22.2.1.8 Basic unit LMV52.4, Software from V04.80 to V10.00

1. New function: Temperature-compensated flue gas recirculation (FGR).
2. Driving to the low-fire positions from phase 50 is adjustable.
3. Extended monitoring of air pressure switch: New mode deactInStby.
When using this setting, the signal of the air pressure switch in standby is not
valued. In case of continuous purging, only start prevention is triggered and a
message appears, in place of a response in the form of shutdown.
4. Extended monitoring of air pressure switch for flue gas recirculation (FGR):
- New mode deactInStby.
When using this setting, the signal of the air pressure switch for flue gas
recirculation (FGR) in standby is not valued. In case of continuous purging, only
start prevention is triggered and a message appears, in place of a response in the
form of shutdown.
- New mode PS VSD.
When using this setting, the pressure switch for flue gas recirculation (FGR) must
deliver an ON signal, if the VSD speed lies above the speed set via parameter
RotSpeed PS on.
If the VSD speed lies below the speed set via parameter RotSpeed PS off, the
pressure switch for flue gas recirculation (FGR) must deliver an OFF signal.
