What it controls
The Honeywell Home TH8110R1008 Programmable Thermostat is a programmable. Its listing doesn't spell out which heating and cooling systems it supports, so run the maker's compatibility checker before you buy.
Power is where installs stall: the listing doesn't say whether it needs a C wire. C-wire options.
The listing doesn't state heat pump support; if you have an O/B wire, confirm with the maker before ordering. Heat pump wiring.
Stages, per the maker: 1h/1c. A second-stage wire (W2 or Y2) at your old thermostat needs matching support here. Single- and two-stage systems.
Schedule: 7 day programmable. Program sleep and away setbacks once and it runs them every week.
Power, per the listing: Battery Powered. Battery models often fit old two-wire circuits with no C wire.
