Installation notes
NOTE
The correct dimensioning of the system components is crucial for the correct functioning of the
control loop. Please take this data from the ROPEX application report.
NOTE
In order to enable a good and stable control, additional resistances (fuses, long lines, plug con-
nections, ...) must be avoided in the secondary circuit.
Additional resistances influence the control and can make the system prone to errors, in the
long term.
