    How do I change the battery? In the display window it says "low battery." What should I do?
    Community Answer
    Remove the cover carefully, more than likely it snaps on at the bottom and hangs and pivots from two little fingers at the top, pull out on the snaps at the bottom and it should lift off at the top. Now you can see the batteries to tell what type they are. Replace them and mark the date down somewhere, they will need to be replaced in about a year.

    How do I reset a lux thermostat?
    Community Answer
    To unlock the thermostat without the lock code, press the RESET button. After pressing RESET then within the next 4 seconds press the UP button 3 times then the DOWN button once. This will reset the lock code to 0000. Replace thermostat batteries with fresh AA size Duracell® or Energizer® alkaline batteries.

    On the side, there should be a green button with an arrow facing upwards and a red arrow facing downwards. The green is to get hot, and the red is to get cold.
