Hello,

it is possible by changing terminals but are you aware this will dumb the system down and not be as efficient?

I did not answer..it was letting you know the efficiency will change...are you ready to change wires

Expert:  BillyHvac replied 1 year ago.

they need to change in the furnace as well as thermostat...just let me know when you are ready

And I apologize for pointing out decreased efficiency..efficiency is the main point of heating and cooling and I like to be sure you know what the options are.

But it sounds like you already knew the system would not get as many miles to the gallon so to speak...so I can instruct on how to make it a regular system instead of high efficiency communicating

Are you ready to change wires??
