A surface-mounted thermostat for electric floor heating systems, compatible with both 120V and 240V heating cables. The unit operates through a simple on/off switch and includes a built-in Class A GFCI with indicator light, along with a floor temperature sensor. Up to two heating cables can be connected simultaneously, provided the combined load does not exceed 15 amps. For installations exceeding that threshold, a compatible power module can be added to extend capacity while maintaining a single point of control. Installation requires a single gang, deep electrical box — a double gang box with a single gang mud ring is recommended to allow adequate room for wiring. Heating cable leads must be wired in parallel in accordance with applicable electrical and building codes. For multi-cable systems over 15 amps, either additional thermostats or supplemental power modules are required.
