Appliance Over
Temperature
Sensor Trip
The bimetallic snap disk mounted on the exhaust collector box has
tripped. The possible causes for this could include:
• Possibly fascia panels installed incorrectly resulting in restricted air
ow.
• Room air fans may be slowed or stalled. Check that fans are plugged
in, cleaned, and free turning
• The regulator being set too high resulting in excess heat build-up.
• The inlet ue not being connected and the appliance drawing warm
air from the cavity. Check ues are securely connected at both ends.
• Incorrect Jetting
Valve Solenoid
Check Failure
The valve solenoids have failed the pre-ignition test. This is to detect a
faulty valve solenoid. However, it is possible a wire has dislodged.
• Check that the connections to each solenoid are secure and in place.
It may be that the connections on the ends of the wires need to be
tightened a little (e.g. with a pair of pliers) to ensure a robust con-
nection to the valve terminal.
• Disconnect and reconnect the rebox connectors ensuring they are
rmly pushed into place.
• It could also be that one of the solenoids on the valve inside the re
has failed. If this is the case the valve will need to be replaced.
Remote Cannot
communicate
with re
The remote cannot communicate with the re. Reasons for this could
include:
• The re being turned o “at the wall” i.e. a loss of power to the re or
the remote is outside of its eective radio frequency range (too far
away from the re). Typical remote range is 1m to 10m.
• Ensure there is power to the re by pressing the auxiliary on/o (red)
button on the re, then press the on/o button on the remote to
clear the error.
Duct Air Over-
temp
The hot air duct temperature sensor has detected excessive heat at the
duct outlet.
• Ensure that there are at least TWO air vents installed and open in the
same room as the replace
• Ensure the duct fan is operating when the replace is running. If not
check that the duct fan cord is plugged into the replace.
Combustion Air
Flow Error
• Check whether the pressure switch is activating at startup (there is
an orange indicator LED in the control tray). If not check the pressure
switch electrical connection is correct.
• Check that the hoses are connected at both ends. Ensure the hoses
are not kinked.
• Ensure the pressure switch is mounted vertically and the diaphragm
is operational. The grey hose should be connected to the low pres-
sure port and the translucent to the high pressure port
• Check that both ues are securely connected at both ends to the
appliance and the powerue wall terminal and that the ue is not
damaged
