(1) The DHW flow capacity depends on the supply temperature, permissible return temperature and
pressure of the distribution network. By means of a flow restrictor in the Mains cold water fitting on
the plumbing bracket, the maximum DHW flow rate can be tuned to these external factors.
(2) The HIU should be mounted on a standard plumbing bracket (Supplied with the Digi Unit).
