What are thermostat relays and transformers?

A thermostat relay relies on electromagnets to open and close circuits when directed by the thermostat. The thermostat also signals the relay to power on or off the heater. Additionally, relays stop the thermostat from overloading by increasing the wattage capacity.

Transformers can boost or reduce voltage levels between circuits. Connecting more than four relays without a transformer to the same thermostat is not recommended.

What low voltage relays does Stelpro offer?

Stelpro offers the following low voltage relay models:

RE25 and RE30 electronic relays:
