I purchased a new Bryant heating / AC system about 3 years ago. The system came with the Bryant Evolution controller. I recently noticed that in the AM when I woke up that although the period of day should have read "wake", that it was reading "evening" and that the heat had stayed up at the evening level all night (the room was heated to the level called for in the evening). Any suggestions on what might be causing this problem and how to resolve? Do I need to replace the (expensive) controller? Thanks!
