We have had our so program it for us. BUt, it does not make any difference it does strange things. Last night I started getting cold it felt like the air conditioner was on. When I complained about it my husband got up to check it and sure enough the AC was on. THis morning I got up so cold and my little dog was shaking with cold. It was 60 in here. At least once a week I have to call my son so he will come over and work witih it untill he can get my house warm. I realize Term. has to be programed and of course so does my son, but programing once should be enough. I acts like there is something wrong where the programer will no t take programing. I am eight to hot or freezing. Please help.
