2.4 SYSTEM USE.

Before ignition, make sure the system is full of
water, checking that the pressure gauge needle
(6) points to a value between 1 and 1.2 bar and
make sure that the chiller circuit has been filled
as described in the condensing unit instructions
booklet.
- Press the button (1) until the display switches
on. The system now goes back to the state prior
to switch-off.
- If the hydronic module is in stand-by, press the
button (1) again to activate it. Otherwise, go to
the next point.
- Then press the button (1) in sequence and set
the system to summer ( ), winter (
heating/air conditioning ( ) position.
• Summer (
): in this mode, the system only
works to produce domestic hot water, the
temperature is set using the buttons (4) and
the corresponding temperature is shown on
the display by the indicator (14).
Summer and DHW heating in
progress mode
• Winter ( ): in this mode, the system works
both to product domestic how water and room
central heating. The temperature of the DHW
is always regulated via buttons (4), the central
heating temperature is regulated via buttons
(5) and the relative temperature is shown on
the display by the indicator (14).
Winter and room central heating in
progress mode
• Heating/air conditioning ( ): in this mode,
the system works both to produce DHW and to
cool the room. The temperature of the DHW
is always regulated via buttons (4), the cooling
temperature is regulated via buttons (6) and the
relative temperature is shown on the display by
the indicator (14).
Heating/Air conditioning and room

From here on, the system works automatically.

If there are no requests (room central heating,
DHW production or cooling), the system goes
into the "stand-by" function. Each time the
condensing unit ignites, the display shows the
corresponding symbol (8) with the correspond-
ing power scale (10).

The system is set up to manage two CAR

Attention: if the hydronic module is switched

•Operation with external probe (
system is set up to use the condensing unit
external probe or an optional external probe.
With the external probe connected, the system
flow temperature for room heating and air
conditioning is managed by the external probe
based on the outdoor temperature measured
(Parag. 1.9). You can change the flow tempera-
ture by choosing the offset value in the specific
user menu. If the CAR
change the operating curve using the controls
on it, selecting a value from "0 to 9" (See CAR
instructions). In this case, any settings made
2-3
on the hydronic module will not affect system
operation.
• Dehumidify ( ). If the system is paired with
a humidistat (optional) or a humidity temper-
ature sensor (optional), you can manage the
15
room humidity in summer air conditioning
mode.
- If paired with a humidistat, set the degree
of humidity on the humidistat itself (see the
instructions booklet).
- If paired with a humidity temperature sensor,
set the humidity percentage in the corre-
sponding user menu or, if there is a CAR
you can set it on the remote control itself from
the "S UR %" parameter.
