INDICATION
ON

OPERATION
You
can
set
a
digital
output
to
indicate
the
operating
mode
of
the
unit,
system
side
(the
digital
outputs
are
at
230V
AC,
therefore
they

control
a

free
contacts).
The
digital
outputs
are
set
when
the
value

is

The
output
is
active
during
summer
operation
while
is
disabled
in
OFF
mode
or
winter
mode.
During
sanitary
hot
water
production
and

mode,
the
output
keeps
the
setting
of
the

(winter
or
summer
mode).
