If you have a conventional system installed, your thermostat will ask about the fuel source for your heat and how that heat is delivered. The Nest thermostat uses this information to determine how to control your heating and cooling system.

Type of heating
How to tell what kind of heating you have
- Choose O or B
- The only way to tell for sure if the wire is O or B is to check your heat pump’s manual. Look it up online or contact the manufacturer.
- Most systems have an O wire, so O is a good choice if you can’t tell.
Note: If you choose I Don’t Know, your thermostat will automatically select O.
- Test your system
Don’t worry if you make the wrong selection. Your Nest thermostat will ask you to run a system test at the end of setup. Don’t skip this important step and follow the instructions closely.
- You’ll know that you’ve chosen the right O or B wire if your system behaves normally during the test.
- You’ve chosen the wrong wire if your system heats during the cooling test, or cools during the heating test. If you have only heat or only cooling, and you’ve chosen the wrong wire, then your system won’t heat or cool during the test.
- Change the setting if needed
- If you need to change the O/B wire setting, go back and change the O/B wire setting with your thermostat in SettingsEquipmentHeat Pump.
