The 7 Best Two Thermostats One Zone

Can I pair two thermostats to work with a single zone system? The answer to this question is yes! What you need is a single thermostat that has support for one or more secondary remote thermostats. If you have more than one thermostat in your home, then you have a zoned system. In zoned systems, each thermostat controls heating and cooling independently in order to heat or cool different areas of the house. Smart Thermostats for multiple zones use a great technology that has your needs covered.

Thermostats in zoned systems can control the same heating and cooling system or each thermostat can control its own system. When multiple thermostats control one system, the house is divided into zones using dumpers in the duct work throughout the house. When one zone needs heating or cooling, the damper for the ductwork in that zone is opened, guiding the warm or cool air to that zone. Zoning with dampers is usually coordinated using zone relay panels. An example of this is the Honeywell Multi-zone thermostat.

System zoning is not only helpful for houses with inconsistent room temperatures but it’s also great for heating or cooling individual bedrooms based on the desired temperature setting. It is also a security solution with the wireless video with doorbell monitor technology. Might you be having a usually empty guest room, then just shut the door and close the damper. Zoning has got you covered.

Benefits of two thermostats for one zone

The HVAC industry has evolved considerably over the past 50 years, with internet connectivity and smart home technology coming into the fold. Smart homes can benefit especially by giving homeowners the ability to set the temperature remotely.

  • A correctly installed system can help you save substantially on your utility bills. You can set more frequently used rooms at a specific temperature that is ideal for living while the less-used rooms set to a lower temperature.
  • The ability to remotely control a room’s temperature with temperature control is very convenient. You can also set the system to work less while you are away thus saving energy and hence lower bills.
  • You can also set up different temperatures for different times of the day using the smart auto-change technology that comes with most of these great devices. This programming feature is available in some of the products in the market.
  • Smart thermostats for multiple zones learn your schedule and preferences, making it easy to be energy efficient by letting the thermostat handle the dropping and raising of your home’s temperature as you come and go. You never have to worry anymore when you have left the AC or heater running all day while you were out, you will appreciate how a smart thermostat will detect your absence.

Algorithms. Some advanced thermostats use algorithmic learning. Over time, they learn your patterns and can, therefore, start setting up schedules according to the pattern they may have detected.


This is basically a virtual perimeter you can establish as a range for your thermostat sensors. It sets up a boundary around your home to detect your presence within the home and when you are away, it automatically dials down the thermostat to save energy.


You might want to find a smart thermostat that is not too ugly or clunky to look at and one that goes well with your home’s general aesthetic. Different thermostats come in a variety of colors; it is therefore up to you to choose wisely.


You need to use the app before purchasing the thermostat to make sure it’s user friendly and well designed. Smart thermostats work in conjunction with smartphone apps that allow them to be integrated into your smart home.

Lastly, you may lookout for a thermostat that is easy to install. Typically, you would reach out for one that you can install by yourself with a step-by-step installation set up guide and photographs also. Most of the thermostats are usually installed using one of two wiring systems. Get one that you are more comfortable with.

There are however a lot of different smart thermostats for multiple zones in the market and each one of them come with its own unique set of features and functionality abilities.

Bottom Line

If used properly, system zoning can help you save money on your energy bills. System zoning can save homeowners up to 30% on a typical heating and cooling bill. This is according to the US department of energy.

Because guest rooms and other seldom-used rooms do not require constant heating and cooling, zoning allows you to save money by running temperature-controlled air to these rooms only when it is necessary. Get ready, it’s time to get zoned up!
