Detroit Radiant TH-T1-4H Toggle Timer Controller: automatic shutoff after up to four hours

The Detroit Radiant TH-T1-4H Toggle Timer Controller is a toggle switch control with a four hour timer for your heaters. Flip it on, and it shuts the heaters off after up to four hours. It controls one zone, meaning one group of heaters operated together. It is for single stage heaters, which have one heat setting. It fits Detroit Radiant DSC overhead gas patio heaters and DSR and DSRF gas tube heaters. Detroit Radiant builds these controls for its own heaters, so the wiring and voltages match.

The controller includes its own transformer, the part that supplies power to the controls. One controller runs up to two DSCS patio heaters or up to seven DSR or DSRF tube heaters. Each tube heater must have a relay kit to work with this controller. Need two stage control? See the Detroit Radiant TH-T2-4H Two Stage Toggle Timer Controller. The Detroit Radiant TH-T1-4H Toggle Timer Controller ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
