Welcome to the forums.

Turn power off to air handler before messing with the wiring.

We have a problem here. Your White Rodgers stat is showing a B and an O connection. That's telling me that you may have a zoned system in your house. We need confirmation of that. The Honeywell stat you are showing will probably not work there.

Thank you, I’m not sure about if its zoned system or not. By the way, how could tell if its zoned system or not?
also, what type of thermostat or model do you think will fit into my system?

thank you,
