Just installed a honeywell wifi rth 8580 wf. It went smoothly connected to the internet and started running immediately. I noticed all day the indoor temperature was increasing. It was set on 75 for the last 5 hours but its 82 degrees in the house.. The setting is on auto and has been running constantly
Hello, welcome to JustAnswer. !!There is a very good chance that the thermostat is working perfectly but that the air conditioning system itself is not. We can check that out.First tell me how the system cooled the house before you fit then new thermostat.Next, tell me if the outside unit runs all of the time, or is cycling on and off.Next tell me if the fattest copper tube attached to the outside unit is running cool when the outside unit is running or not.We can go from there.
Yes, we can go to the second optionLet me know how it goesIf C contacts R directly at any point it will blow the transformer fuse. if there is no fuse it will burn out the transformer. be careful about that C must only go directly to the other 24v terminal from red, so that 24v reads between them,
Be careful about that
Good idea, this can be tricky business
