Operating the LCD & Aqua-Hot
This section will outline the basic operating instructions for the Aqua-Hot LCD Screen.
Climate Pages:
The climate pages are for all intents and purposes the
"Home" of the LCD screen. From here, the end-user will select
their interior temperature set-points, activate or deactivate the
gas burner and/or the electric element.

Zone Control (1):
Precise zone control display will differ depending on the type
of zone thermostats/thermistors used within the RV.
Section 1A demonstrates the appearance of the zone
control section when ON/OFF thermostats are used within the
RV. In this use-case, these buttons serve only as ON/OFF toggle
switches.

Tapping on one of the zones shown above will display a new
screen where the interior temperature can be set.
Section A:
This section shows the current zone
temperature (shown as 71°F in the example
above) as well as a button to turn the zone
on or off. (Setting specific temperatures can
only be done if thermistors are installed.
Thermostats would only show ON/OFF.)

Mounting the Aqua-Hot LCD Operating the LCD
If the zone temperature is set, but this item
is not set to ON, the zone heat exchanger will
not activate.
Section B:
These arrows are used to increase or decrease
the desired set-point temperature of the zone
thermistor.
Section C:
After the desired temperature set-point has
been selected tap "SET" on the LCD to set
that temperature. The Aqua-Hot will now work
to maintain this interior temperature, and the
screen will return home.
External Gas Burner Activation (2):
The external gas burner of the Aqua-Hot can be activated by
tapping on the "burner" item on-screen. The gas burner has two
modes: ON and OFF.
ON:
While set to ON, the Aqua-Hot gas burner will
work to maintain a tank temperature of 180°
F, with a minimum tank temperature of 160° F.
OFF:
While off, the gas burner will not serve to
provide any heat to the boiler of the Aqua-Hot
whatsoever.
Electrical Element Activation (3):
Similar to the external gas burner, tapping this button
will signal to the controller to activate the AC electric relay,
energizing the 1500W electric element within the Aqua-Hot.
The electric heating element has two modes: ON and OFF.
ON:
While set to ON, the electric element will work
to maintain a tank temperature of 180° F,
with a minimum tank temperature of 160° F.
OFF:
While off, the element will not serve to
provide any heat to the boiler of the Aqua-Hot
whatsoever.
