Detroit Radiant TH-DSTS1 Two Stage Controller: one knob for high or low patio heat

The Detroit Radiant TH-DSTS1 Two Stage Controller is a wall controller for one zone of two stage heaters. That means you can choose high or low heat for the area it controls. It has one illuminated knob and fits the Detroit Radiant DSCD two stage patio heater, along with the DSR and DSRF tube heaters. Detroit Radiant builds these controls for its own heaters, so the wiring and voltages match.

The controller needs a 24 volt common connection to supply power. To run several DSR or DSRF tube heaters from one controller, you need a relay kit for each heater and a transformer. A faceplate and heavy duty junction box come with the controller. Need separate controls for two areas? See the Detroit Radiant TH-DSTS2 Two Zone Two Stage Controller. The Detroit Radiant TH-DSTS1 Two Stage Controller ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
