C16 Kind of compressors: to set the kind of compressors.
SPo = compressors with the same capacity.
BtZ = screw compressors like Bitzer, Hanbell, Refcomp etc operation.
Frtz = screw compressors like Frascold operation.
C17 Valve output polarity - circuit 1: valve polarity: polarity of the outputs for capacity valves. It
determines the state of the relays associated with the capacity valves:
oP=valve enabled with open contact;
cL= valve enabled with closed contact.
C18 Valve output polarity - circuit 2: valve polarity: polarity of the outputs for capacity valves. It
determines the state of the relays associated with the capacity valves:
oP=valve enabled with open contact;
cL= valve enabled with closed contact.
C34 Kind of gas: set the kind of freon used in the plant
r22 = R22; r404= R404A ; 507= R507; 134=134; r717=r717 (ammonia); co2 = CO2; 410 = r410.
Setting the kind of gas, the XC1000D can associate the pressure with the matching temperature.
C35 Activation time during the switching on of first step (valve of 25%) for Bitzer screw
compressors: (0÷255s): it sets for how long the valve is used during the startup phase.
C36 First step enabled during the regulation (switching off phase): it sets if the first step can be
used also during normal regulation.
NO = first step used only during the start phase
YES = first step used also during normal regulation
6.1.2 Regulation (C37-C44)
C37 Type of regulation for compressor circuit 1:db = neutral zone, Pb = proportional band.
C38 Type of regulation for compressor circuit 2: db = neutral zone, Pb = proportional band.
C41 Compressor rotation circuit 1:
YES = rotation: the algorithm distributes the working time between loads to ensure even run times.
no = fixed sequence: the compressors are enabled and disabled in fixed sequence: first, second etc.
C42 Compressor rotation circuit 2:
YES = rotation: the algorithm distributes the working time between loads to ensure even run times.
no = fixed sequence: the compressors are enabled and disabled in fixed sequence: first, second etc.
C43 Fan rotation circuit 1:
YES = rotation: the algorithm distributes the working time between loads to ensure even run times.
no = fixed sequence: the fans are enabled and disabled in fixed sequence: first, second etc.
C44 Fan rotation circuit 2:
YES = rotation: the algorithm distributes the working time between loads to ensure even run times.
no = fixed sequence: the fans are enabled and disabled in fixed sequence: first, second etc.
6.1.3 Display (C45-C46)
C45 Displaying measurement unit: it sets the measurement unit used for the display and for
parameters that are connected to temperature/pressure. In pharentesis other measurement unit.
CDEC: °C with decimal point (bar);
