W, W1, W2: Just like the Y wire, the W wire(s) control the heating aspect of your system. O, B, O/B: These wires are responsible for switching the changeover valve in a heat pump system. The O wire reverses the valve from heating to cooling, and the B wire switches the valve from cooling to heating.

29 sie 2022 · If you identified an O, B, or O/B wire connecting to the O/B terminal in the previous step and it has a separate W wire, place it into the W2 terminal. Connect the W wire to the W terminal if you don’t have a wire connected to the O/B terminal. Check your thermostat wiring compatibility.
White wires are for heating. You will find them in gas furnace thermostats, for example, but won’t find them in air conditioner thermostats. W wires go directly to the source of heating; that may be a furnace (gas, electric, oil, you name it) or heat pumps (mini-split heat pumps included). W2 is designated for two-stage heating.
