I am using the drivers from Aprilaire and all works fine. Just have a question on the two way heat and cool variable. For example when I access any of the rooms and turn on the heat, I have to tap the heat variable (the 70) in order for it to show the correct room temperature before I can hit the up or down button to change the heat. It seems to hold the last temp on the screen from the last time I was on this page? Just curious why when I enter this page, it is note updated without tapping. what is strange, the outdoor and indoor temps are always up to date?
