I am looking to purchase and install an ecobee 3 thermostat in the home I recently purchased. There is just a basic thermostat that uses a battery.
The wiring is confusing me a little bit. I am unsure whether or not I will be able to install the ecobee with my set up. Any advise would be wonderful.
Thanks in advance.
I have a gas furnace Carrier Model CNPVP. Currently connected is my forced air heating system and central air conditioning system.
I have attached images of the circuit board wiring as well as the thermostat wiring. Will I need to install the PEK or rewire my system for it to work?
