SAFETY WARNINGS
Carefully read this booklet before starting and/or using the
appliance and keep it in an easily accessible place .
Contact the manufacturer's technical office at the numbers
indicated at the back of this booklet for consultancy or
special technical requests.
•WARNING
Installation and maintenance must be carried out only by
qualied personnel or else the guarantee will be void.
• Use only original spare parts: Failure to comply with this
instruction will make the guarantee void
SAFETY WARNINGS
DISPOSAL
According to the provisions of the following
European directives 2011/65/EU, 2012/19/EU,
and 2003/108/CE, concerning the restriction
of the use of certain hazardous substances in
electrical and electronic equipment, as well as
waste disposal.
The crossed out wheelie bins symbol on the equipment
indicates that, at the end of its useful life, the product must be
collected separately from general waste.
Therefore, at the end of its useful life, the user must take the
equipment to a designated electrical and electronic waste
collection point or return it to the dealer upon purchase of an
equivalent new product.
Appropriate dierentiated waste collection for subsequent
recycling, treatment and environment-friendly disposal of
the discarded equipment helps preventing possible negative
environmental and health eects and encourages recycling of
the component materials of the equipment.
Illegal disposal of the product by the user entails the application
of sanctions provided by the regulations in force.

At its maximum expansion it can manage:
8mixing systems (with analog servo motor)
64 zones with temperature and humidity sensor
64 total calls for dehumidication and integration
8air handling units with dehumidication

Moreover, it can be used in the following operating modes:
•AUTONOMOUS MODE: to be installed on systems with independent power production.
•SLAVE MODE: to be installed on systems with centralised power production. This conguration provides for the use of the
MASTER.NET control unit.

xx: number of mixing systems <=8
yy: number of controlled zones: each one having independent temperature and humidity controls <=64
a.: number of controlled air handling units (dehumidication, ventilation, air renewal and, integration) <=8
The WI project includes 2 product families:
WI-SA: stand-alone controller
WI.NET:control system with centralised energy production (through“Bus.NET”).
The illustrated manual describes all the possible operating modes.
NB: According to the conguration, the control unit can inhibit the display of some screens, since they do not have any meaning

Button Function
The alarm button has a red backlight and is activated when the control system detects an anomaly. Pressing the
button once will display the screen pertaining to the problem occurred. In the event of simultaneous alarms,
these can be displayed by scrolling through the screens using the UP and DOWN buttons. Pressing this button
again RESETS the alarms; should they still be present, the relative screens remain on display; otherwise the words
“no alarm” will appear and the red backlight will turn o.
Pressing the PRG button from the main screen displays the system time slot programming menu. Pressing the
PRG button in any other context, will allow you to scroll through the progression of the displayed views and the
various functions:
