EWC Controls Forum

Thank you Erik...I did talk to a tech support guy from EWC this morning too. As far as the EWC-ST control panels go, I have found probably 15 or so thermostats that will work for the master thermostat with this system. It really threw me off reading that only a select 4 or so stats would work ...

I have the EWC-ST-3C Zone control panel with 3 Zones, forced air/furnace and A/C...single stage. I know the topic has come up alot and I understand the separate O and B terminal for the master thermostat so...my question is will Radio Thermostats CT-22, CT-30, or CT-80 work for all 3 of my zones ...
