My HVAC guys finally have just finished up tying my hot water boiler and heat pump together so that the heatpump in heating mode runs above 40 degrees and the gas hot water below 40 degrees. This had been working correctly but the reversing valve would not switch to allow AC. So they have finished up after having to add an isolation relay. All background.
I noticed the setting value for 220 was changed from 3 to 5 (1st Stage compressor cycle rate). What does this setting do (I think it goes from 0 to 6)??? I think these are all called "comfort setting" but how do I know if this is better or worse??
