Bosch 8738209124 AWB 17 Heat pump inside module Doesn't apply

The indoor unit is used to distribute the heat coming from the heat pump to the heating system and the hot water tank.
The circulation pump in the indoor unit is speed-controlled so that the speed is automatically reduced if necessary. Thus, the power consumption is reduced.
If the heat demand is higher at low outdoor temperatures, an auxiliary heater may be required. Additional heater can be integrated or external and can be switched on or off via the operation of the indoor unit. If the heat pump only covers part of the energy requirement for the heating system, the lack of heating power is supplemented by the auxiliary heater. When the heating system covers the required energy again, the additional heater is switched off automatically.

AWB
If the heat pump COMPRESS 7000i AW is combined with the internal unit AWB and is also intended to generate hot water, an external auxiliary heater and, if necessary, an external hot water storage tank must be connected. The heater and warm water are then exchanged via an external 3-way valve. The indoor unit has a mixer. This controls the heat from the external additional heater that is started as required.
