The WR series has been discontinued. Please contact our Temperature Engineering department for a viable replacement.
The WR Series Room Thermostats are designed to directly control individual heaters or, by using an
external contactor, can control several heaters. The WR-90 is particularly useful for maintaining
lower temperatures (in garages, warehouses, etc.) and avoiding unnecessary heating costs.
Each design has accuracy and provides long reliable service with a 3° control differential. Both units
are heavy duty, single stage, with a SPST line voltage snap-action switch and are finished with tough,
metallic gray enamel housings.
The WR80-EP room thermostat is designed to control individual heaters directly or by using an
external contactor to control several heaters. It provides accuracy, long and reliable service. The control is
a heavy duty, single stage, SPST line voltage snap-action switch featuring an external, coiled
sensing element and adjustable setpoint knob.
WARNING: Hazard of Fire. The WR thermostats are designed for temperature control service only.
Because they do not fail-safe, they should not be used for temperature limiting duty.
