Check first if you have

  • Phone or voice control
  • Line-voltage baseboard heat

What it controls

The Resideo T6 Pro 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.

Check your wall for a C terminal: the listing doesn't say whether it needs a C wire. The C wire guide covers adapters.

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: 2 Heat / 1 Cool. A second-stage wire (W2 or Y2) at your old thermostat needs matching support here. Single- and two-stage systems.

Schedule: Programmable. Program sleep and away setbacks once and it runs them every week.

Not sure of your wiring? The wiring checker reads your system from the terminal letters and checks it against this model's statements.

Also on the listing: dimensions of 4 x 4 x 1 inches and a weight of 2 ounces.
