The Aqua-Hot Reporter
The Aqua-Hot Reporter is a new generation of command and
control module that manages all functions of the Aqua-Hot from
start-up to shutdown. The Reporter is used across the 400,
450, 600, and 675 units. The previously used electronic control
board has been retired on new units in favor of the Reporter.
There are two series of Reporters presently in use: Reporter
1.0 and Reporter 2.0. Reporter 1.0 was launched November
30, 2018, and Reporter 2.0 was launched September 9, 2019.
The launch of Reporter 2.0 allowed an opportunity to improve
upon the 1.0 design where ever it was deemed necessary. The
Reporter 2.0 features the following design improvements:
• Over-Temperature Fault Functionality
• Precise fl uid coolant temperature display
• Boost pumps are now powered directly by the Reporter
• 600D/675D Owners may now select a pump for fl uid stir
Functionality:
The Reporter was designed with a touch-screen interface to
simplify and standardize unit use and troubleshooting. Screen
navigation and access is now standardized across the Aqua-Hot
400 Series Propane/Diesel (PO2/D02 and newer), 450 Series
Diesel (DE5 and newer), and 600 Series (D04 and newer).
The Reporter also contains fault logging functionality,
troubleshooting tools, and testing functions. Each of these
functions will be explained in detail.
Basic Features:
The Home Screen is the fi rst screen shown on the Reporter.
Reporter 1.0 and Reporter 2.0 home screens do differ.
The most substantial difference between the Reporter
1.0 and 2.0 is th inclusion of a thermistor in place of the
standard control thermostat. This allows specifi c Aqua-Hot
coolant tank temperatures to be displayed on the Reporter, and
relayed to the on-board comfort control systems (if the coach
manufacturer installs one). The tank temperature sensor allows
more granular control of the Aqua-Hot by switching away from
the static temperature limitations imposed by the previous
control thermostat.
The Reporter contains a host of diagnostic and troubleshooting
tools to more easily repair and operate Aqua-Hot units. These
features are organized into pages and sections that are further
explained in this guide.
Home Screen
The home screen contains information about
the Aqua-Hot system status, as well as model
and serial number information.
Fault Status
The fault status page contains the last seven
faults which were observed by the Reporter,
regardless of how much time has passed.
Coach Side I/O
This page of the Reporter will indicate the
current status of elements and switches within
the coach; such as, the coach is requesting hot
water or heat.
Aqua-Hot I/O
The Aqua-Hot I/O page will show the current
status of elements, sensors, and components
within the Aqua-Hot itself.

Heartbeat Function
Heat Testing:
The heat testing page of the Reporter will allow the electric
and burner heating sub-systems to be independently
activated for troubleshooting and testing purposes.
Fan Testing:
The fan testing section of the Reporter will allow the
heat exchanger fans within the coach to be activated
independently of the rest of the Aqua-Hot.
Pump Testing:
The pump testing page of the Reporter functions similarly to
the fan testing page in that, from this Reporter page, pumps
within the Aqua-Hot can be activated independently from
other elements for their functionality to be verifi ed.
Figure 5
Figure 6
Figure 7
Heartbeat Function
Aqua-Hot Reporter units with at least fi rmware version 1v5
and all Reporter 2.0 units are equipped with a “heartbeat”
function which establishes a signal between the RVC system
and the Reporter.
The Reporter will be constantly awaiting a signal from the
RVC network indicating to the Reporter that it is to continue
normal operation. Loss of 6 consecutive signals from the RVC
network will trigger the Reporter to de-activate the Aqua-Hot.
This serves as a safety feature to ensure that the Aqua-Hot
does not continue to operate if the coach loses power. Once
power is restored to the coach and the Reporter unit, “BATTERY
DISCONNECT SWITCH OFF” will be displayed in the fault log,
indicating that the Reporter has lost connectivity with the RVC
network, and subsequently deactivated.
Technical Information
Mounting:
The Aqua-Hot Reporter can be mounted in two different
fashions, either surface mount, or recessed mount. Dimensional
specifi cations are shown below. When surface mounting, use a
#10 or larger screw. If recessed mounting, use a #6 screw.
There is a slot located at the bottom of the Reporter which
serves as access for the harness and power connections. Take
these into consideration when choosing the mounting location
for the Reporter. Circular dimensions are edge to center.
Aqua-Hot sheet metal cabinets have reference features
indented into them for mounting the Reporter to the Aqua-Hot
if desired.

