EXPANDED PARAMETER NAME
{
ECONOMIZING AVAILABLE
YES = economizing available; the system can use outside air for free
cooling when required
ECONOMIZING ACTIVE
YES = Outside air being used for Cooling Stage 1.
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 = 0Vac 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 STAVE 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/cooled air from SAT sensor in fan
section.
Displays --- ---.--- if not connected, short or out---of---range. See Menu 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 TEMPERATURE
Displays measured value of outdoor air temperature.
Displays --- --- --- --- --- --- 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.
RETURN AIR RELATIVE HUMIDITY
(Accessory enthalpy sensor required)
Displays measured value of return air humidity from RA sensor.
SPACE/RETURN AIR CO2
(CO sensor required, accessory or factory option)
2
Displays value of measured 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.
0% = OSA Damper fully closed
100% = OSA Damper full open
Displays actual position of outdoor air damper actuator
2.0V = OSA Damper fully---closed
10.0V = OSA Damper full open
Displays number of times actuator has cycled.
1 Cycle equals accrued 180_ of actuator movement in any direction
Displays Error if voltage or torque is below actuator range
30
