Is the "Ultimate" t-stat that A/S installed with my system the same as the Honeywell VisionPro 800 series. It sure looks the same.
Also, I have a two stage gas furnace as backup to a heat pump. When the backup (Aux) heat is engaged, does it automatically run in first stage at 65% for whatever time it supposed to run, or does it automatically kick into 100% BTU's? Also, would there be any benefit to having the first stage gas (65%) run a little longer before second stage kicked in. If so, is there a way to tell the A/S furnace to do this? Any help would be appreciated.
