Selected coupling pattern for compressors
Sequential: Compressors are cut in/out in strict accordance
with compressor number
Cyclic: Runtime equalisation between compressors
Best fit: Compressors are cut in/out in order to
make the best possible fit to actual load
0: Sequential
2: Cyclic
3: Best fit
Main switch:
0: MAN (The compressor capacity will be controlled manually)
1: OFF (The capacity control will be stopped)
2: AUTO (The capacity is controlled by the PI controller)
Manual setting of compressor capacity
The value is in % of total capacity controlled by the controller
Displacement of suction pressure as a function of external signals
0: Reference = set reference + night offset + offset from external 0-10 V signal
1: Reference = set reference + offset from P0 optimization + night offset
