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 outdoor
unit instructions booklet.
– Press the button (1) until the display switches on. The system
now goes back to the state prior to switch-off. (During ignition,
the display shows in sequence: display segments all lit, parame-
ter A011, parameter A013).
– If the indoor unit is in stand-by, press the button (1) again to ac-
tivate it. If this is not the case, go to the next point.
– Then press the button (1) in sequence and set the system to sum-
mer , winter , or air conditioning position
Summer
In this mode, the system only works to produce domestic hot wa-
ter, the temperature is set using the buttons (4) and the corre-
sponding 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 wa-
ter 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
.
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 central heating temperature is regulated via buttons (5) and
the relative temperature is shown on the display by the indicator
(14).
From here on, the system works automatically. If there are no re-
quests (room central heating, DHW production or cooling), the
system goes into the "stand-by" function.
Each time the outdoor unit ignites, the display shows the corre-
sponding symbol (8) with the corresponding power scale (10).
