tion manual. It may be necessary to replace the auxiliary sensor. Once the error
has been corrected, the error message automatically clears.
SENSOR 2 FAULT
Due to an open or short circuit, the thermostat is unable to read the sensor wired
to S2 and Com. The thermostat stops normal operation if sensor 2 is the only
active room or floor sensor or if a floor maximum temperature has been set.
Check the auxiliary sensor wire for short circuits according to the sensor installa-
tion manual. It may be necessary to replace the auxiliary sensor. Once the error
has been corrected, the error message automatically clears.
SENSOR 3 FAULT
Due to an open or short circuit, the thermostat is unable to read the sensor wired
to S3 and Com. The thermostat stops normal operation if sensor 3 is the only
active room sensor or if a floor maximum temperature has been set.

tion manual. It may be necessary to replace the auxiliary sensor. Once the error
has been corrected, the error message automatically clears.
