATIVE HUMIDITY
Displays measured value of outdoor humidity from OA enthalpy sensor.
RETURN AIR TEMPERATURE
(Accessory sensor required)
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
(Accessory enthalpy sensor required)
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
(CO sensor required, accessory or factory option)
2
Displays value of measured CO
nected, short or out-of-range. May be adjusted in Advanced menu by Zero
offset and Span.
DEMAND CONTROLLED VENTILATION STATUS
(CO sensor required, accessory or factory option)
2
Displays ON if IN CO2 value above setpoint DCV SET and OFF if below
setpoint DCV SET.
Displays output voltage or position to the damper actuator.***
Displays actual position of outdoor air damper actuator
Displays number of times actuator has cycled.
1 cycle equals accrued 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. Displays On when damper position reaches pro-
grammed percentage setpoint.
ON = 24 Vac Output; OFF = No Output.
