Heat-Only Low Voltage Wall Thermostats

These units regulate heat-only applications.

Low-voltage thermostats do not directly power a connected HVAC system, instead sending a signal to the HVAC system's control board which then regulates the temperature.

Room thermostats, also known as wall thermostats, sense the air temperature in order to  regulate and maintain a set temperature for a residential, commercial, or industrial space bu switching the heating or cooling system on or off as the temperature changes.  Typically, these controls mount on an interior wall, though some units can plug into a wall outlet.
