Your thermostat is a key part of controlling your HVAC system and managing your home’s temperature. When looking to upgrade your thermostat to a newer model, such as a smart thermostat or simply a newer one, it’s important to know how thermostat communication works.
Thermostat Communication: The Two Main Types
In general, thermostats come in two different types as it relates to communication with your HVAC system. These is the more-common electric type and the less-common electromechanical thermostat.
- Electric Thermostat: The most common type of thermostat, electric thermostats make use of sensors to detect temperature changes and then turn the HVAC system on or off as needed. Electric thermostats have features that range from simple to programmable, including smart thermostats that you can program from your smartphone that also learn your daily habits to keep home temperatures precisely where you need them.
- Electromechanical Thermostat: This type of thermostat is far less common and is only really seen in older homes. An older type of heating and cooling technology, these thermostats rely on a strip or a coil. Temperature changes cause the coil to move, in turn moving a mercury vial that signals the HVAC system to turn on or off.
Tips for Upgrading to a Smart Thermostat
Before upgrading to the latest smart thermostat to get the best thermostat communication, it’s important to know what will work with your existing HVAC system. Important facts include your HVAC power source (gas, heat, or other source), your voltage needs, whether you have single or multistage units, whether they’re ductless or not, and your HVAC system’s age. A professional can help you find a compatible smart thermostat to fit your needs and deliver great thermostat communication to your home.
