Thanks for the response. At first I didn't understand it because on my system the indexing switches didn't pop back up during day mode. I finally realized that the thermostats had been damaged by bad air at some point. As I have replaced them I see that in day mode they do pop right back up. This channel is a fantastic resource. Thanks again.
On the dual thermostat, if the manual override push button is depressed during the day (15 psi supply), does it have any effect? Is the push button supposed to automatically return to the up position, if so, what triggers that?
