Faults
ID TEMP SENSOR HIGH
Fault becomes active when main thermistor (P102 or RT1) reads > 100°F.
Fault is cleared when temperature <= 99°F.
When this fault occurs, the thermostat uses the temperature reading from the
temperature/humidity sensor as the space temperature.
ID TEMP SENSOR LOW
Fault becomes active when main thermistor (P102 or RT1) reads < 39°F.
Fault is cleared when temperature >= 4°F.
When this fault occurs, the thermostat uses the temperature reading from the
temperature/humidity sensor as the space temperature.
REMOTE SENSOR HIGH
Remote temperature > 122°F; only flagged if remote sensor set to use as
indoor temperature (REMOTE SENSOR setting set to INDOOR or AVERAGE)
REMOTE SENSOR LOW
Remote temperature = 0°F; only flagged if remote sensor set to use as indoor
temperature (REMOTE SENSOR setting set to INDOOR or AVERAGE)
ID TEMP RANGE HIGH
If the mode is cooling (Cool or Auto operating in Cool), the space temperature
is greater than the cool setpoint plus the Maximum Setpoint Error and this
condition exists for the number of minutes specified by the INDOOR TEMP
FAULT INHIBIT time.
ID TEMP RANGE LOW
If the mode is heating (
HEAT,
EHEAT
or
AUTO
operating in
HEAT
), the space
temperature is less than the heat setpoint minus the Maximum Setpoint Error
and this condition exists for the number of minutes specified by the INDOOR
TEMP FAULT INHIBIT time.
