Line Voltage Thermostats

A line voltage system uses direct current instead of only 24 volts like the typical thermostat of today's newer homes. This type of thermostat is used in older homes that use direct voltage. The power wires are thicker and they generally run either 120 or 240 volts on direct current.  See our selection of line voltage thermostats below.
