The multiple thermostats are wired to a single control panel that is placed within the ductwork of the air system.  The thermostats read the temperature. They shut or close the dampers according to the temperatures that you have indicated on the thermostat’s settings.

3.  How many thermostats do you need?

If you have high voltage heating you may need a higher number of thermostats but for a standard spacing, you can use one, two or utmost three thermostats.

Factors to Consider when Shopping for Smart Thermostat for Multiple Zones

a) Remote sensors

Remote sensors make it possible for the thermostat to track the occupancy of the zones and effectively adjust the temperatures accordingly. They are important for the effectiveness of the unit when it comes to energy conservation. A built-in sensor works just as well as an integrated sensor.

b) Features

The features on the model you are buying should offer you the utmost efficiency and, most importantly, energy consumption. The home/away/sleep feature is crucial to energy conservation because it ensures that the unit is off when the space is unoccupied and on when occupied. Other features like geofencing make the unit more intuitive to you enabling you to have control of your environment at all times. It also helps in energy conservation as it will dial down when it senses you are out of a certain range like 750 feet away from the building. Choose a model that provides you with features that are convenient for you.

c) Algorithms

Algorithms are important because they help the thermostat to learn your habits and usage patterns and automatically adjust to create a comfortable environment. They use the algorithms to schedule temperature changes depending on the season and also on the weather data they retrieve from the internet. Find a thermostat that has advanced algorithms to reduce manual manipulation of the unit every time you need to implement temperature changes.

d) Installation

Installation can be quite challenging for people who have no prior electrical experience. But it doesn’t have to be if you choose a unit that has a clear and accurate instruction manual. Better yet find one that has illustrations to make it easier for you and also for any professional you decide to hire. The best smart thermostat comes with detailed and accurate manual/guides and also all the components needed for a successful installation. In cases where a component is not offered, they indicate this and make sure that it’s a component that is easily available from a hardware shop.

e) Design
