Thermometer adjustment
The thermometer was accurately calibrated
at the factory and should only need adjustment
if it was dropped or mishandled.
If the setpoint lever and the thermometer
reading do not agree, follow the procedure
below.
Remove thermostat cover and open the flip-
up cover.
Set the thermostat cover on a table near the
thermometer of known accuracy.
Allow at least five minutes for the cover
thermometer to sense the area temperature,
then compare the readings. Be careful not to
touch the thermometer or breathe on it.
If the readings are the same, replace the
cover and put the system into operation.
If the readings are different, insert a small
screwdriver in the thermometer slot shown in
Fig. 7, and turn it until both thermometers read
the same.
Replace thermostat cover and put the
system into operation.
