Customer Question

I am trying to trouble shoot our Rheem digital thermostat. I turned the AC off today so that I could open my windows. Now the unit will not come back on. I have never had a manual to this thermostat, and I am clueless as to how to work it. maybe our HVAC is going bad, but I just don't know.
