Detroit Radiant SWPD-4H Four Hour Timer: set your heaters to shut off automatically

The Detroit Radiant SWPD-4H Four Hour Timer is a wall timer that runs your heaters for up to four hours. Turn the knob to set the time, and the heaters shut off by themselves when it ends. It fits any Detroit Radiant gas or electric heater controlled from a wall box. The timer has a white wall plate and knob. Detroit Radiant builds these controls for its own heaters, so the wiring and voltages match.

For electric heaters, an electrician checks whether the timer can handle the heater’s electrical load. If needed, they add a contactor, a separate switch that handles power to the heater. Need a lockable outdoor box? See the Detroit Radiant WEP-TS Weatherproof Timer Enclosure. The Detroit Radiant SWPD-4H Four Hour Timer ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
