Description

The KD300 display and control panel is a device from the Giacoklima
series, designed for use in Giacomini systems for floor or wall-fitted radiant
heating and/or cooling technology combined with the KM203 control and
supervision unit, K481 or K483 environment thermostats, the KPM20 unit and
other communicating devices with compatible protocols.
The KD300 display device is a terminal designed for centralising, viewing
and control functions, and can only be used in combination with the KM203
controller which represents the local interface. The KD300 is equipped with
a graphic panel sensitive to touch; touchscreen: with a simple stroke of the
surface of the panel, users can navigate the menus and access all of the
system functions. The number of areas and the type of information managed
by the system are controlled by the KM203 control and supervision unit.

Main characteristics

• Installation of GEWISS GW 24237 wall-mounted recessed box
• Safe low-voltage power supply (SELV) from KM203 control and supervision unit
• 1 RS485 input for connection to KM203 control and supervision unit
• Touch-sensitive graphic panel, with 320x240 pixel matrix, resistive-type
touchscreen, dimensions 3,5", black and white.

Functions

The KD300 graphic panel allows user to manage the following system
functions centrally:
• Centralised switchover of SUMMER/WINTER operation mode for all
connected devices (max 32 devices)
• View, edit and set the desired temperature and centralised recall attenuation
of a maximum of 16 K481 or K483 environment thermostats or K485 blind
probes, connected to the Giacoklima system bus.
• Insert and modify events for 4 programme schedules on a weekly basis
(CRONO), using the KM203 controller
• View and edit analogue maintenance parameters, to be configured
according to the system (maximum of 18 analogue parameters)
• View digital maintenance parameters, to be configured according to the
system (maximum of 18 digital parameters)
The KD300 graphic panel also incorporates the following functions:
• Date and time settings through the KM203 controller
• User customisation of the name given to the area controlled by a given
environment thermostat
• Multilingual support for the menu options. The languages provided are
ITALIAN, ENGLISH, SPANISH and PORTUGUESE
• Setting of display contrast - choose from 5 pre-defined values
• Setting of backlight timer - choose from one of 4 values: backlight always
on, backlight switches off 30 seconds after last use, 1 minute after last use,
and 2 minutes

Signal control elements

All the control and signal elements are operated using a touchscreen, and
can be activated by touching the relevant area of the display: see the control
panel User Manual for a description of the navigation menus and available
functions.
The display is organized across the top of the device, with a fixed band,
and on the left side containing the menu bar, which is always active, with a
maximum of 4 menu functions depending which screen your are using. The
central pane is dedicated to the area variables: the setting buttons allow the
user to vary the parameters set.
When the KD300 is switched on, the synchronisation of the configuration
with the KM203 controller takes place: This operation lasts 20-30 seconds
and can be viewed on a progress bar which is updated constantly until the
operation is complete. If no communication with the KM203 controller takes
place, the configuration phase is not completed.

Electric connections

On the rear of the KD300 panel, there is a 4-pole polarised removable terminal,
which should be used to carry out the connection with the KM203 control
and supervision unit: through the RS485-type interface, the exchange of data
and transfer of power to the device takes place. The maximum lenght of the
connection cable is 1000 m when a protected cable is used. It is advisable to
use a 4-pole protected cable with a minimum 0,25 mm
per conductor.

Warning.
Ensure that the electric connections with the KM203 control and
supervision unit are carried out correctly.
In addition, ensure that the synchronisation phase which occurs after
the device is switched on is completed.
If the synchronisation is not completed it will not be possible to
use the KD300 to view the information and to manage the system
centrally.
