Honeywell T5


Before you purchase the Honeywell Home T5 Wi-Fi Thermostat, please make sure that your heating and cooling system(s) are compatible. You can easily check whether this thermostat is co compatible by visiting Honeywell Home's Wiring Compatibility page.

C-wire is required

A C-wire (also referred to as a common wire) is a low voltage power wire that many modern thermostats require for their features to work. This Honeywell Home T5 Wi-Fi Thermostat requires a C-wire 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 that you have a C-wire and that your HVAC system is compatible with Honeywell Home’s thermostat. To determine if you have a C-wire, please remove your old thermostat's cover plate. You should see several wire terminals labeled with letters. If a wire is connected to the “C” terminal, you have a C-wire.

If you do not have a C-wire on your existing thermostat, you may be able to substitute an extra wire or the “G” wire for the C-wire. You can also hire an HVAC contractor to help you install the C-wire and the thermostat.

**This thermostat is not compatible with electric baseboard heating systems.**
