R/W Description / Parameter
W Width of neutral zone for compressor control
W Calibration of Po sensor
W "Main switch for start/stop of control
ON: Normal control
OFF: Control is stopped"
W Displacement value for suction pressure in con¬nection with an active
night setback signal (set in Kelvin)
W Setting of required reference pressure in °C
R Actual reference temp. for compressor capacity (incl. external reference
signal, if any)
W Max. permissible suction pressure reference
W Min. permissible suction pressure reference
R Actual status of night setback
W Setting of desired condensing pressure in °C
R Reference for condenser in °C
W Min. permitted condenser pressure reference
W Max. permitted condenser pressure reference
W Calibration of Pc sensor
W "Choice of condenser pressure reference
0: Reference = Pc setpoint
1: The reference is changed as a function of Sc3 the external temperature
signal"
W Dimensioning mean temperature differential between Sc3 air and Pc
condensing temperature at maximum load (compressor capacity = 100%).
Dimensioning temp difference at max load, typically 8-15 K).
W Minimum mean temperature difference between Sc3 air and Pc condens-
ing 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 fit: Compressors are cut in/out in order to make the best possible fit
to actual load"

R Readout compressor combinations
R Read out number of fans
W "Manual setting of compressor capacity
The value is in % of total capacity controlled by the controller"
W Select whether capacity control is stopped, in manual control or controlled
via PI controller
W Set the actual pump down limit for the last compressor
W Set max compressor capacity limit for load shed input
