In
the
configuration
pages
on
the
chronothermostat
colourful
time
‐
lines
appear:
the
blue
time
‐
line
indicates
normal
operation,
the
green
time
‐
line
indicates
the
economical
operation,
the
red
time
‐
line
indicates
the
time
in
which
the
legionella
cycle
it
is
programmed
(thus
the
machine
in
that
condition
may
be
active
even
if
the
scheduler
is
set
to
Off).

WEEKLY
PROGRAMMING
FAN
COIL
ZONE
In
a
similar
way
to
the
scheduling
of
chillers,
a
weekly
program
of
each
zone
can
be
set
(independently
between
summer
and
winter),
with
minimum
steps
of
15
minutes.
The
possible
settings
are:
•
Off
zone;
•
Normal
operation
zone
(normal
ambient
set
‐
point);
•
Economical
function
zone
(economic
ambient
set
‐
point).
Going
in
"Summer
Zone"
or
"Winter
Zone"
the
list
of
all
zones
set
is
shown.
At
this
point
you
need
to
choose
the
area
you
want
to
set;
the
configuration
procedure
on
the
chronothermostat
is
then
equal
to
that
one
previously
reported
for
the
chiller.
The
features
and
the
functionalities
of
the
page
are
identical
to
those
already
described.

WEEKLY
PROGRAMMING
SANITARY
WATER
PRODUCTION
In
a
similar
way
to
what
is
reported
for
the
settings
on
the
chronothermostat
of
chillers
and
fan
coils,
you
can
define
when
to
enable
the
production
of
sanitary
hot
water
(by
setting
the
individual
days
of
the
week,
with
a
minimum
step
of
15
minutes).
The
settings
that
you
can
do
are:
•
Normal:
Enable
function;
•
Off:
Disabled
function.
To
set
the
programming,
go
to
"
Programs
"
‐
>
"
Sanitary
”
(the
word
"
Sanitary
"
appears
only
if
you
have
enabled
the
sanitary
mode:

=

).
The
procedure
for
configuring
the
programmable
chronothermostat
is
therefore
similar
to
those
described
above,
with
the
only
difference
that
the
choice
of
the
operation
is
only
between
"
Normal
"
and
"
Off
"
(see
figure
below).

In
the
period
when
the
function
is
active,
the
machines
enabled
to
produce
sanitary
water
are
placed
in
the
seasonal
operation
of
the
plant
scheduled
by
the
plant
scheduler
with
the
addition
of
the
sanitary
mode,
that
is,
respectively:
•
Summer
+
sanitary
•
Winter
+

•

you
can
program
the
hours
of
the
individual
days
of
the
week
for
activating
the
cycle
of
anti
‐
legionella
disinfection.
You
select
only
the
starting
time
(with
15
minutes
steps),
since
the
duration
of
the
cycle
is
defined
by
a
parameter
with
maintainer
access
rights
(System

).
To
carry
out
the
programming
you
must
enter
into
“
Programs
”
‐
>
“Legionella

the
procedure
is
simple
because
you
have
to
select
only
the
starting
day
and
hour
for
the
cycle
(see
Figure
below).
