I attempted to remove the batteries for the Aprilaire 8366 Prog Thermostat, and while it provided power, nothing could be controlled. When the new batteries were removed again and put back in, there does not seem to be any power, and there is no display. Owner's manual provides no help. Did we blow a fuse?
