I purchased two of these thermostats through the Amazon website and installed them just before the start of the Memorial Day weekend. I am very pleased with both thermostats, but I did encounter a problem during the install of the upstairs thermostat. Although I had flipped the breakers labeled for the upstairs and downstairs heat pumps to the off position at the panel, the upstairs heat pump was still receiving power, because I blew a fuse in the heat pump during the install. Obviously this problem was caused by a lack of due diligence on my part - ensuring that the power to the heat pump and to the thermostat was really off. My wife and I went without air conditioning to the upstairs of our home for approximately 30 hours before a service technician arrived to find and replace the blown fuse.
If you have a volt ohm meter, I suggest that you verify that there is no power to the thermostat prior to the install. In doing the install yourself, you may find that you are at...
First the negative...
The Installation Guide needs revision. I spoke to Honeywell about this and other complaints and hopefully these issues will be changed. BTW, they were very nice.
First problem: To set the system preferences is says to press the left button and then hold the middle button down for 5 seconds. It didn't work. It will work on older models, but on the newer ones they changed the operation of the unit so that pressing a button first turns on the backlight. Once the backlight is on, then press the buttons again to get the desired response. This isn't mentioned in the manual.
Second problem: Since I am retired, I don't need the "Leave" and "Return" settings. There is no way to cancel these. Of course, you can set the time for these to match the "Wake" and "Sleep" times, it just seems like added work and is not intuitive. Some of the lower priced models have the ability to cancel these settings.
