We have the Carrier Comfort zone II system with 4 zones. Unfortunately, there is no wifi thermostat available for this system. I was wondering if there are other 4 zone controller systems available now that would work with the existing dampers.
Basically change the electronics - the zone controller, the thermostat and the temperature sensors in the other 3 rooms; and use the existing wiring.
I don't think I would actually do the work myself, but I'd like to research the options first.
