The reason for the two stars is that I ran across a scenario that worried me when programming the unit. I found that if I set the program and then manually adjusted the temperature, the "Heat" indicator on the display would be off, but the output relay would be On - causing heat demand - in fact heat demand that was uncontrolled. I tested this on two units and it happened on both. Pressing the "Run" button seems to kick it out of this mode, so I still use the thermostat. Rating: 2 / 5 Thermostat is OK for the price.

I am surprised to see on the back of the package that it requires 2 AA batteries. Inside the package I found that if they run out, it's no big deal. <br /> <br />I had an electrician install it, and was glad I didn't try to follow the instructions myself as it took a while (not because of the unit but because the wiring in the house wasn't obvious). I don't have AC in the house. <br /> <br />I find the unit easy to use, not confusing, the buttons make sense. I didn't want a lot of features, or weekend settings. A light would be nice--instead I have a nightlight mounted nearby. Rating: 3 / 5 I haven’t opened the package yet, so I don’t know how many stars to give.

Must have missed it in the description. They were VERY good about taking it back. So a mistake for me but I'll continue to buy from Amazon with confidence.
