CT41A HEATING/COOLING THERMOSTAT
7 RECALIBRATE THERMOMETER
If the thermostat setpoint and the thermometer reading
do not agree, the thermometer may need recalibration.
Follow this procedure:
Remove thermostat cover.
Set the cover on a table near an accurate
thermometer.
After allowing five or ten minutes for stabilization,
compare the readings.
If the readings are the same, replace the cover and
put the system into operation.
If the readings are different, insert a hex head wrench
into the thermostat shaft and turn it until the
thermometers have the same reading. See Fig. 8.
Replace cover and put the system into operation.
