    how do I cancel all programming ?
    ByOct 22, 2020
    1 Answer | 
    Answer This Question

    You cannot cancel all programming, but you can change it. If you want to operate this thermostat like a non-programmable thermostat, just press hold and you can now manually raise or lower temperature, switch between Off, Heat and Cool and switch fan operation between "On" and "Auto".

    No, the temperature setpoint range is 45 to 90 degrees F. If your home is over 100 degrees the maximum setpoint for cooling is 90 degrees F.

    Answer This Question

    If I don't have a 3rd grader in the house when the time needs to be changed I'd read the instructions that come packed with the thermostat.

    Just press the Time button once, then use the up/down buttons to change the hour. Press the time button again (once) and use the up/down buttons to set the minute. when the time is correct just press the Run button once.

      I love this thermostat. I previously had the same Phillips Rogers (now Emerson) model. It was removed (without my knowledge or consultation) by workers during a remodel. The color had turned somewhat yellow with age but it still worked perfectly and I had been in the house 16 years. They installed a non-programable model from another company which I was very unhappy with. I ordered this thermostat & they graciously & promptly replaced it for me. As stated, I love it. So easy to program and just what I wanted. Highly recommend it.

      I previously had installed several years ago the White Rodgers non-programmable thermostat and it was time to replace it. I went with the programmable thermostat to help save on A/C costs in particular. The Emerson programmable thermostat is quite affordable and was easy to install with few tools necessary. The programming was better understood after watching a YouTube video showing how to install this thermostat. The written directions that come with the thermostat seemed incomplete. I installed about a week ago before the outside tempts hit high again. It has been working well. When tempts hit high 90's it was -1 degree just as the manual mentions. Very happy with this product.

      Very ease to program, the display clear and ease to read. BUT: the battery cell to big, I have to use tape to keep 2 AAA stay. The other problem is terminal label too small to read and to insert the wire is true challenge. this is why I give 3 stars
