In operation, a circuit is completed through the bimetal
heater as the low voltage room thermostat closes its
contacts. In approximately 45 seconds, the warping ac-
tion of the heater closes the line voltage snap-switch to
energize the heating load. When the thermostat opens
its contacts, the bimetal heater cools for approximately
45 seconds before the line voltage switch opens to de-
energize the heating load.

All wiring should be done in accordance with local and national electrical codes and ordinances.

All wiring should be performed
exactly as shown.
As the thermostat closes its contacts, each separate heat-
ing load will be “sequenced on” in intervals of 45 seconds.
When the thermostat is satisfied, each separate load
will be “sequenced off” in intervals of about 45 seconds.
