TROUBLESHOOTING
WARNING: Turn off heater and let cool before servicing. Only a
qualified service person should service and repair heater.
CAUTION: Never use a wire, needle or similar object to clean
ODS/pilot. This can damage ODS/pilot unit.
Note: All troubleshooting items are listed in order of operation.
POSSIBLE CAUSE
1. Missing or weak batteries at
power supply box or remote. Con-
trol module may beep 10 times or
may not beep at all. LCD display
may show "BATTERY ERROR".
2. Unplugged power supply (battery)
box
3. Touch pad not plugged in to mod-
ule or plugged in incorrectly
4. Control valve wiring harness not
plugged in or not in proper position
5. Remote not communicating with
control module
REMEDY
1. Check batteries and replace if
needed. (Batteries in the power
supply box can be tested with a
multimeter at the two connections
at the back of the battery housing
where the red and black wires are
connected. Set the multimeter to
DC voltage, initiate the ignition
sequence, and observe the volt
-
age while the system is lighting
(under load). The system will not
function under 3.8 volts and bat-
teries should be replaced if the
voltage is under 4.0 volts.)
2. Plug power supply box to module
see page 16.
3. Plug touch pad in module see
page 16, figure 19. Check to see
it is positioned as shown.
4. Check to see that the control valve
wiring harness' blue connector is
plugged in to the module. Check
to see that it is aligned with the
mating pins. If any pins are visible,
then the connector is not in the
correct position. If this is the case,
disconnect, align, and reconnect
to the module.
5. Check the display on the remote
for signal bars. If the display is
blank, press any button one time
to activate the display. Watch
the display for 30 seconds and
observe if the signal bars are
shown. (The remote communi-
cates with the module periodically.
It doesn't communicate with the
module continuously to conserve
battery power.) If the remote is
communicating with the module,
signal bars will be displayed tem-
porarily. If they are not displayed
any, verify the batteries are new
and installed correctly. If the signal
bars still do not display, follow the
Re-Pairing instructions on page
17.
OBSERVED PROBLEM
Either the remote or touch pad but-
tons are pressed to start the burner
ignition sequence and there is no
function or response.
