Hello -

I am homeowner.

I have a 3 zone setup in my home. I have single stage gas furnace and A/C. I will be finishing the basement and need a 4th zone. I am planning on replacing the ST-3E with a BMPlus 5000. I am also replacing my thermostats (one at a time) with ecobees.

I do not have a heat ...
