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.

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.

Can you install multiple thermostats?

Yes, it is perfectly possible to use multiple Thermostats in the same home whenever there is more than one heating circuit (e.g. ground floor and first floor). You will need to install a complete Thermostat (Thermostat + Relay) for each heating zone.

Why does my house 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.

Can you put 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.

Can you turn a single zone HVAC to dual?

The good news is that you can add zones to your existing system, even if you just have a single air handler or furnace connected to a single compressor or heat pump.

How do you install a 2 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 many thermostats should a house have?

Most homes, including multi-story houses, have just one thermostat that controls the temperature throughout. If you own a multi-story home, you should have a thermostat on each floor to effectively control the temperature and save money.

Do I need 2 thermostats for 2 zones?

If you currently have two thermostats controlling two zones you will want two Nest thermostats. You do not need to upgrade them both at the same time.

What is a dual zone thermostat?

A thermostat with multiple sensors across the room accurately reads the temperature. It is connected to a damper attached to the room vents. The damper for each room can open or close individually.

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.

How do you wire a multi zone heating system?

Quote from the video:
Quote from Youtube video: All neutrals so neutral for both heat links. And the pump terminal too same with earth's obviously all earths from heat links in the pump will go together last three connections on the wiring.

Can you have 2 thermostats on one furnace?

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.

How do you split HVAC zones?

Quote from the video:
Quote from Youtube video: Now if we had done those motorized dampers i was talking about i probably would have to cut into this soffit right here and into this ductwork. And put one damper over here.

Is multi zone HVAC worth it?

The benefits of multi-zone HVAC include: Energy efficiency: Be more efficient with your energy spending when you have a multi-zone system. You can adjust the temperature to be more efficient or turn off the HVAC completely in zones that cover unused parts of your home.

Can I cool and heat different rooms in my home simultaneously?

With a zoning system, you can heat and cool different rooms independently, making it a better option than having just a traditional HVAC system to address your heating and cooling needs.

How does a multi zone HVAC system work?

A zoned HVAC system divides your home into multiple zones, each controlled by its own thermostat. This allows you to set each room to the ideal temperature for you, instead of having to heat or cool the entire home to just one temperature.

What is a dump zone in a zoned air system?

Dump zone – a room or rooms where the duct does not have a damper and will receive air flow any time the hvac system is running.

What is the purpose of the Zone 1 master thermostat?

What is the purpose of the zone 1 (master) thermostat in the basic zone control system? Determines the operational mode of the equipment.

Are dampers bad for HVAC?

If you’re thinking, “Hey, closing off my air supply dampers might also increase static pressure,” you’d be right! A fully or partially closed damper pushes back against the air being forced through the system by the blower fan. It increases air resistance inside your ductwork.
