I have 1 Gas furnace & 1 AC system.
Thanks both. Is the VisionPro 8000 compatible with 24V system? Also, Honeywell lists various model #s for VisionPro 8000. What is significance of Model #s?
Model Numbers: TH8110U1003,...
I have 24V coming to thermostat and also have 3 batteries.
I have a new RTH8500. Can I make the backlit stay always on? If so, how?
