I haven't quite figured out my new controller. I came home last night and the a/c was running on high speed and I was at set point. My humidity level was below my set point so It was not running to drop it. What other reasons would my system be running on high for when I set the thermostat at 75 and it was actually colder than 75 in the house. THe thermostat said 75 but I measured the temp with another digital thermostat and it was cooler than 75. Does my thermostat look at other conditions like outside temp and keep running based on other info besides the set point? I was not set to schedule so it was not looking at the next temp set.
