Interior Switch Panel - Aqua-Hot 200 Series Service Manual

Interior Switch Panel

Introduction:
The interior switch panel is used to control the two potential
heating sources for the Aqua-Hot's boiler tank. When a switch is
activated, the indicator light on the switch will illuminate.
Burner Switch:
When the burner switch is in the ON position, the control
thermostat will communicate with the relay control board and
the burner controller that heat is needed for the tank. The
burner will activate and the unit will begin to warm up.
A cold boiler tank can be expected to reach temperature
in approximately 10-20 minutes, depending on the ambient
temperature. In colder temperatures, it may take longer to heat
the unit to its operating temperature.
In order to reach and maintain temperature under all
demands, the burner switch must be in the ON position. Keep
in mind that the electric element is a
source. This means that the element can provide hot water
for simple tasks such as hand-washing, and maintaining tank
temperature at times when there is no load. The burner is
intended as the primary heat source.
Additionally, the burner switch can be used to reset a low-
voltage condition. This is accomplished by turning the switch
OFF for 30 seconds, and then turning it back on. This is known
as "power-cycling".

Electric Element Switch:
When the coach is plugged into an AC power source (i.e.
shore power or a generator) and the electric element switch is
ON, the electric heating element will be used to provide heat to
the boiler tank if the need arises. A cold boiler tank can expect
to be brought to operating temperature by the electric heating
element in 1-2 hours depending on the ambient temperature.
The electric element is intended as a
heating source. If used alone, the electric element will NOT be
able to provide enough heat for continuous hot water or interior
heat.
