I guess I should have read the description closer. It says it is compatable with heat pumps systems so I thought I was ok. We get it installed (which wasn’t too difficult) and it doesn’t seem to be working properly. I start looking through the book and then finally go to the honeywell website to discover that it does not work with heat pump systems that also have emergency heat/back up heat, which I have. Fabulous, my poor husband is now in the process of reinstalling our old thermostat while I process the return. Item description says it is not compatable but I guess I didn’t read it very closely since I tend to focus on customer reviews. Guess we are stuck with a manual thermostat.

This thermostat is great… it allows you to program it to only heat/cool your place while you are there, which saves you money. If you are an environmentalist then you will realize that it is saving resources by only heating or cooling while you are home. An awesome product.

I purchased this item for my home and installed very quickly and easily. It works perfect and is easy to program on each day of the week. Highly recommend this if you are in the market for a programmable thermostat.

Only get this part if you have 5 wires or less for your system. I don’t remember seeing this on the item details. So ended up wasting money on this item. Had to get a RTH7600 to connect to an 8 wire heat pump system.

This thermastat works very well, was a breeze to set up and the updated look is very nice compared to the old manual thermastat.
