What voltage does a thermostat use?
24 volts
The most common type of voltage from a central heating and/or cooling system is 24 volts (24Vac). The old thermostat may say somewhere on the thermostat that it is for 24 volt (24Vac) or maximum 30 volts (30Vac). If you see 120 Vac or 240 Vac on the thermostat, a low voltage thermostat will NOT work with your system.

How do I change my high voltage thermostat to low voltage?
The basic approach is to buy a switching relay that is operated by the low-voltage thermostat and that in turn turns on the 120VAC or 240VAC heaters. You replace the line voltage thermostat with the switching relay, then add low voltage wire from a transformer to power the Nest or other low-voltage thermostat.
What is the advantage of using a line voltage thermostat over a low voltage thermostat?
Line voltage thermostats deliver electricity directly to heaters. So, they handle more power than low voltage thermostats that control central HVAC systems like a gas furnace. They work by measuring room temperature and controlling power delivery to maintain a setpoint (the temperature you set your thermostat).

It is standard in lighting, while “low voltage (12v or 24v) lighting” is used less commonly. Line voltage lighting systems typically use 120v or 277v to supply power to lighting fixtures. Line voltage lighting systems do not require transformers to power lighting fixtures in many different applications.
