Servicing The Thermostat
Cycle Rate Adjustment
The equipment should cycle on and off just
enough to keep the room temperature close to
the temperature lever settings.
If the thermostat seems to cycle the heating
system too fast or too slow, adjust the cycle
rate by moving the anticipator setting lever one
indicator mark at a time (Fig. 6). Observe the
heating system operation after each adjust-
ment.
NOTE: Most hot water systems require a
setting of 1.2A.
Thermometer Adjustment
The thermometer has been accurately
calibrated at the factory and should only need
adjustment if it was mishandled.
If the set point lever and the thermometer
reading do not agree, follow the procedure on
the next page.
