can
be
configured
so
that
a
photovoltaic

to
be
1).
When
the
contact
is
closed
(activation
by

plant),
the
tank
setting
temperature
TS1
is
increased
to
the
max
possible
value,
according
to
the
settings
of
the
parameter
P.20.
-
P.20
=
0
(default),
the
temperature
value
introduced
manually
is
compared
with
the
maximum
admissible
temperature
value
given
by
the
climatic
curve,
and
then
the
unit
will
operate
according
to
the
highest
one
of
the
comparison
between
both
values.
-
P.20
=
1,
the

flashes.
11.5.6
Anti
‐
freeze
protection
If
the
unit
is
switched
off
but
still
under
voltage,
and
the
tank
temperature
drops
below
5°C;
the
electric
heater
is
forced
to
work
until
reaching
the
same

at
10°C.
In
this
case
the
