Testing Functionality
reset or power cycled. The fault log cannot be cleared and
can contain up to four historic fault conditions not neces-
sarily related to a present issue.
Fault Conditions
The Reporter will display the following fault conditions ac-
companied by the component which caused the fault
(pump, fan, burner, etc.)
Over-Current
An Over-Current fault condition occurs when too much cur-
rent is drawn by a component, usually a fan, or pump
(output channel.) When this fault is triggered, the output
channel is shut off until the Reporter has been reset or pow-
er cycled.
Over-Temperature
An over-temperature fault will occur only if your Aqua-Hot
heating system has reached 210°F, triggering an over-
temperature condition. The Reporter will deactivate the
heater and display an over-temperature fault on the
Reporter screen
Low Voltage
The Reporter is designed to operate between 11V Direct
Current (DC), and 16V DC current. If the Reporter detects
that it is receiving voltage below 11.8V DC, a System Volt-
age fault will trigger, and display on the screen. If the Re-
porter system drops below 11.2V DC for thirty (30) seconds,
it will discontinue operation of your Aqua-Hot heating sys-
tem.
Low Level Cut Off
If the system senses low fluid level, the heating system will
shut down all fans, heat sources, and pumps until the unit is
refilled.
Ignition Failure
An ignition failure fault occurs if for some reason the burner
fails to ignite.
Test Functionality
The Reporter has been designed to include a host of test
features allowing for quicker diagnosis and repair of compo-
nents. Using the "PREVIOUS" and "NEXT" buttons on the
test screen, it is possible to cycle between it is possible to
activate burner and electrical subsystems, zone fans, and
pumps. The tests are sorted into different screens; TEST-
ING—PUMPS, TESTING—HEAT, TESTING—FANS. Only one
screen of tests may be used at any one time. Starting a
pump test, then switching to the TESTING—FANS screen will
deactivate the pump test. In addition, the Reporter will "time
-out" after five minutes of non-interaction, returning to the
home screen. This will disengage any tests currently in pro-
gress.
Pumps and Zone Fans
Pumps and zone fans are activated individually, and remain
so until the Reporter times out, or the test is manually end-
ed.
Heating Sub-systems
The Reporter will allow the electric and burner sub-systems
to be activated and run for a maximum of five minutes to
verify functionality of those systems. Please note that if
used improperly, this testing tool could cause damage to
your Aqua-Hot unit. If you have any questions, please don't
hesitate to contact the Aqua-Hot technical support depart-
ment at 1-800-685-4298.
Tempering Valve
The Tempering Valve for the Aqua-Hot mixes the heated
domestic water from the boiler tank with cold domestic wa-
ter at the present ratio to reduce the risk of scalding. This
valve is located in the back of the Aqua-Hot unit. Reference
page 7 (part #15).
To locate the Tempering Valve, remove the access cover
page 7 (part #2) and then the thermostat access cover lo-
cated above the burner. Reference page 7 (part # 15). The
pink paint witness mark verifies that the Aqua-Hot is set at
the correct factory setting and did not get tampered with
during shipping or installation.
Verify that the Tempering Valve is set at the proper tem-
perature by using a digital thermometer at one of the hot
water faucets. The water temperature should range be-
tween 115°F to 123°F. If the correct temperature cannot be
set, please contact Aqua-Hot Heating Systems Technical
Support Department at 1-800-685-4298 for additional as-
sistance or visit the web site at www.aquahot.com.
