Honeywell t8095a-191108aj User Manual

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, use the following procedure:

1. Remove thermostat cover and open the

flip-up cover.

2. Set the thermostat cover on a table near a

thermometer of known accuracy.

3. Allow at least five minutes for cover

thermometer to sense area temperature, then
compare the readings. Be careful not to touch
thermometer or breathe on it.

4. If the readings are the same, replace the

cover and put the system into operation.

5. If the readings are different, insert a small

screwdriver in the thermometer slot, see Fig. 7,
and turn it until both thermometers read the
same.

6. Replace the thermostat cover and put the

system into operation.
