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.

[L] Minimum bypass length
[D] Piping diameter
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.
