3.1 Zone Thermostat(s) Operation
Interior Room Thermostats
Simply adjust each Interior Room Thermostat to the desired temperature.
Then, whenever an Interior Room Thermostat
“calls-for-heat,”
the Aqua-
Hot’s Circulation Pump(s) and Interior Heat Exchanger 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 location of the Interior Room Thermostat(s).
Fresh Water Tank Thermostat
Simply adjust the Thermostat (i.e., Bay Heating) to approximately 40
degrees Fahrenheit. This will prevent freezing of the domestic water
storage system. Please contact your specific motorhome manufacturer
for the exact location of the Fresh Water Tank Thermostat.
SECTION 3: OPERATING INSTRUCTIONS
3.2 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
Domestic Hot Water Heating System. Please note that the
Diesel
switch must be
ON
to get an unlimited supply of hot water (i.e., during
showers).
3.3 Using the Engine Preheat System
When the Aqua-Hot is at operating temperature and the
Diesel-Burner
and/or the
Electric Heating Element(s)
switch(s) is
ON
, follow these
simple instructions:
A.
Turn the Aqua-Hot's
Engine Preheat
switch
ON
; reference
Figure 3
.
This procedure will activate the Engine Preheat Circulation Pump and
circulate the engine's coolant through the Engine Preheat System.
This feature will adequately warm the engine for easy start-ups on
cool mornings.
NOTE:
Allow approximately 1 to 2 hours of engine preheating run
time. Preheat duration will be shortest when the
Diesel
switch is
ON
.
