NOTE: Both the Diesel-Burner and the 120 VAC Electric Heating Element
are thermostatically controlled. Either, or both, heating sources will
automatically maintain the temperature of the Aqua-Hot's water and
antifreeze solution between approximately 175-200 degrees Fahrenheit.
So simply choose how you want to heat your coach/hot water and just
leave the Switch(s) (Diesel, Electric, or both) ON.
2.2 Zone Thermostat(s) Operation
Interior Room Thermostats
Simply adjust each Room Thermostat to the desired temperature. Then
whenever a Room Thermostat "calls-for-heat" the Aqua-Hot's Circulation
Pump(s) and Interior Zone Fans will be activated. These devices together
will supply warmth and comfort to each interior heating zone. Please
contact your specific motorhome manufacturer for the exact Room
Thermostat location(s).
Bay Thermostat
Simply adjust the Bay Thermostat to approximately 40 degrees
Fahrenheit. This will prevent freezing of the domestic water storage
system. Please contact your specific motorhome manufacturer for the
exact Bay Thermostat location.

2.3 Using the Domestic Hot Water System
When the Aqua-Hot is at operating temperature, the domestic water is
automatically heated as it is being used. Because the Aqua-Hot does not
store any hot water simply open any hot water faucet and a continuous
supply of domestic hot water will be present within a few seconds. This hot
water feature is continuous and is accomplished by the Aqua-Hot's Mixer
Valve and Intergal Domestic Hot Water Heating System. Please note that
the Diesel-Burner Control Switch must be ON to get an unlimited supply of
hot water (i.e. during showers).
2.4 Using the Engine Preheat System
When the Aqua-Hot is at operating temperature, and the Diesel-Burner
and/or the 120 VAC Electric Heating Element Switch(s) is ON, follow
these simple instructions:
A. Turn the Aqua-Hot's Engine Preheat Switch ON. This procedure will
activate the Engine Preheat Circulation Pump. Circulating the engine's
coolant through the Engine Preheat System will adequately warm the
engine for easy start-ups on cool mornings. Please contact your specific
motorhome manufacturer for the exact Engine Preheat Switch location.
NOTE: Allow approximately 1 to 2 hours of engine preheating run time.
Time will be shortest when the Diesel-Burner Control Switch is ON.
