The faults and system events display in the banner while fault
condition exists. You can see a history of the faults and system
events in WIFIStat mobile app under Alerts. The history is
comprised of the 5 most recent logged items, with the most recent
event being listed at the top.
Table 10 — Fault and System Events
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.
Fault becomes active when main thermistor (P102 or RT1) reads < 39°F.
Fault is cleared when temperature >= 40°F.
When this fault occurs, the thermostat uses the temperature reading from
the temperature/humidity sensor as the space temperature.
Remote temperature > 122°F; only flagged if remote sensor set to use as
indoor temperature (REMOTE SENSOR setting set to INDOOR or
AVERAGE)
Remote temperature = 0°F; only flagged if remote sensor set to use as
indoor temperature (REMOTE SENSOR setting set to INDOOR or
AVERAGE)
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.
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.
