1.1 Intended use
In the event of inappropriate or improper use,
damage to the product and other property
may arise.
This product is a system component that en-
hances the system's functionality. A control
controls and regulates the functions via an
eBUS interface.
Operation is permissible with the following
control only:
–VRC 700/VRC 720
Intended use includes the following:
–observance of accompanying operating,
installation and maintenance instructions
for the product and any other system com-
ponents
–compliance with all inspection and main-
tenance conditions listed in the instruc-
tions.
This product can be used by children aged
from 8 years and above and persons with

ducts to a maximum of 2.5 cm to prevent
short circuits.
▶Lay the lines correctly.
▶Use the strain relief.
4. Strip the outer sheathing of the line, without damaging
the sheathing on the connecting wires.
