It took more time to remove the old thermostat than it did to install this new one. I did read the instructions carefully, but I did not look all the way through the packaging materials. I made my own wire labels from masking tape and carefully noted what each wire was connected to on the old thermostat. As I was getting the new thermostat out to install it, out pops a complete set of stick-on wire labels! Using those would have saved a few minutes.The only thing that was not real clear was just when to attach the new thermostat to its wall-mounted base. Since I am using the optional battery backup mode, I found that I could sit in my recliner and program the thermostat, then click it into place on the wall mount. I don't use a lot of alternate programs ... just the same one each day. The "copy" option worked great. Just set up your first day, and copy it to the other days. Simple.
I have a heat pump with a second stage (very expensive to run) electric heat strip. My old thermostat would kick in that second stage whenever I clicked up the temperature setting a bit. This new thermostat lets you set just how far apart the setting for the heat pump and the second stage should be. Also, it has an "early recovery" mode that anticipates the morning "warmup" phase ahead of time, and it starts the phase early and gradually ... once again so that the second stage heat does not kick in unless it is really cold outside.
If there are any negatives, the backlight is not very bright. When you press any button you can see the display in the dark, but it isn't near as bright as a computer monitor or flat-screen tv. Still, if you are going to use this with the batteries as the sole source of power, this level of brightness would probably use minimal battery resources. If your wiring allows powering it directly from the furnace / heat pump, then it is too bad that there is not a brighter setting for the display.
