I've got my Quad Mt Vernon AE programmed to turn on every afternoon at 5PM and run till 10PM at which time it shuts down. Once in a while I'd like to run the unit a little just to take the chill off the room where it is installed and in which my wife and I are sitting. From what I can tell, the only way to do that is to erase the program and run on thermostat. Is anyone familiar with this that might be able to give me some guidance. Thank you.
