I just bought a house with this thermostat. I dont want it programmed to change temps at different times. I just want it to kick on when it get below or above a certain temp in my house. I thought I did this last night. But i came home this evening and it was 58° in my house. That is much warmer than the -22° it is outside, but not warm enough. Finally i moved the temp up to 72° and hit run. I also turned the fan to on instead of auto. 2 hours later I webt back to check and it was back to 58°! HELP!
