EXPANDED PARAMETER NAME
[
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 mechanical cooling (Y1---OUT terminal).
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
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 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 --- ---.---_F if sensor sends invalid value, if not connected, short or
out---of---range.
OUTSIDE AIR TEMPERATURE
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 CO2
(CO sensor required, accessory or factory option)
2
Displays value of measured CO
2
Invalid if not connected, 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_ 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
programmed percentage setpoint.
ON = 24 Vac Output; OFF = No Output.
EXHAUST STAGE 2 RELAY OUTPUT
Output of AUX1 O terminal Displays ON when damper position reaches
programmed percentage setpoint
ON = 24 Vac Output, OFF = No Output; displays only if AUX1 O =
EXH2
ENERGY RECOVERY UNIT RELAY OUTPUT
Output of AUX1 O terminal, ON = 24 Vac Output, OFF = No Output;
displays only if AUX1 O = ERV
Displays stage of mechanical cooling that is active.
Displays the stage of heat pump heating that is active
SUPPLY FAN SPEED
Displays speed setting of fan on a 2---speed fan unit.
HEAT DEMAND STATUS
Displays status of heat demand on a 2---speed fan unit.
