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 Wi-Fi Smart 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’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 maybe 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.
