We need to take a look at how the wires connect to the terminal block in the furnace/air handler. Please post a picture.

Hey there,

Sorry for the delay but thanks for these photos.

Based on the wires you provided, you have a dual fuel system. This is sometimes also called a hybrid or packaged system which is a combination of a heat pump for primary heating and cooling, and a furnace (usually gas or oil) that provides a second and/or third stage of heating.

If you have a dual fuel system, you will need to have a trained professional set up your thermostat. It’s important for a professional to assess the requirements for your specific dual fuel configuration since choosing incorrect options for a dual fuel system can result in damage to your system. Please contact a local pro.

Best,

Melba
