Modifying the operating mode for the indoor unit:

The operating mode of the Indoor unit (or group of indoor units) managed by the wired panel can be modiﬁ ed using the MODE

button; every time it is pressed thereafter will switch between one mode and the next (following the sequence indicated below);

available modes are:

Auto ( ): This function automatically selects the most suitable operating mode based on the indoor temperature; this func-

tion does not allow any modiﬁ cations to the setpoint (depending on the mode, default values will be chosen for hot and cold

settings, having respective values of 20°C and 26°C) while ventilation and functions such as “swing” (if available from the Indoor

unit model) are set as usual; while using this function, the icon for the selected mode will be displayed (hot or cold) as will as

the Auto mode icon.

Cooling ( ): This mode allows room air to be conditioned until the temperature chosen as the operating setpoint is reached;

this temperature may be between 16°C and 30°C;

Dehumidiﬁ cation ( ): This mode, in a similar way to the cooling mode, allows room air to be dehumidiﬁ ed: the operating

temperature may be between 16°C and 30°C;

Ventilation Only ( ):

This mode does not allow any modiﬁ cations to the setpoint, and does not cool or heat the room air; however,

it allows ventilation to be set as usual as well as the swing function (if available on the Indoor unit model);

Heating ( ): This mode allows room air to be heated until the temperature chosen as the operating setpoint is reached; this

temperature may be between 16°C and 30°C;

Operating logic for AUTO Mode ( ):

(A) (B)(C)

Indoor temperature (TEMP)

22°C 26°C

If TEMP ≤ 22°C, Heat Mode will be activated with a setpoint

of 20°C (setpoint can be chosen from parameter P38)

If 22°C < TEMP < 26°C, the last active mode will

be activated (but if this is the initial start-up, then

Ventilation Only mode will be selected)

If TEMP ≤ 26°C, Cool Mode will be activated with a setpoint

of 26°C (setpoint can be chosen from parameter P37)

WARNING: AUTO mode is

ONLY available on the Indoor unit

set as MASTER.
