Zone Thermostat Operation
Interior Room Thermostat:
Simply adjust each Interior Room Thermostat to the de-
sired temperature. Then, whenever an Interior Room
Thermostat “calls for heat,” the Aqua-Hot’s Circulation
Pump and Interior Heat Exchanger Fans will be acti-
vated. These devices, together, will supply warmth and
comfort to each interior heating zone. The Aqua-Hot
must be at operating temperature in order for the zones
to function. Please contact the specific motor home
manufacturer for the exact location of the Interior Room
Thermostats.
Fresh Water Tank Thermostat:
Simply adjust the Thermostat for Bay Heating to a mini-
mum of 40°F. This will prevent freezing of the domestic
water storage system. Please contact the specific motor
home manufacturer for the exact location of the Fresh
Water Tank Thermostat.
Using the Domestic Water Heating System
When the Aqua-Hot is at operating temperature, the do-
mestic 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 sup-
ply 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 Water Heat-
ing System. The Diesel-Burner switch on the Interior
Switch Panel must be
ON in order to obtain a continu-
ous supply of hot water (e.g., during showers); be sure
to also activate the Electric Element switch for
maxi-
mum
hot water capacity. Reference Figure 4.
NOTE: Both the Diesel-Burner and Electric Heating Element
are thermostatically controlled. Either or both heating
sources will automatically maintain the temperature
of the Aqua-Hot’s antifreeze and water heating solu-
tion between approximately 160
⁰
F and 190
⁰
F(±5).
Therefore, to heat the motorhome/domestic hot wa-
ter, simply choose the desired heat source(s) and
leave the switch(es) (i.e., Diesel-Burner and or Elec-
tric Element)
ON .
NOTE: The Aqua-Hot’s “Domestic Water Priority System”
disables the interior zone heating fans and the zone
circulation pumps whenever domestic hot water is
being used on a continuous basis (e.g., during show-
ers). Once the demand for continuous domestic hot
water ceases, the Aqua-Hot will enable the fans and
the pumps to operate and provide heat to the Heat-
ing Zones.
