Heating System Features
Switches
The Aqua-Hot Heating System is controlled by two
switches, the burner switch and the electric element switch.
This style of Aqua-Hot is equipped with an Engine Preheat ele-
ment as well. When one or both of the burner or electric ele-
ment switches are in the “ON” position, it will supply the nec-
essary heat to the boiler tank. Keep in mind that the Aqua-Hot
must be at operating temperature for the heating zones and
hot water to function properly. Please contact the specific
coach dealer for the exact location of switch locations.
The Aqua-Hot interior switch panel has a high/low
switch that will operate in conjunction with the electric ele-
ment switch.
•
Low Switch
Moving the High/Low switch to the “LOW” position will
energize one of the two AC elements inside of the
Aqua-
Hot. On the “LOW” setting, allow 1
-2 hours for
the Aqua-Hot to reach operating temperature.
•
High Switch
Moving the High/Low switch to the “HIGH” position
will energize both AC electric elements within the
Aqua-Hot, providing adequate heat for light-duty heat-
ing and hot water needs. Allow 30 minutes to 1 hour
for the Aqua-Hot to heat to operating temperature
with the “HIGH” setting activated.
Thermostats
The interior room thermostat can be set at a desired
temperature, signaling to the Aqua-
Hot that it is “calling for
heat.” Once this occurs, the Aqua
-Hot circulation pump, interi-
or heat exchangers, and heat source will be activated, thereby
providing heat to the coach.
NOTE: The fresh water thermostat controls the bay heating
area and should NOT be set below 40°F to prevent freezing
of the domestic water storage system. Please contact the
specific coach dealer for the exact location of the thermostat
controls.
