Detroit Radiant TH-109 Two Stage Rain Tight Thermostat: high and low heat control for damp spaces

The Detroit Radiant TH-109 Two Stage Rain Tight Thermostat is a temperature control for the DSCD patio heater and the DSR and DSRF tube heaters. Two stage means it runs the heater on high, then switches to low as the space warms. You can set the temperature from 40 to 100 degrees F. Its rain tight enclosure protects the control in spots with heavy moisture. Detroit Radiant builds these controls for its own heaters, so the wiring and voltages match.

Pair this thermostat with a compatible two stage heater to control both heat settings. Need a wider temperature range? See the Detroit Radiant TH-200 Two Stage Rain Tight Thermostat, with a range of 30 to 110 degrees F. The Detroit Radiant TH-109 Two Stage Rain Tight Thermostat ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
