Assembly
The VR 68 solar module is mounted on a wall near the
corresponding functional units.
The adjustment of all required parameters is carried out
using the controller VRC 430 or VRC 430f via eBUS.
All connections for the associated functional units
are established directly at the VR 68 solar module via
ProE terminals.

Note!
Depending on how the solar heating system is
configured, additional feed and cylinder sensors
may be required.
Only the standard sensor VR 10 from the
Vaillant accessories programme should be used.
The heating control using Vaillant components
is matched to the sensor characteristic curve
of the VR 10.
