Wall Mounted Residential and Commercial Room Thermostat

The WT-121 and WT-122 Room Thermostats are designed to control individual heaters or may be used with an external contactor. The WT-121 provides heat control with a SPST snap action switch (open on rise) for breaking one line of the power source. The WT-122 also is a heat control but uses a DPST snap action switch and will break both lines of the power source.

Both models include heat anticipators—assuring closer and more even temperature regulation.

WARNING: Hazard of Fire.

The WT thermostats are designed for temperature control service only. Because they are not fail-safe, they should not be used for temperature limiting duty.
