Hello all, I'm new here - looks like a great forum, so I hope you'll entertain my question.
I previously owned a late-80's split level with a heat pump. The air handler was a York and the actual heat pump was a Tappan. About a year after moving in, I installed a top of the line Honeywell programmable thermostat that was advertised to be compatible with heat pumps and "hybrid" systems (heat pumps w/ conventional systems as backup). Although it cost me about $100, it seemed well worth it. After installing it myself, I had a local HVAC company inspect it and the technician indicated that it was a very good unit and much better than some of the cheaper alternatives out there. The thermostat worked wonderfully and did not require any batteries. I was extremely pleased with it the entire time I owned the house.
So, when I purchased a new home, my first instinct was to look at a Honeywell thermostat to control the conventional, Carrier natural gas furnace / central AC system (the home was built in '99 and the system is original to the house). My only problem it seems is that Honeywell has revamped their entire line since I was last in the market for one of these things. I would like a 7-day unit and preferrably one that doesn't require batteries. I was looking at the Honeywell RTH7500D, but that doesn't appear to meet my battery requirement. I may also eventually have the system converted over to a "hybrid" system in the future, so I'd like something that can handle a dual-stage setup.
I'm hoping one of you has had a similiar experience and might be able to make a recommendation. I'm open to any brand, including something that is exclusively professionally installed. Also, I should probably mention that the existing Carrier thermostat is electronic, but not programmable - not sure if that makes any difference.
