What is a Millivolt Thermostat?

The thermostat is a device designed to maintain the room temperature at the desired set point and is part of the heating and cooling system. There are three main types of thermostat systems used today. It is a low voltage, line voltage, and millivolt thermostat system.

Millivolt thermostats use very low voltages, 750 mV (0.75 V), and do not require a step-down transformer. The reason is simple; They are not part of the cabling system. Thermostats have a special built-in thermopile generator that generates direct current electricity and powers the device.

Since we are going to talk more about millivolt thermostats, let’s start by explaining what a millivolt thermostat system is. The millivolt system requires a special type of thermostat, and it will not work with a standard low voltage thermostat type. Their use is not common nowadays, and they are mainly direct or top vent wall heaters, gravity wall heaters, direct vent wall heaters for mobile homes, or gas heaters that do not use electricity because they do not. Having a blower fan is mostly used for space heating or space heating.

Now, explaining this, we can focus on millivolt thermostats. If you have a millivolt power system installed in your home, then you must use a millivolt thermostat.
