We are in the midst of a remodel and a contractor (not an electrician or hvac tech) unhooked my Evolution controller in order to move it. He re-wired it using the color-coded wires but it is not showing power.
When he told me about it, I investigated by checking the breakers on my electrical panel as well as on the heat pump unit. One of the two on the unit was showing red/orange so I flipped it. Still no power in the thermostat.
We then re-opened the thermostat to make sure that the wiring looked correct. It all looked normal to me (but I really don't know anything about it).
I also took out the filter to make sure something hadn't gotten in it, but it looked good and I had just changed it last Thursday.
It is after hours and a service tech cannot get here until tomorrow afternoon. I think it might just be a simple 're-set' type of issue (or at least I'm hoping).
Any suggestions? Husband is out of town and the kids are already compaining that it's cold. Ugh!
