CALIBRATION ADJUSTMENT
These thermostats have been carefully adjusted at the factory
and should not require re-calibration.
A few degrees difference between the indicator setting of the
thermostat and actual room temperature is not considered
important. If the disagreement is appreciable, however, first
make sure +hat the thermostat is properly located and leveled.
Then, if ’ 'Ubration still seems necessary, proceed as
follows:
These instructions apply for cooling models, with either sealed
mercury or snap-action contacts.
1. Move temperature adjustment lever to a setting about 5°
below room temperature.
2. Remove thermostat cover. Slip standard 7/32" wrench onto
hex
nut
beneath
bimetal,
and,
holding
temperature
adjustment lever stationary, turn hex nut counterclockwise
until mercury shifts to leift end of tube (or until movable
contact closes against magnet on snap-action types.)
3.
R e m o v e wire from terminal on thermostat or wall
mounting plate to take cooling anticipator out of circuit.
4. Replace thermostat cover. Wait 10 minutes for bimetal
temperature to stabilize. Don't stand near thermostat
during this period as your breath and body heat will affect
temperature of bimetal.
5. Move temperature adjustment lever to correspond to actual
room temperature. Then remove thermostat cover.
STANDARD 7/32" WRENCH
6. Slip Standard 7/32" wrench onto hex nut and holding
temperature adjustment lever stationary, turn hex nut
clockwise until mercury just barely shifts to right end of
tube (or until movable contact just moves off of magnet on
snap-action types.)
7. Replace wire removed in step 3. Then replace thermostat
cover and set thermostat to desired temperature.
