Figure 1b: Floor arrangement diagram
The indicative diagram in figure 1b only illustrates the feed pipes of the individual user modules.
The heating plant inside the zone controlled by the module must be realised by feeding the heating elements according
to normal methods.
The storage boiler for the production of domestic hot water must be installed inside the home (or zone) service by the
module.
A stub of the mains water supply must be connected to the domestic hot water inlet connector of the storage boiler. The
storage boiler hot water outlet must feed all the user hot water take-off points.
