signal"
W
Dimensioning mean temperature di erential between Sc3 air and Pc
condensing temperature at maximum load (compressor capacity = 100%).
Dimensioning temp di erence at max load, typically 8-15 K).
W

sing temperature at no load (Compressor capacity = 0%)
R
Suction pressure in °C. (Measured with the Po pressure transmitter)
W
"Select coupling pattern for compressors
0: Sequential: Compressors are cut in/out in strict ac¬cordance with com-
pressor number (FILO)
2: Cyclic: Runtime equalisation between compressors (FIFO)
3: Best t: Compressors are cut in/out in order to make the best possible t
to actual load"
