70 - 72 RESERVED
73 ALARM NETWORK SENSOR ERROR Check with integrator for refresh rate, network status lights and wiring.
74 ALARM ZONE (ROOM) SENSOR A2
If measurement is out of specified range (including open/short detection) the system will ignore the Zone Temperature
Sensor readings and set the alarm.
If measurement of Zone Temperature Sensor is out of specified range (including open/short detection) the system will
change operating mode to the specified Backup mode (None, Local Thermistor or Return Air temp).
The system will clear the alarm, if zone temperature sensor measurement is detected in specified operating range and
return the system to monitoring the A2 sensor as the primary sensor input.
Check zone (room) sensor and wiring
75 ALARM OUTDOOR TEMPERATURE SENSOR (RT17)
if measurement of the outdoor temperature sensor is out of specified range (including open / short detection, the alarm will
be activated. alarm will automatically clear once in range condition is detected.
Check sensor and wiring.
76 ALARM HUMIDITY SENSOR A91
If measurement is below specified range ( <5 % RH) the system will ignore the Relative Humidity readings. If measurement
is above the specified range( >100% RH) the system will limit the value to 100%.
If measurement of Relative Humidity Sensor is below specified range while the dehumidification mode using RH sensor is
enabled, the system will set an alarm. The system will clear the alarm if Relative Humidity sensor measurement is detected
in specified operating range OR dehumidification mode using RH sensor is disabled.
Check sensor and wiring.
77 ALARM DISCHARGE AIR TEMP SENSOR RT6
if measurement of the discharge air temperature sensor is out of specified range (including open / short detection, the
alarm will be activated. alarm will automatically clear once in range condition is detected.
Check sensor and wiring.
