How does a millivolt thermostat work?
Millivolt Thermostats
Unlike low-voltage systems, they do not require a step-down transformer and are not connected to the household wiring system. Instead, they are self-powered by a special thermocouple device called a powerpile or thermopile generator that produces direct current (DC) electricity.
How far away should a thermostat be from wall heater?
Better yet, install your thermostat at least 1 stud away from the heater. Moving a thermostat out of the same wall cavity as a heater will help performance.
What is a millivolt furnace?
A millivolt heating system is usually a floor heater or a wall heater that doesn’t use electricity; for example, a gas fireplace or a gas-powered wall heater. Millivolt systems are regulated using thermostats specifically designed for the system, commonly known as ‘millivolt thermostats’.
How do you wire a gas wall thermostat?
There are three screws on a red block the gas valve is located on the bottom left side of the unit. Next take a 1 wire and connect it to the top screw located on the gas valve.
How can I tell if I have a millivolt thermostat?
Determining Your Thermostat Type – YouTube
What is the difference between a millivolt thermostat and a 24 volt thermostat?
A line voltage thermostat needs to be connected to a power supply of fewer than 30 volts, while a millivolt thermostat needs only 0.75 volts and a line voltage thermostat needs 120 to 240 volts. A millivolt thermostat consumes the least amount of energy while the line voltage type consumes the highest.
Where should you not put a thermostat?
Locations to Avoid
- Windows and doors: Don’t place your thermostat near windows or doors that may let in drafts.
- Exterior walls: Likewise, don’t place your thermostat on an exterior wall.
- Supply vents: Placing a thermostat directly above or below a supply register can really confuse the system.

The best place for your thermostat is on an interior wall, away from all the areas we previously discussed (direct sunlight, air vents, your kitchen, hallways, windows and doors). Ideally, it should be placed toward the center of your home.
How do I know if my thermostat is millivolt?
What happens if you wire a thermostat wrong?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
Where do thermostat wires go on furnace?
The white wire underneath your thermostat connects to your heating system. It terminates at your air handler or furnace. The white wire connects to terminal W in industry-standard thermostats.
Can you put a new thermostat on an old furnace?
If you’ve bought a furnace in the last few years, this shouldn’t be a problem. Even if you have a very old furnace, you can still get a smart thermostat installed properly.
What power supply is needed for a millivolt thermostat?
A line voltage thermostat needs to be connected to a power supply of fewer than 30 volts, while a millivolt thermostat needs only 0.75 volts and a line voltage thermostat needs 120 to 240 volts.
Should thermostat be on interior wall?
Should thermostats be on exterior walls?
Avoid placing them on exterior walls, since the temperature of exterior walls fluctuate more. If a thermostat has to be placed on an exterior wall, make sure the back is well insulated to prevent false readings.
Why are thermostats placed in hallways?
Because hallways are generally long and narrow, they have decreased airflow and circulation. This means the hallway temperature often doesn’t reflect the average air temperature of the house as a whole. Placing your thermostat in the hallway means that the hall will be comfortable.
What is the ideal thermostat temperature in winter?
68 degrees Fahrenheit
The ideal thermostat temperature in the winter is 68 degrees Fahrenheit when you’re at home. Energy.gov suggests that 68 degrees is a good room temperature while you’re awake at home but recommends lowering it while you’re asleep or away.
Why is my thermostat not communicating with furnace?
When a furnace is not responding to a thermostat, there is either a problem with the heating unit or the actual thermostat. Lack of power to the thermostat, wrong settings, and outdated software might be to blame, as well as faulty wiring, a tripped breaker, and a dirty furnace filter.
Can I replace my thermostat with any thermostat?
Most replacement thermostats are compatible with all common systems. However, if your system is unique, finding a replacement thermostat may be difficult.
Does R go to RC or RH?
An R wire can go into a Nest Learning Thermostat’s Rc or Rh connector.
Will any thermostat work with any furnace?
Know Your Equipment & Your Wiring
Not all thermostats are compatible with existing HVAC systems, especially smart thermostats! Some thermostats work only with furnaces and air conditioners, for example. Others may be designed to monitor heat pumps or multiple-stage heating and cooling systems.
