Operating Instructions
Once installed, the TSH1TX thermostat allows you to control the temperature output of your TSH Specialty Heater. The control type is a button control, typically a rotary knob.
- Turning On/Off: Rotate the thermostat knob to the desired temperature setting. Turning the knob fully counter-clockwise to the "OFF" position will typically turn off the heating element.
- Adjusting Temperature: Rotate the knob clockwise to increase the desired temperature and counter-clockwise to decrease it. The heater will cycle on and off to maintain the set temperature.
- Temperature Range: The specific temperature range will be marked on the thermostat knob or the heater's control panel.
