The quick answer is yes: if both of your thermostats are the “dry contact” type, meaning they’re a simple switch with no voltage applied, then they can be wired in parallel and connected to your millivolt gas valve. When either one or both together calls for heat the heater would turn on.

Can I wire two thermostats in parallel?

You may not be able to wire two thermostats exactly in parallel, but using multiple wall thermostats or temperature sensors to control one individual heating or cooling zone is easier than you might think.

What type of thermostat is required on a millivolt room heater?





Millivolt thermostats use very low voltage thermostats (usually 750 millivolts).

Can I install two thermostats?

The question is whether it is possible to use two thermostats to control one Zone. Yes, in principle, you can use two thermostats to control one HVAC zone. If correctly installed, set, and used you can actually save on your electricity bill. You can also connect more than one thermostat to a single HVAC unit.

Can you add a thermostat to a gas wall heater?

There’s actually a lot of thermostats that can be attached to the actual heater body. They’re the thermostats you see near the floor on the lower part of the wall. Just thinking about it, there must be an easier way to adjust the thermostat without having to bend over. That’s where thermostats on the wall are helpful.

How do two thermostats work together?

When multiple thermostats control one system, the house is divided into zones using dampers in the ductwork throughout the house. When one zone needs heating or cooling, the damper for the ductwork in that zone opens, guiding the warm or cool air to that zone.

How does a furnace with two thermostats work?





Each zone has its own thermostat that controls the heating and cooling operation in that area. The dampers and thermostats are connected to a central control panel that is also connected to the HVAC unit. This allows the unit to respond to requests from multiple thermostats.

Is there a millivolt thermostat?

Millivolt systems are regulated using thermostats specifically designed for the system, commonly known as ‘millivolt thermostats’. In homes across the USA, there are currently 3 types of heating systems in use. A thermostat is always designed to cater to one type of system, and it can not be used interchangeably.

How do you wire a millivolt thermostat?

How do I Wire a Honeywell Millivolt Thermostat?

  1. Turn off the electricity to your heating unit, such as a furnace or boiler.
  2. Connect one thermostat wire to one screw terminal on your millivolt thermostat’s wall plate. …
  3. Connect the second thermostat wire to the second screw terminal on your thermostat.

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.

Why do I have 2 thermostats?



Having two thermostats wired to the same HVAC unit allows you to evenly condition your home. With the use of zones, control, and dampers, you can regulate your home from top to bottom. However, installing two can be complicated. Multiple thermostats allow for more accuracy and efficiency.

How do you install a multi zone thermostat?

It can be done in three simple steps:

  1. Replace your existing thermostat with a smart multi zone thermostat (a thermostat with remote sensors).
  2. Purchase external sensors for each room and connect them to your smart thermostat via the app.
  3. Place a sensor in each room you’d like to control as a separate zone.

How do you balance upstairs and downstairs temperature?



Keep the air moving by turning on the fan setting of your home’s thermostat. Turn the fan from “auto” to “on”. The fan will circulate the air continually throughout the home and can help even out temperatures between floors.

How do you regulate heat in a two-story house with one thermostat?

Set the first floor’s thermostat to your desired temperature, and then decrease the temperature setting on your thermostats by two degrees as you go up. Warm air on the first floor will rise and make the upper floors more comfortable.

Why is my upstairs so hot and downstairs cold in the winter?

Cold air is denser than warm air, so it stays on the bottom while warm air rises. That’s why the downstairs can feel so chilly while the upstairs is toasty in the winter. The temperature differential between the upstairs and downstairs in an average two-story home is between 8 to 10 degrees.

Why is my bedroom hotter than the rest of the house?

First, check for these common problems: Dirty air filter—A dirty filter restricts airflow, not letting your home get enough cool air. Closed vents—Closed vents in rooms can cause them to be hotter than other rooms. Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home.

How do I even out the temperature in my house?



Here’s how to maintain an even temperature throughout your home:

  1. Clean the Air Ducts. If you have leaks in your air ducts, cool air won’t make it to every air vent, resulting in uneven cooling. …
  2. Turn On the AC Fan. …
  3. Adjust the Air Vents. …
  4. Check the Insulation. …
  5. Install a Zoned System.

Does closing doors keep house warmer?

Contrary to common belief, closing off a room can actually make your heating less efficient. When interior doors are kept shut, the pressure in the room increases because the flow of air is now blocked.
