9.10 DHW circulation connection
DHW circulation is not recommended for reasons of poor energy
efficiency. If DHW circulation is required due to unfavourable pipe-
work or for reasons of convenience, you must install the DHW cir-
culation in accordance with applicable standards. To reduce pump
runtime and energy demand, we recommend imposing time and
temperature controls on activation of the DHW circulation pump.
The DHW circulation connector is located at the back of the appli-
ance (see chapter "Specification / Dimensions and connections").
A DHW circulation pump can be found in our range of accessories.
