Diesel Aqua Hot

<< < (5/6) > >>

Fred Brooks:
      Jerry, I am not sure why Aqua-hot sets the 12volt threshold so high. I do know that PC boards do not handle low voltage well but it does not take much to trigger the "low voltage" on hydro-hot or aqua-hot boards. I tell my customers just leave some tooth picks on the floor near the control box and reset when necessary. Fred

I have tried leaving the tooth picks in there but they must blow around or something when I'm driving.  I never find any in there.  At least it doesn't take me 3 hours to get the HH running anymore when it quits.  The first time I needed it I think it took 2 days to get hot water.

George H. Wall:
Jerry, Try taping 2 or 3 long toothpicks down with some duct tape, they will stay there!!   Henry

Fred Brooks:
     You can always wrap a tooth pick with some Velcro then install right on the face panel next to the access hole. Fred

Joel Ashley:
I agree with taping the toothpicks to the box as the option had also occurred to me, but I think Jerry shouldn't be needing them so often in the first place.  He needs to resolve why the unit is sensing low voltage so often.  In over 10 years I've used the reset button once, and the diesel switch reset probably 2 times, after discovering I didn't need to use the control box recessed button afterall.  It's not often I've allowed the battery bank to slip much.  In fact I'm still on the original factory-installed batteries.
