Storefront Attributes

• Energy Star: Yes
• Water Sense: No
• Media Feature: kBEI5_SbDLU
• Media Feature Markdown: ### Before You Buy: Check if Your Equipment is Compatible REQUIRED: A C-wire (common wire) is needed for 24 VAC power. To determine if you have a C-wire, please consult Honeywell Home’s [**compatibility checker**](https://www.honeywellhome.com/en/general-pages/wi-fi-programmable-thermostat-home-compatibility{openNewTab}). If you do not have a C-wire, then a C-wire adapter is provided. You can also hire an HVAC contractor to help you install the C-wire and the thermostat. ### What's a C-Wire? A C-wire (common wire) is a low voltage power wire that many modern thermostats require for their features to work. Many older homes don’t have a C-wire because mercury and battery-powered thermostats didn’t require one. Therefore, it is important that you make sure your HVAC system is compatible with this Honeywell Home thermostat. If you currently have a Honeywell Home T-Series thermostat, your wiring may already be set to install the Honeywell Home T9. Thanks to their shared wall mount, replacing an old T-Series thermostat with a new T9 is as simple as snap-off, snap-on. If you don't have a C-wire, there's even an included adapter to cover that. **This thermostat is not compatible with electric baseboard heating systems.**
