I have a EWC BMPlus 3000 rev B Ultra Zone Control system with a Comfort Aire 2 stage Geothermal. My problem is my electric bill is way high. I was told by the tech that my control panel will light Y1 when 1st stage heating is being used and Y2 when the 2nd stage is being used, then finally EM when emergency heat is needed. My system is going from Y1 then straight to Emergency heat after about 30 minutes. Is there anything I can do to fix this?
I have turned off my emergency heat breaker, is that ok?
