I have a programmable control unit, and i had bought this programmable control device because I wanted to try to save a lot of money on the electric bills that were kind of high.
They were high because our central heating and a/c was regularly going twenty 4 hours per day and 7 afternoons per week, and when I bought the programmable control device it would put an end to all of that not needed use of the central heating and a/c all the time, then however, our programmable control device was not quite right when I first bought it.
It must have been a factory defect or something. Any time you would set the temperature to a particular setting it would really heat or cool the beach house a few degrees off from what it was set at. This was something that I could not rest any longer, so what I did was made a call to the local heating and a/c company that sold me the thing. They then in turn went and sent out a single of their certified heating and a/c specialists. The certified heating and a/c specialist was able to service the factory defect in our programmable control device and I was finally having a smart control device that completely worked perfect! And also I can tell you that our central heating and a/c does not go that much like it used to. The programmable control device will make sure that our beach house remains at the exact temperature that I set the programmable control device to!
