4.5.1
Remote links
The equipment is designed to be connected to
other remote energy systems (photovoltaic ).
The user interface has two digital inputs with the
following functions:
Digital 1
: not used.
Digital 2
: Input from photovoltaic system.
The “Green” function is enabled when a free
contact is established between terminals 31
and 32 (cable: white/green). This function
exploits any overproduction of electricity and
it increases the temperature of the water in the
storage tank until it reaches the temperature
set by the user (70°C default temperature).
4.5.1.1
Remote link mode
As regards links to digital inputs, the equipment is
provided with an additional 4-core cable that has
already been linked to circuit board of the user
interface (placed inside the equipment Fig. 12).
The remote links to any energy systems must be
carried out by a qualified installer (junction boxes,
terminals and connection cables).
The following illustrations show an example of a
remote link (Fig. 10 e Fig. 11).
Fig. 11 – detailed example of a remote link
To access the 4-core cable for remote connection
it is necessary to remove the upper cover of the
boiler, and take the cable outside through the
dedicated opening, that is already present on the
back cover, as indicated in Fig. 12.
