Configure DHW charging
2707Z30
If you want DHW charging controlled
directly by the central apartment unit,
activate the required DHW plant com-
ponents (DHW sensor, pump / valve,
electric immersion heater).
If you require external DHW heating
controlled remotely via KNX TP1,
activate ”Operation external DHW“.
If there is a request for DHW, the room group pumps are not put into
operation. For this reason – from the hydraulics point of view – DHW
must always be installed upstream of the room groups.
The type of DHW heating depends on the installed DHW components accord-
ing to the following table:
DHW

valve
