OBSERVED PROBLEM
POSSIBLE CAUSE
REMEDY
Either the remote or touch pad buttons
are pressed to start the burner ignition
sequence and there is no function or
response.
1. Missing or weak batteries at power
supply box or remote. Control mod-
ule 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 module
or plugged in incorrectly
4. Control valve wiring harness not
plugged in or not in proper position
5. Remote not communicating with
control module
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 voltage while the system is light-
ing (under load). The system will not
function under 3.8 volts and batteries
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 posi-
tion. If this is the case, disconnect,
align, and reconnect to the module.
5. The remote communicates with the
module periodically. It doesn't com-
municate with the module continu-
ously to conserve battery power.
