Program 9 – direct frequency request with cascading
For cascading with signal overlap, the 1st outdoor unit is controlled by an external analog signal
between the following signal ranges:
Analog signal type Signal range of 1st outdoor unit
0-10 V DC 1 to 5.8 V DC
0-5 V DC 0.5 to 2.9 V DC
0-20 mA 2 to 11.6 mA
4-20 mA 5.6 to 13.3 mA
Table 59: Direct frequency request with cascading with signal overlap – signal range of 1st air conditioning unit
At and above the following analog signals, the 2nd outdoor unit also already starts up, until the
maximum compressor frequency is reached:
Analog signal type Signal of 2nd outdoor unit
0-10 V DC 5 V DC
0-5 V DC 2.5 V DC
0-20 mA 10 mA
4-20 mA 12 mA
Table 60: Direct frequency request with cascading with signal overlap – signal of 2nd air conditioning unit
The analog signals of the 1st and 2nd outdoor unit overlap between the following signal ranges:
Analog signal type Signal overlap of 1st and 2nd outdoor units
0-10 V DC 5 to 5.8 V DC
0-5 V DC 2.5 to 2.9 V DC
0-20 mA 10 to 11.6 mA
4-20 mA 12 to 13.3 mA

For a description of setting signal ranges C and D for cascading with signal overlap, see section
“15.4.1 Setting the signal ranges via DIP switch S2” on page 82.
15.4.1 Setting the signal ranges via DIP switch S2
16 signal ranges are stored in the CompTrol Interface. On both CompTrol Interface expansion
modules, set signal ranges A and B or C and D via DIP switches S2-3 and S2-4.
Note
●
Make sure that the same analog signal type is set on each CompTrol Interface (see “Table 6:
Analog signal type” on page 19).
