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 xed 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 conguration
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 conguration 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 mm2(23 AWG) section
per conductor.
Description
The KD300 display and control panel is a device from the Giacoklima
series, designed for use in Giacomini systems for oor or wall-tted 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.

• 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:

(CRONO), using the KM203 controller
• View and edit analogue maintenance parameters, to be congured
according to the system (maximum of 18 analogue parameters)
• View digital maintenance parameters, to be congured 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

KD300 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.
Warning.
Ensure that the power supply to the KM203 control and supervision
unit is suspended while connections are being carried out.

KD300
3,5" unit display touchscreen, for viewing system variables and setting
scheduled programmes, for a maximum of 16 zones. To be used in combi-
nation with KM203 series control and supervision unit. Options available: set
scheduled programmes; activate summer-winter switchover for the entire
thermoregulation system; personalise the names of the zones in question;
diagnose system faults and tune operational parameters; navigation menu
in Italian or English. To be completed with K489D recessed box. CE marked.
Installation
The KD300 touch-screen panel is a device designed to be used with a wall-
mounted recessed box; the shell is equipped with slotted holes for xing in
place. It is advisable to use the high-capacity K489DY003 box for modular
8-place (4+4) domestic series (Gewiss GW 24237).
The external dimensions of the recessed box (LxHxP) are: 131x129x53 mm.
The 4-pole terminal is positioned at the back of the device and can be
removed for connection with the KM203 controller.
To mount the device to the recessed box:
1- Prepare the cable for connection to the KM203 controller inside the re-
cessed box (unsheathing removes approx. 10 mm, 4 conductors stripping
approx. 4 mm) and attach it to the detachable part of the 4-pole terminal
2- Insert the detachable part of the terminal to the xed part which is located
on the rear of the device
3. Position the shell of the panel on the recessed-mounting box, insert the 4
xing screws provided into the holes on the box and tighten;
4. Using the slotted holes, adjust the horizontal alignment of the panel;
5- Position the cover plate on the frame of the panel and slot into position.
