What is a line voltage thermostat?

A line voltage thermostat is a type of thermostat which is normally used with baseboard or radiant heating systems, such as the Honeywell TL8230A1003. It is uncommon for a line voltage thermostat to be for cooling, although these are available (see the Honeywell T651A3018 line voltage thermostat) but a line voltage unit is only to be used for one or the other, heating or cooling. Normally line voltage thermostats use 240 volts of power, but there are occasional older line voltage models which use 120 volts. The voltage power is connected to the heater directly through the line voltage thermostat causing it to turn on or off through thick wires. These thermostats have to carry the full current drawn by the heater. Line voltage thermostats are not to be confused with low voltage thermostats or used with gas heating systems. TRYING TO CONNECT THE WRONG THERMOSTAT CAN CAUSE FIRES AND OTHER ACCIDENTS, SO USE CAUTION AND BE SURE YOU HAVE THE CORRECT SYSTEM FOR YOUR LINE VOLTAGE THERMOSTAT.
