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
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
ON
= relay closed
OFF = relay open
Displays stage of mechanical cooling 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.
