IGNITION MODULE DIAGNOSTIC INDICATOR FLASHES:
The LED will flash on for 1/4 second, then off for 1/4 second during
a fault condition. The pause between fault codes is 3 seconds.
STEADY ON - Control Fault
(1) FLASHES - Air Flow Fault
(2) FLASHES - Flame Sensed with No Call For Heat
(3) FLASHES - Ignition Lockout
STEADY ON:
Internal control failure.
AIR FLOW FAULT:
Combustion air flow is continually monitored during an ignition
sequence by the air flow switch (PSW). If during the initial call for
heat the pressure switch contacts are in the closed position for 30
seconds without an output to the combustion blower, an air flow
fault will be declared and the control will remain in this mode with
the combustion blower off.
FLAME FAULT:
If at any time the main valve fails to close completely and maintains
a flame, the full time flame sense circuit will detect it and energize
the combustion blower. Should the main valve later close completely
removing the flame signal, the combustion blower will power off
following the optional post purge period.
IGNITION LOCKOUT:
Should the main burner fail to light, or flame is not detected during
the trial for ignition period, the contol will go into lockout. The valve
will be turned off immediately, and the combustion blower will be
turned off following the optional post purge period.
