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 adjustment.
NOTE: Most hot water systems require a setting
of 1.2A.
