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

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.

Using one thermostat and two or more silent operators to “sequence” loads

Figure 5 shows how several Silent Operator relays can be used to “sequence on” separate heating loads. The red and white leads of additional Silent Operator relays should be jumpered as shown. 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.
