EXPANDED PARAMETER NAME/NOTES
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
(Not available on 2-speed configuration)
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
ON = 24 Vac on terminal Y1-O; Stage 1 mechanical cooling called on
OFF = 0 Vac on terminal Y1-O; no mechanical cooling
SECOND STAGE COOLING DEMAND (Y2–IN)
Y2–I signal from space thermostat or unitary controller for cooling stage 2.
ON = 24 Vac on terminal Y2–I
OFF = 0 Vac on terminal Y2–I
SECOND STAGE COOLING RELAY OUTPUT
ON = 24 Vac on terminal Y2-O; Stage 2 mechanical cooling called on
OFF = 0 Vac on terminal Y2-O; no Stage 2 mechanical cooling
SUPPLY AIR TEMPERATURE, Cooling Mode
Displays value of measured mixed 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 _ _ . _ if sensor sends invalid value, if not connected, short or
out-of-range.
OUTSIDE AIR TEMP
Displays measured value of outdoor air temperature.
Displays _ _ . _ if sensor sends invalid value, 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.
RETURN AIR RELATIVE HUMIDITY
(Accessory enthalpy sensor required)
Displays measured value of return air humidity from RA sensor.
SPACE/RETURN AIR CO
2
(CO
sensor required, accessory or factory option)
2
Displays value of measured CO
from CO
2
Invalid if not connected, short or out-of-range
DEMAND CONTROLLED VENTILATION STATUS
(CO
sensor required, accessory or factory option)
2
Displays ON if IN CO
value above setpoint DCV SET and OFF if below
2
setpoint DCV SET.
Displays voltage output to the damper actuator.
2.0V = OSA damper fuily closed
10.0V = OSA damper fully open
Displays actual position of outdoor air damper actuator
0% = OSA damper fuily closed
100% = OSA damper fully open
sensor.
