Title: Good programmable thermostat, great price
Review: This thermostat is easy to install, program, and operate. It's also super easy to take it off of the programming--without erasing your programming-- to leave it at a constant temperature if you go away for a few days, which is fantastic.My only minor complain (the reason for 4 stars instead of 5) is that the display doesn't light up when you press the Temperature Up and Down buttons, so you have to turn on the light in the room to see what you are doing.
