Troubleshooting Guide
Over-Temperature
An over-temperature fault occurs only if any particular
power channel within the Reporter has reached an over-
current condition. The fault will be accompanied by the com-
ponent which triggered the fault.
Low Voltage
The Reporter is designed to operate between 11V DC
and 16V DC. A low-voltage fault will occur if the Reporter drops
below 11.8V DC. If the Reporter falls below 11.2V DC for at
least thirty seconds, it will discontinue the operation of the
Aqua-Hot as a safety mechanism.
Low-Level Cutoff
If the Reporter senses a low fluid level, the heating
system will shut down all fans, pumps, and heat sources until
the unit is refilled.
Ignition Failure
The ignition failure fault is triggered if, for some rea-
son, the burner fails to operate.
Test Functionality
The Reporter has been designed to include a host of
test features allowing for quicker diagnosis and repair of com-
ponents. Using the “PREVIOUS” and “NEXT” buttons on the
test screen as shown below, it is possible to cycle between the
burner and electrical subsystems, zone fans, and pumps.
These tests are sorted into different sections,
“TESTING - HEAT,” “TESTING– PUMPS,” “TESTING - FANS.” Only
one section of tests may be used at any one time, because of
this it is not possible to test pumps, and fans concurrently.
The Reporter will time out after five minutes and re-
turn to the home screen, and any tests which are underway at
that time will be ended.
Pumps and Zone Fans
Pumps and Zone fans are activated individually, and
remain active until the Reporter times out, or the test is manu-
ally ended. It is possible to activate multiple pumps, and multi-
ple fans concurrently for testing. However, it is not possible to
activate pumps and fans at the same time.
Heating Sub-Systems
The Reporter will allow the electric and burner sub-
systems to be independently activated and operated for a
maximum of five minutes.
Heartbeat Function
Aqua-Hot Reporter units with firmware version 5 and
later are equipped with a “heartbeat” function that is used as
a safety mechanism in the event of power loss.
The heartbeat functions by establishing a signal be-
tween the RVC system of the coach (if applicable,) and the
Reporter. The Reporter is constantly awaiting a “stay - alive”
signal from the RVC network indicating that the Reporter
should continue Aqua-Hot operation as normal. The Reporter
will cease all Aqua-Hot functionality after the loss of 6 consec-
utive signals from the RVC network. If such a situation were to
occur, the Reporter would then display “BATTERY DISCON-
NECT SWITCH OFF” in the fault log.
Tempering Valve
The tempering valve functions as a means for mixing
the hot, and cold domestic water to reduce the risk of scald-
ing. This valve is located in the middle section of the cabinet.

MIS-USE OF THIS TESTING FUNCTIONALITY COULD RESULT
IN DAMAGE TO THE AQUA-HOT UNIT. DO NOT ATTEMPT TO
SUSTAIN LONG-TERM OPERATION OF THE AQUA-HOT WITH
THE HEATING SUB-SYSTEM TEST FUNCTIONALITY.
