4. Setting the ignition positions
The system continues the startup sequence and stops in phase 36 IgnitPos. Now, the
ignition positions can be set on menu SpecialPositions.
Then, set ProgramStop to 72 PostPPos, if operation shall immediately follow.
To readjust the ignition positions after the burner has ignited: Set ProgramStop to 44
Interv 1 or 52 Interv 2 for pilot ignition after the pilot flame has been shut down. Then,
set ProgramStop to 72 PostPPos.
5. Curve settings via manual control
