Thermometer Adjustment
The thermometer has been accurately cali-
brated at the factory and should only need
adjustment if it has been 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
a thermometer of known accuracy.
• Allow at least five minutes for the cover
thermometer to sense the area tempera-
ture; 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.
