Line voltage thermostats are designed to directly control electric heaters, such as baseboard heaters, by switching the main power on and off to the heater. It is important to select an appropriate thermostat that can handle the rating of the heater that will be controlled. You will need to know the voltage and amperage rating of the electric heater. If you have any questions or concerns about selecting the correct thermostat, please call our technical support sales department for help at the number listed above.
