I have this thermostat installed in a few rooms in my house and have no clue how to use it. They were put in by the builder and no manuals were left behind. I have been unable to find it on the internet at all. When I turn the temperature up and down it always reverts back to room temperature. I’ve played around with the buttons a good bit but am unable to get the thermostat to set on a temperature. Would greatly appreciate if somebody could help me out.
