UPDATE - While on the road to a new campground my aqua hot stopped working and started buzzing all the time. Had a RV mobile Aqua Hot service technician come out. Turns out the control relay box went bad. Put a new one on and it turns out this thing operates totally different. Evwr since I bought it and turned on Aqua Hot the burner and pumps ran all the time. Now it actually cycles like it is suppose to.
