11.2 System solutions
The outdoor unit and the indoor unit may only be installed according to
the manufacturer's official system solutions.
Deviating system solutions are impermissible. Liability is voided in the
case of damage and problems resulting from impermissible installation.
Some system configurations require accessories (buffer cylinder, 3-way
valve, mixing valve, DHW circulation pump). If a heating circuit pump
(PC1) is installed, this is controlled by the controller in the indoor unit.

The bypass must have an outer pipe diameter of 22 mm (Cu) and be
installed between the supply and return. The bypass must be installed
close to the indoor unit (AWES), and no more than 1.5 m away from it.
