Do you just want to set it for a temp, or is it programmable?
It is not programmable, you have to push buttons to set temp for hot cold, they call it up or down.
I have tried that and it will not budge. I gather you know you are talking to a lady who does not know much about this, but common sense told me to try that. I thank you for your help.
Anything to help, I am 71 yrs.Young, but to keep getting up and down to the turn of the cool is maddening.
Ok, get a hair dryer.
Set unit for heat and turn it up just 1 or 2 degrees above room temp. Let furnace kick on, and then start warming the area around the thermostat with the hair dryer. The furnace should shut off quickly. Then before the stat can cool...turn the system to cool and dial it to 1 degree below the room temp. The ac should kick on, the stat cool one degree and then kick off. Try that as a little project when you have the time. I wish you luck.
I do not have a dial. When you show cool a number is there mune is 45 which is too cool. I keep hitting down to set the temp, but nothing happens. I will try tour suggestion.