Boost Pumps
Boost Pumps
Boost pump functionality has changed with the
implementation of the Reporter 2.0.
On Reporter 1.0 units, any boost pumps at use within the
coach required a relay connected to wires 3b and 5b in order
to operate.
With Reporter 2.0, that relay can now be eliminated, with
boost pump power and functionality now being handled directly
by the Reporter. Using a fl ag-terminal, connect the boost pump
directly to the harness bearing in mind the requirements below.
• Zone 1: Connect to Wire 3b
Max Current Draw: 5.0A
Over-Current Condition: 8.0A
• Zone 2: Connect to Wire 5b
Max Current Draw: 3.0A
Over-Current Condition: 5.0A
Original Equipment Manufacturers (OEMs) will need to
provide the ground for operating boost pumps from the Reporter.
Electrical Specifi cations:
The Reporter contains a single Amphenol ATP family
connector that serves as the power connection to the coach
side 12V DC power system. Mating connection components
are not supplied by Aqua-Hot. Compatiable part numbers and
manufacturers are supplied below. The Reporter must be
operated to the below listed specifi cations.
Minimum Voltage.....................................11.0V DC
Maximum Voltage....................................15.0 V DC
Minimum Current.....................................75mA
Maximum Current....................................15A
Please note that the minimum current rating is the minimum
requirement for what will operate the Reporter. Operating
at this current rating will not provide suffi cient power to any
components dependent upon the Reporter.

Filling and Purging the Aqua-Hot
Introduction:
Filling the Aqua-Hot will be one of the last steps to be
completed after installing an Aqua-Hot. The fi ll procedure
differs from older Aqua-Hot units due to the introduction of the
Reporter.
Instructions:
1. Locate the fl uid drain port of the Aqua-Hot. This is located
at the front of the unit near the bottom of the tank face.
2. Connect an external fl uid fi ll pump to the fl uid drain valve.
A 1/2” NPT barbed fi tting is best suited for this task.
3. Place the supply line of the pump in a source of GRAS
propylene glycol antifreeze.
4. Locate the Reporter, and navigate to the “INPUTS FROM
AQUA-HOT” page.
5. Pay attention of the “LOW LEVEL SENSOR” item on this
page.
6. Fill the tank to approximately 3/4 full, or until the “LOW
LEVEL SENSOR” item displays “TANK FULL”.
7. Once the tank is partially full, deactivate the external fl uid
fi ll pump and close the drain valve. DO NOT disconnect the
fl uid pump.
8. Navigate to the “PUMPS” page of the “TESTING” section.
Figure 9
Figure 10
9. Tap each of the pumps to independently activate them,
beginning the heating loop purge procedure. These
pumps will remain active for a maximum of 5 minutes.
They will need to be reactivated as needed until the purge
procedure is complete.
10. Continue to fi ll the unit as air is purged from the interior
heating loop.
11. Once the air is no longer returned from the heating zone
return ports, deactivate the fl uid circulation pumps.
12. Open the fl uid drain valve, and activate the external
fl uid fi ll pump. Fill the unit with GRAS propylene glycol
antifreeze and water heating solution until it reaches the
“COLD” mark on the fl uid expansion bottle.
NOTE: Do not fi ll this unit completely. Filling the unit com-
pletely runs the risk of air-locking, preventing the heating
zone from correctly circulating and draining the air.

