I just installed a new digital thermostat. I set the temp. to 72 degrees. It has been running all night and my thermostat says it's 65. I put my hand over the vent and cool air is blowing out. Could I have gotten the wires mixed up when installing the new thermostat. Everything was fine until I installed this. I know it's not one of the timed program settings because I turned those off.
I hear the furnace blower turn on and of when i switch from heat to off. The ac kicks on when i switch to cool and the fan on the ac unit kicks on when i turn fan to on.
Thanks for any help.
