Servicing The Thermostat

Thermometer Adjustment

The thermometer has been accurately

calibrated at the factory and should only

need adjustment if it has been dropped or

mishandled.

If the setpoint lever and the thermostat

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

thermometer of known accuracy.

Allow at least five minutes for cover ther-

mometer to sense area temperature, then

compare the readings. Be careful not to touch

thermometer or breathe on it.

If the readings are the same, replace cover

and put the system into operation.

If the readings are different, insert a small

screwdriver in the thermometer slot, shown in

Fig. 6, and turn it until both thermometers read

the same.

Replace thermostat cover and put the

system into operation.
