Honeywell Thermostat setup codes
My Honeywell Vision Pro, TH8320U1008,thermostat recently started firing up the furnace a good 3 hours before it's programmed to. The screen indicates it's "Recovering from Schedule" instead of the normal "Following Schedule" message. I think the Adaptive Intelligent Recovery function may be damaged so I'm trying to turn it off. I go into setup and the highest code I see is 290, which if I change to a value of 1 or 2, I'll see more codes, namely, code 530, which toggles the Adptive Intelligent recovery function. My problem is that I can't seem to save my change to code 290 so the higher codes show.
