10.2.3 3-position or modulating mixing valve
Mixing valve control can be provided either with a 3-position or DC 0…10 V actuator.
The type of actuator used is to be selected via "Extra configuration".
The output is to be activated via "Extra configuration":

10.2.4 Pump control
All DHW pumps offer the same choices as any other pump in the controller.
Supervision is also possible for an individual pump; optionally, every DHW pump can
be a twin pump. For that, the respective outputs must be configured.
For more detailed information, refer to section 5.8 "Pump control and twin pumps".

10.3 Operating modes and setpoints
10.3.1 DHW operating modes
The DHW operating mode defines the setpoint at which the storage tank or the flow
temperature is maintained.
Consumer control (optional) has a direct impact on the DHW temperature in the
consumer network. As a result, the settings made here will probably not be noticed by
the DHW consumer, or only with a certain delay.
