It was just installed, so its still being carefully monitored. So, I come home and it reports indoor temperature as 69F. I have a reference thermometer that is known accurate within 0.5F and it was reading 66.7F.
I turn the thermostat on and turn it up to 68F and heat comes on, yet its reporting 69F currently. WTF? :furious:
Once its in on mode and let it run for a while, the reference thermometer and displayed temperature agrees within 1.5F. When it is in run mode, the display temperature is never different from set temperature, so I think it is filtered to show you what they want you to see to give you the impression that its holding the temperature as you set exactly.
Internally I have no clue what its doing. How is it that actual temperature is 66.7F, report 69F and turn on the heat when its turned up from 64 to 68?
It will often change in reading by two diegrees to. I've seen it jump straight to 68 from 70, with no transition and room temperature was not rising or falling rapidly.
