“Low Voltage Reset” Feature:
Whenever the Aqua-Hot’s DC power is interrupted, the “low
voltage reset” red indicator light on the electronic controller will
illuminate. Reset the electronic controller by pressing the “low
voltage reset” button on the electronic controller (use a thin,
straight, nonmetallic object to access the button through the
faceplate) or by turning OFF the diesel-burner switch on the
interior switch panel for approximately 30 seconds, then turning
the switch back ON.
