excellent thermostat and it can be back lit
I reviewed this thermostat a couple of years ago and gave it an excellent rating. At the time I didn't think the display could be backlit as advertised, and was a little disappointed. I just consulted with an a.c. tech about something else, and he showed me how to turn on the back light to this thermostat. Maybe I didn't see it in the original instructions, or maybe it wasn't in there. And after having read the more recent reviews here, I realize others have come to the same conclusion and thought there was no backlit display. Here is how to turn it on: 1. turn the selector switch to heat 2. press the temperature up and down buttons at the same time for a few seconds until the word 'on' appears in the display. 3. Then push the up temperature control 4. Then switch the selector switch back to off. The back light should now be working whenever a temperature button is pushed. Originally, the tech told me to remove the front cover from the thermostat when doing this, but it seems to work if I just leave it together. And repeating these steps will turn the light back off. This worked for me and a friend who has the same thermostat, and hope I this can be of help to others.

I wanted a simple upgrade from mechanical to digital. Plus I needed a vertical thermostat to cover the existing plate. Works well.
