How Do You Wire A Line Voltage Thermostat?
Line voltage thermostats control electric baseboard heat and other electric heaters. The thermostat cycles these heaters on and off to maintain the set temperature in the building. Line voltage thermostats work the same way as their low voltage counterparts do except for one key factor. Line voltage thermostats use 110 volts of power (regular house current), while low voltage thermostats use 24 volts of power. Turn off the power to the circuit that powers the line voltage thermostat. Usually the thermostat is provided power from the heater, so the circuit breaker will probably be labeled for the heater it serves. Remove the thermostat cover and make the electrical connections. The black wire coming from the heater will connect to the red wire on the thermostat. The white or red wire coming from the heater will connect to the black wire on the thermostat. These connections are made with wire nuts. The ground (green) wire coming from the heater will be connected to the ground screw on th
