DHW settings menu for fresh water station
If a fresh water station is installed and configured for the system, this
menu replaces the standard DHW menu.
Setting the DHW temperature ≥ 52 °C can lead to higher electricity cost
as the electric booster heater may be activated.
Menu item

[Off]: circulation off.
mode
[On]: circulation permanently on (by taking the start
frequency into account).

[6 x 3 minutes/h]: the DHW circulation pump goes into
operation once ... 6 times per hour for 3 minutes.
[Permanent]: the DHW circulation pump is permanently in
operation.
Circulation pulse
[Yes] | [No]: The circulation pump runs for 3 minutes as
soon as there is a short tap (2-10 seconds). The pump is
then blocked for 10 minutes.
