Detroit Radiant TH-DSP3Z Three Zone Controller: on and off control with a timer

The Detroit Radiant TH-DSP3Z Three Zone Controller is an on and off control for three zones, or groups, of heaters. It fits Detroit Radiant DSC overhead gas patio heaters and DSR and DSRF gas tube heaters. It works with single or two stage heaters, meaning heaters with one or two heat settings. The timer lets you choose a run time of 30 minutes, 1 hour or 2 hours. The buttons light up in color. Detroit Radiant builds these controls for its own heaters, so the wiring and voltages match.

The controller needs a 24 volt common connection from one of the heaters to supply its power. A faceplate and a heavy duty junction box, which holds the wiring connections, come with it. Choose this version for a setup with three heater zones. Only need two zones? See the Detroit Radiant TH-DSP2Z Two Zone Controller. The Detroit Radiant TH-DSP3Z Three Zone Controller ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
