The readout on the main switch panel above the coach cooktop always says Lo scrolling across the little Aqua Hot round screen. It has never been any different since I got the coach and I have had heat most of the time. I have intermittent problems with the amount of heat, usually only luke warm air coming out of the vents. Luke warm hot water sometimes also.Could that be caused by a thermostat somewhere in the Aqua Hot that is not reading correctly and giving this lo temp reading? Any idea what to check to see if I can repair it and what it might be?
