Multi-zone Thermostat

Most homes have multiple zones or spaces, such as the living room, bedroom, and kitchen. All these spaces need to be temperature-controlled, but not simultaneously. So, at this juncture, a multi-zone thermostat comes into play. Using a multi-zone system has many advantages. You can keep each area at the right temperature when needed, avoid wasting energy, and save money on utility bills. In this article, we will dive deep into the topic. Let’s get started!

What is a Multi-zone Thermostat?

A multi-zone thermostat controls the temperature in our home. Usually, homes are divided into different zones with individual temperature settings. Apart from maintaining a constant temperature in your home, multi-zone thermostats let you adjust heating or cooling temperatures to specific areas. You can make this happen by integrating multiple thermostats with an app or motorized dampers that coordinate with the HVAC system.

Working of a Multi-zone Thermostat

The core of a multi-zone system lies in its ability to regulate airflow with dampers installed in the ductwork. If a particular zone requires heating or cooling, the thermostat in that zone signals the system to adjust the damper, allowing conditioned air to flow into that space. Also, the zones that do not require any adjustments have their dampers closed or partially closed, which reduces utility bills.

Homeowners can easily manage settings from smartphones or tablets, even when away from home. Most advanced multi-zone thermostats have Wi-Fi capabilities, smart sensors, and compatibility with voice-controlled assistants like Alexa, Google Assistant, or Apple HomeKit.

Benefits of a Multi-zone Thermostat

• Better Comfort: Every family has its temperature preferences, so choosing a multi-zone thermostat can let you enjoy the preferred temperature in your personal space.
• Energy-Efficient: Heating or cooling only the occupied areas of your home, rather than unoccupied rooms, will dramatically reduce your energy bills.
• Advanced Control: With advanced technology, we can seamlessly control the HVAC system’s temperatures and create schedules according to your availability.
• Increased Property Value: Technologically advanced HVAC systems can improve a home’s aesthetics and resale value in the present market.
• Less Wear and Tear: Because the system doesn’t have to work as hard to heat or cool the whole house evenly, it can help the HVAC parts last longer.

Points to Consider Before Installing a Multi-zone Thermostat

• Compatibility: Some HVAC systems are not compatible with multi-zone thermostats. So, you must consult your local HVAC contractor to know which thermostat suits your system best.
• Installation Costs: The initial cost can be higher due to the dampers, thermostats, and other control equipment, but the investment is worth it.
• Professional Installation: Some thermostats can be installed DIY. However, due to its complexity, a professional HVAC expert is needed to install a multi-zone thermostat.

How to Get Multi-zone Temperature Control?

Depending on your HVAC system type, you can convert your home into multi-zone temperature control in two possible ways: system-based and sensor-based zoning. Systems like window AC and ductless mini-split systems have thermostats and work in zones. You can save energy by upgrading to a smart thermostat and controlling it from anywhere. Central HVAC systems like furnaces, boilers, and heat pumps do not work in zones, and they have only 1 or 2 thermostats to control the whole home. So, by choosing a multi-zone smart thermostat, you can create multiple heating and cooling zones.

1. System-Based Zoning

System-based zoning is a simple concept that can be understood easily. In this setup, your home has different heaters or AC units that can be controlled separately with individual thermostats, creating their own zones. This is common with electric heating or cooling systems. It means you’ll have more than one thermostat — usually one for each room or zone. This is one of the best ways to save energy because you can control individual zones according to your comfort. If you upgrade to smart thermostats, you can quickly control them from your phone and see energy savings.

2. Sensor-Based Zoning

With sensor-based zoning, you don’t need a thermostat in every room. Instead, you use sensors to help control the temperature in different areas. This works well if you have one main thermostat for the whole house. However, it takes longer to heat or cool the space if you have a thermostat in the living area. This can make smaller spaces, like bedrooms, colder or hotter while you are trying to manage the temperature in the living room.

With sensor-based zoning, you use a smart thermostat with sensors placed in different rooms. These sensors check the temperature in each area and help keep every room comfortable, so you don’t have stuffy bedrooms.

Conclusion

A multi-zone thermostat is an efficient way to make your home comfortable and energy efficient. Irrespective of the zoning type you choose, you can control the temperature of each area of your home according to your comfort level. This can help you save on energy bills and contribute to a long-lasting HVAC system. So, if you are ready to upgrade to a multi-zone thermostat, we are at your beck and call!
