When the fan starts blowing air, does Flair determine it is in heat or cool mode based on what the thermostat is telling it, or does it determine the situation using duct temperature?
If I set it in 'dumb' mode ("other" not connected thermostat), it has to be the duct temperature, so if I set it to 'dumb', does it use the Flair manual set point (74 for example) to determine whether the system is heating or cooling?? Or does it wait for a reading in the 80's to think it's "heating", and 60's to think it's "cooling"?? The optimal situation would be if it compared the room temperature and duct temperature to determine if heating or cooling would result, then look at the set point vs. room temerature to determine what to do.
The reason I am asking is, if the system in 'dumb' mode uses the Flair set point to determine heating or cooling, then it should open my basement vents when the basement is cold (68), the upstairs is warm (74), and I run fan only... The duct temperature (low 70's??) would be higher than the basement room temperature (68), so it should open the vents.
I just don't know what the threshold is to determine which mode Flair thinks the HVAC is doing in dumb mode.
