HEAT ANTICIPATION (Figure 1)
This thermostat is equipped with an adjustable heat antici-
pator. Set heater indicator to match the current rating of
the primary control. The heater may be adjusted for cur-
rent ratings from .15 to 1.0 Amps.
Adjustments
Cycles too long — Set adjustable heater to a slightly
lower dial setting (1/2 division).
Cycles too short — Set adjustable heater to a slightly
higher dial setting (1/2 division).
CALIBRATION ADJUSTMENT (Figure 2)
These thermostats have been carefully adjusted at the fac-
tory and should not require re-calibration.
A few degrees difference between the indicator setting of
the thermostat and actual room temperature is not consid-
ered too important. However, if the temperature is much
greater, first make sure that the thermostat is properly locat-
ed and leveled. Then, if re-calibration still seems neces-
sary, proceed as follows:
1. Move temperature adjustment level to a setting about
5° above 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 clockwise until
mercury shifts to right end of tube.
3. Move temperature adjustment lever to lowest setting.
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 the temperature of the bimetal.
5. Move temperature adjustment lever to correspond to
actual room temperature. Then remove thermostat
cover.
6. Slip 7/32" wrench onto hex nut, holding temperature
adjustment lever stationary, turn hex nut counterclock-
wise until mercury just barely shifts to left end of tube.
Then replace cover and set thermostat to desired
temperature.
