The heat Source is selected from the interior switch panel. The 3-Position Switch Panel Assembly controls Burner, Electric, and Engine Preheat switches for Aqua-Hot & Hydro-Hot systems. For switch locations, consult your motor home dealer. Newer units may feature a Reporter touch-screen display instead of the interior switch panel. Confirm with your dealer or manufacturer the location and functionality of your interior control screen.

The interior switch panel is used to control the two potential heating sources for the Aqua-Hot’s boiler tank, as well as to control the engine preheat feature. When a switch is activated, the indicator light on the switch will illuminate.
