Remark:
To break off communication with the VELBUS system, set the address on ‘00’ so no status modifications will
be reported. All learned push buttons must be deleted (see learning mode) so no instructions will be sent over
the VELBUS to control the push button indication leds.
In the other case, de relay module will cause a bus error with every status modification.
Remark: For connection between the modules, use twisted pair cable (ex. EIB 2x2x0.8mm2, UTP 8x0.51mm -
CAT5 or other). Use minimum 0.5mm² cable. For long wiring (>50m) or if a lot of modules ( > 10) are
connected to one wire, use 1mm² cable.
Connect the bus (mind the polarity) to the module.
