TECHNICAL DATA
Air conditioning
In this mode, the system works both to produce DHW and to cool
the room.
e 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).
In this mode the protection functions available in stand-by mode
such as the antifreeze function etc are also guaranteed.
Air conditioning and room cooling in progress mode

From here on, the system works automatically. If there are no re-
quests (room central heating, DHW production or cooling), the
s y s t e m g o e s i n t o t h e “ s t a n d - b y ” f u n c t i o n .
Each time the outdoor unit ignites, the display shows the corre-
sponding symbol (8) with the corresponding power scale (10).
Operation with external probe
e system is set up to use the outdoor unit external probe or an
optional external probe.
With the external probe connected, the system ow temperature
for room heating and air conditioning is managed by the external
probe based on the outdoor temperature measured (Parag. 1.16).
You can change the ow temperature by choosing the oset value
in the specic user menu.
Dehumidify
If the system is coupled to a humidistat (optional) or a humidity
temperature sensor or a remote zone panel (optional), you can
m a n a g e t h e r o o m h u m i d i t y i n s u m m e r a i r c o n d i t i o n i n g m o d e .
– If coupled to a humidistat, set the degree of humidity on the hu-
midistat itself (see the instruction booklet).
– If coupled to a humidity temperature sensor, set the humidity
percentage in the relative user menu.
– If coupled to a zone remote panel, set the humidity percentage in
the relative user menu of the control panel or directly in the
menu of the panel (see instruction booklet).
Air conditioning and Dehumidication active mode

In central heating or cooling request mode, if the tem-
perature of the water in the system meets the request, the
system can work simply by activating the circulator
pump.
