7.11 Cold water throttle disc
Note
The installed cold water throttle disc can be replaced by
a corresponding throttle disc if required (see table
below). The colour indicates the maximum inserted
volume flow.
A cold water throttle disc is located in the connection between the
cold water connection of the volume control valve and the strainer.
The throttle disc limits the amount of cold water to the heat
exchanger and prevents the hot water supply from exceeding the
calculated volume.
