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.

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.

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.

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:

S1 MASTER SLAVE PARAMETERS
These parameters allow setting the control unit for .NET conguration.
The architecture must, therefore, provide for the presence of a MASTER connected to
the S1 serial bus. You can set the following parameters:
TimeOut: maximum time with absence of communication between the MASTER and
the control unit.
Cong Slave:
•No: In this case, the control unit is independent and manages all the components
of the system.
•Master: In this case the controller is connected with .NET system including 1 Master
controller.
•Master_PC: In this case the controller is connected with .NET system including a PC
as system supervisor and 1 Master controller.
Clock Master: if the control unit is congured as SLAVE conguring:
•YES: The control units draws time-related information from the MASTER.
•No: The control unit is independent with its clock on board.

LOCKING THE LOW TEMPERATURE DEHUMIDIFICATION
Locking the dehumidication mode:
The dehumidication mode is locked if there are low temperature values and high
humidity values. In this way too cold air is prevented from coming into the room. This
is controlled through a threshold value based on DP (dew point).
The function is enabled by EN_CTRL parameter.
