I had trouble finding programable thermostats that would control my split system Carrier heat pump. Honeywell has the installation manuals for every one of their units online ([...] I spent time looking at this unit's documentation to be sure it could handle my Carrier unit. Be careful, many Honeywell and other manufacturers have units that don't handle heat pumps, and some include "call a professional" in their instructions. Setup was a cinch and the ability to program temps for four times per day for up to seven days will save me money throughout the year. It's a simple unit, seems compatible with most systems, has some neat features like "vacation hold" where you can override all the programming and set a temperature to "hold" until you reset it for programming. You could be away for an evening or a month...it would honor the "hold" setting.


There are a couple of "if this...then that" instructions, but they're really well put. I did notice a poor rating on one of Honeywell's other thermostats because one purchaser didn't realize the difference between possibilities linked with "AND" vs. "OR". "And" means EACH MUST EXIST, "Or" means ONLY ONE OF THEM SHOULD EXIST. So, although the instructions are excellent, they must be read carefully before using the unit on a more complex system, such as a heat pump.

Only thing I'm not too happy about is the very short time the backlight stays on...barely five seconds. Unfortunately, in my house, the unit is mounted in an area with little natural or ambient light. I'm sure once the screen is totally familiar to me this won't matter much. But, learning the system and setting the various "System settings" takes reading along with the Installation Guide and the screen is constantly going black. Maybe I just haven't found the setting that lets it stay on longer...

I'm not experienced with HVAC. I'm a 62 year old woman/avid home "improver" and installing this in place of the 25 year old mechanical mercury stat was very easy...maybe 30 minutes.
