Bay Thermostat for Aqua-Hot

(1/5) > >>

LarryNCarolynShirk:
In cool weather, my bays are maintained at about 75 degrees F.  In hot weather on the road, the bays exceed 100 degrees.  I suspect the Aqua-Hot bay thermostat may be set too high or be malfunctioning altogether.  Where is the thermostat located in the bay?

Larry

Gerald Farris:
The thermostat for the bay heater on my 2000 Marquis is clipped to a water line above the holding tanks. You can see it after you remove the inspection panel at the end of the holding tanks on the passenger's side of the coach.

LarryNCarolynShirk:
Thank you Gerald, I will look for it there.  Was yours adjustable or set to a specific temperature?

Larry

Gerald Farris:
Mine is not adjustable, but I have talked to a 2001 Marquis owner who said that his basement thermostat was adjustable.

Bruce Benson:
The heat in the bays is probably a combination of many factors but I suspect the big cause is the inverter.  The second would be the heat through the wall from the Aqua hot unit.  I no longer have a basement air but that could add some heat as well I would think.  The numbers you are seeing would not be far from what I see on my coach.  

The bay heater is on top of the waste water holding tanks and is fairly isolated from the main bay.  I have no idea where the temp sensor that you see on the read out is located but I suspect it is on the rear wall area of the main bay.  Try disabling the heater and see what you get.  I suspect there will be no change.  

Someone talked about a list of screw-ups in the construction of our coaches and the location and lack of venting to the inverter would have to rank in there pretty high on my coach.
