MULTIFUNCTION REMOTE OPERATING INSTRUCTIONS
Lockout State Definition
A lockout state is reached when an ignition error occurs. The
lockout state will remain set in memory as long as the power
supplies are applied.
This could mean both an irregular flame detection and/or too many
unsuccessful ignition attempts.
This state is a safe condition for the appliance and is entered
automatically by the IFC board.
When the IFC board gets into lockout state:
1. both the Pilot and the Main Burner solenoids in the gas valve
are de-energized;
2. a diagnostic code is sent through the diagnostic red LED.
3. the IFC board will ignore any burner ignition command and
remain in the OFF state unless the unlock command sequence
is met.
The causes of lockout must be investigated under safe conditions
by the user and/or the service personnel.
To reset the IFC from a lockout state, perform the following procedure:
Turning the system power supplies (to the wall control
or remote control) OFF for two or three seconds and then
restoring a power supply back on.
The return of the system to normal operation must be checked
under safe conditions by the user and/or service personnel.