Fault Conditions
Fault Conditions
Introduction:
The Reporter contains fi ve distinct categories of fault
conditions which will assist in diagnosing and repairing the
Aqua-Hot should problems arise. Low-voltage, over-temperature,
and over-voltage fault conditions will be accompanied by the
component which triggered the fault. It is best practice to record
all conditions at the “FAULT” screen. Fault conditions are also
recorded in the fault log on the “TEST” tab. When using the fault
log, it is important to know that this log cannot be cleared, and
may contain information on faults not pertaining to a present
issue.
Reset Feature
The RESET button shown above on the Reporter fault
screen can be used to reset the Reporter after a component
has been changed or modifi ed. Some components will require
a full power-cycle in order to fully reset the Aqua-Hot system.
Over-Current
An over-current fault condition occurs when too much
current is drawn by a component (output channel), usually a fan
or pump. When an over-current condition occurs, the Reporter
will deactivate the Aqua-Hot heater as a safety measure to
prevent damage. This fault can only be cleared once the
Reporter has been reset. Please note, that if the responsible
component is not repaired or replaced, it can continually cause
over-current fault conditions, thereby impacting the functionality
of the Aqua-Hot unit.
Over-Temperature (Reporter 2.0)
The Over-Temperature fault condition occurs when the
tank temperature sensor indicates that the unit has overheated.
An overheat is realized when the antifreeze and water heating
solution within the Aqua-Hot exceeds 210°F.
Low-Voltage
The Reporter is designed to operate between 11V
Direct Current (DC) and 16V DC. If the Reporter detects that it is
receiving less than 11.8V DC, it will display a low-voltage fault. If
the Reporter drops below 11.2V DC for more than 30 seconds,
a safety mechanism will activate, shutting down the Aqua-Hot.
Low-Level Cut Off
Aqua-Hot units require a minimum amount of antifreeze
in order to function correctly. Keep in mind that the exact fl uid
volume may differ depending on the layout of your coach.
If the heater drops below the minimum fi ll level as indicated
on the expansion bottle, the Reporter will shut down all fans,
pumps, and heat sources until the unit has been refi lled and
the Reporter has been reset.
Ignition Failure
Ignition failure fault conditions will occur if the burner
inside the heater fails to ignite. This is all the fault condition
will display. Precise diagnosis herein will require in-depth
troubleshooting.
Testing
Introduction:
The Reporter retains the functionality to independently
activate certain components and sub-systems within the Aqua-
Hot heater. The systems that can be independently activated
are the burner, electric element, and burner indicator light.
For testing procedures, only one system can be activated as
independent components. These components and sub-systems
will remain active for only fi ve minutes, and are NOT a substitute
for normal operation. Aqua-Hot Heating Systems is not liable for
damages resulting from attempting to use testing functions in
place of standard operation.
Pumps
Pumps on your heater can be independently activated using
the Reporter. These can be used to verify functionality, or to
purge fl uid lines of air. Select each pump from the screen to
activate. Keep in mind that these testing screens will ignore
input from the fl uid level sensor. On Reporter units with fi rmware
version 1v7 and earlier, pump 2 will serve as the stir pump on
600 Series and Pump 3 serves as the stir pump on 400 Series.
600D and 675D units with fi rmware version 1v8 and later,
and all Reporter 2.0 units allow for stir pump selection between
zone 2 and zone 3 pumps. This setting can be accessed by
pressing and holding the serial number panel on the Home
screen.

Testing
Fans
Using the “FANS” screen, it is possible to activate fans in
each zone to test for functionality. This is similar to the pumps
screen, allowng you to activate one or multiple fans at the same
time by selecting the desired fan.
Heating
The heating tab will allow the burner, burner indicator light,
and the electric element to be activated and run for fi ve minutes
to test for functionality. During this time, inputs from the control
thermostat are ignored to allow the test to take place. Do NOT
activate the burner heat test without allowing the unit to cool.
Not doing so could complicate further diagnosis and may cause
irreparable damage to the Aqua-Hot.
Diagnostic
The “DIAG” tab of the Reporter allows the user or
technician to access input and output information to record
communication information within the Aqua-Hot heater, and
between the heater and the coach. This tab is read-only and
will not allow the manipulation of the elements listed. There
are four screens maintained under this tab: Inputs from Coach,
Outputs to Coach, Inputs from Aqua-Hot, and Outputs to Aqua-
Hot.

RVC Network Connectivity
The Reporter was designed to interface with the coach-side
RVC network to aid in the Aqua-Hot’s integration into the on-
board RVC network.
There is an indicator light on the back of the Reporter which
shows the current status of the Reporter’s connection to the
RVC network. This will be useful when diagnosing potential
problems with the coach-side RVC network.
Once the test page is open, select the MANUAL MODE and
select “NEXT”. Manual mode will continue to run for up to 3
days without any user intervention. Pressing the reset button
at any time while enabled will reset the timer, and run for an
additional 3 days.
All heating zones are linked together and can be run at
25%, 50%, 75%, and 100% (as shown below). The burner and
electric can be enabled or disabled. For all levels, there is a 10
minute duty cycle period that will allow Cozy fans to be on for
the specifi ed percentage of 10 minutes. Example, 25% would
be on for 2.5 minutes, and then off for 7.5 minutes. It always
starts with the on-cycle, then shuts off for the remainder of the
10 minute period.
If the system power is cycled, the manual mode will be disabled
and must be manually re-enabled. Leaving the manual mode
page will also disable manual mode and restore normal
operation. Leaving manual mode should be done once the
system failure has been resolved and normal operation can
resume.
Please call the Technical Service Department if you encounter
any diffi culties while performing this procedure. 1 800-685-
4298 from 7:00am-4:00pm MST Monday through Friday.
Manual Mode
The 2.0 Reporters with CFG 1.9 and greater come with a
manual mode in case the general coach RVC network fails. It
will allow for limited operation while the larger network/module
problem is addressed.
This mode can accessed under the test page of the Aqua-
Hot Reporter (see below).
NOTE: If using the rocker switches, burner & electric switches
must be toggled on/off after leaving Manual Mode.
NOTE: On the 600/675 units, electric can be operated in low
or high modes.
