CALIBRATION

THERMOSTAT

These thermostats are accurately calibrated at the

factory. THEY DO NOT HAVE PROVISION FOR FIELD

CALIBRATION.

THERMOMETER

The thermometer in your thermostat has been ac

curately calibrated at the factory. The thermometer

should only need adjustment if It has been dropped or

shifted due to mishandling.

If set point lever and the thermometer reading do not

agree, follow the procedure below.

1. Remove thermostat cover by pulling up from the

bottom of cover until it clears the retaining posts.

2. Set the cover on a table near an accurate ther

mometer.

3. After allowing 5 or 10 minutes for stabilization,

compare the readings. If they are the same, replace cover

and put system into operation. It they are different,

recaiibrate the thermostat thermometer, step 4.

4. Insert a small screwdriver in the thermometer shaft

(Fig. 8) and turn it until the thermometers read the same.

When the thermometer is calibrated, replace cover and

place system into operation.

NOTE: Hand heat will offset the thermometer reading.

After making each adjustment, wait 5 or 10 minutes for

the thermometer to stabilize before comparing. Fig. 8—Thermometer calibration.
