This
cascade
of
2
dual
function
boilers
leads
to
better
year-round
economics
as
a
result
of
its
higher
modulation:
low
power
consumption
in
the
summer
period
while
providing
higher
power
in
winter
time.
For
hot
water
production
the
boilers
work
in
parallel
(see
diagram
on
24
page)
and
for
heating
they
work
in
a
cascade.
Regulation
system
Control
Unit
works
with
maximum
8
boilers
of
this
type,
providing
regulation
of
3
heating
circuits
at
the
same
time
(with
a
maximum
of
2
mixing
heating
circuits).
If
there
is
a
need
of
more
heating
circuits,
it
is
possible
to
add
another
Control
Unit
(for
an
extra
2 additional heating circuits).

The diagrammes presented on these pages are an initial proposition and should not be used as the final design proposal, which should be made including detailed information about the building and premises.
