wiring

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

If a wiring diagram is supplied with the heating equipment, follow those instructions. If none is available, several diagrams are presented on this sheet which show different wiring meth- ods for these Silent Operator relays. Always be sure that the supply voltage agrees with the voltage rating of the Silent Operator relay.
