1INTRODUCTION
1.1 KLIC-SG vT
KLIC-SG vT from Zennio is a gateway that enables full-duplex communication between
the KNX home automation system and indoor range Samsung air-conditioning
systems through the 2-wire connection provided by the latter.
Because of this bidirectional communication, the air conditioning system can be
controlled from the home automation system in the same manner as it is through its own
controls. Moreover, the actual status of the unit can be monitored and periodically sent
to the KNX bus to inform other devices.
The most outstanding features of KLIC-SG vT are:
Bidirectional control of indoor Samsung A/C units (IDU) through the
connection wires provided F3/F4.
Control of the main functions of indoor Samsung A/C unit: On/Off,
temperature, mode of operation, fan speed, etc.
Error management to handle specific error codes from the A/C unit itself as
well as any communication issues that may arise.
2 analogue-digital inputs, for the connection of temperature probes, motion
detectors or binary pushbuttons or switches.
10 customisable, multi-operation logic functions.
Up to five scenes.
Heartbeat or periodic “still-alive” notification.

1.2 INSTALLATION
KLIC-SG vT connects to the KNX bus via the corresponding built-in terminal (5). Once
the device is provided with power from the KNX bus, both the physical address and the
KLIC-SG vT application program can be downloaded.
This device does not need any external power as it is entirely powered through the KNX
bus.
The remaining elements are described next.
Prog./Test button (2): a short press on this button will set the device into the
programming mode, making the associated LED (1) light in red.
Note: if this button is held while plugging the device into the KNX bus, the
device will enter into safe mode. The LED will blink in red every 0.5 seconds
Analogue-Digital Inputs (4): input ports for the stripped cables of external
elements such as switches, motion detectors, temperature probes, etc.
F3/F4 Communication (3): 2-wire communication cable that will connect
KLIC-SG vT to the A/C unit. The other end of the cable, therefore, is intended
to be connected to the F3/F4 connector in the PCB board of the internal unit.

Important: KLIC-SG vT is not compatible with Samsung wired remote control.
For detailed information about the technical features of KLIC-SG vT, as well as on
security and installation procedures, please refer to the device Datasheet, bundled in
the device packaging and also available at www.zennio.com.
1.3 START-UP AND POWER LOSS
Depending on the configuration, some specific actions will be performed during the
device start-up. The integrator may set up an initial status to be sent to the A/C unit after
the bus power restored, as well as the sending of certain objects to the KNX bus, as
described in later sections.
On the other hand, when a bus power failure takes place, the device will interrupt any
pending actions, and will save its state so it can be recovered once the power supply is
restored.

2CONFIGURATION
2.1 GENERAL
The general configuration of the device consists in enabling the specific functionalities
that will be required during normal operation:
Heartbeat or periodic “still-alive” notification.
Inputs.
Logic functions.
A/C gateway.
The latter entails all functions specific to KLIC-SG vT, i.e., all the functions related to
interfacing with the A/C unit and to the management of the climate control system.
ETS PARAMETRISATION
After importing the corresponding database in ETS and adding the device into the
topology of the desired project, the configuration process begins by entering the
Parameters tab of the device.
The General screen is shown in the first place, containing the following parameters:
Figure 3. General.

A/C Gateway [enabled]
1
: enables the “A/C Gateway” tab in the tree on the left.
For more information, see section 2.2.
Inputs [disabled/enabled]: enables or disables the “Inputs” tab in the tree on
the left, depending on whether the device will or will not be connected any
external accessories. For more information, see section 2.3.
Logic Functions [disabled/enabled]: enables or disables the “Logic Functions”
tab in the tree on the left. For more information, see section 2.4.
Heartbeat (Periodic Alive Notification): this parameter lets the integrator
incorporate a 1-Bit object to the project (“[Heartbeat] Object to Send ‘1’”) that
will be sent periodically with value “1” to notify that the device is still working
(still alive).
Note: the first sending after download or bus failure takes place with a delay
of up to 255 seconds, to prevent bus overload. The following ones match the
period set.
Figure 4. Heartbeat.
Regardless of the above parameters, the following objects are available by default:
“[AC] On/Off” and “[AC] On/Off (Status)”: allow switching on (value “1”) and
off (value “0”) the A/C unit or reading the current status, respectively.
“[AC] Temperature Setpoint” and “[AC] Temperature Setpoint (Status)”:
allow setting the desired temperature setpoint or reading the current value,
respectively. See section 2.2.1 for further options.

The default values of each parameter will be highlighted in blue in this document, as follows:

“[AC] Mode” and “[AC] Mode (Status)”: allow setting the desired operation
mode (either Automatic, Heating, Cooling, Fan or Dry) or reading the current
mode, respectively. See section 2.2.1 for further options.
“[AC] Fan: Percentage Control” and “[AC] Fan: Percentage Control
(Status)”: allow establishing desired fan speed or reading the current fan
speed, respectively. See section 2.2.2.
Several error objects. See section 2.2.5.

2.2 A/C GATEWAY
2.2.1 CONFIGURATION
KLIC-SG vT allows controlling and monitoring an air-conditioning unit in the same way it
would be through the wired remote control it is provided with.
Through the KNX bus, KLIC-SG vT can be sent orders to control the following basic
functions of the air conditioning unit:
On/Off switch of the air-conditioning unit.
Operation mode: automatic, heating, cooling, fan and dry.
Temperature setpoint, which can be modified within a 16-30ºC range.
Fan speed: 3 or 4 levels, depending on the model of the A/C unit.
Moreover, KLIC-SG vT allows configuring several advanced functions:
Simplified Operation Mode, which allows switching between heating and
cooling operation modes by means of a 1-bit object.
Fan, which allows advanced configuration of the ventilation, see section 2.2.2.
Temperature measured by the AC unit, which allows enabling an object
which provides the value of the internal temperature probe. The automatic
sending can be configured based on: a period of time, a change in value or a
combination of both.
External reference temperature, which allows enabling an object to use an
external reference temperature, provided by a temperature probe.
Setpoint limits, to restrict the range for the temperature setpoint.
Automatic off, which allows an automatic and temporary switch-off of the unit
(after a pre-established delay, if desired) when the communication object
associated to this function is triggered due to a certain event.

Initial configuration, which allows establishing the desired initial parameters
for the state of the A/C unit after programming or restarting the device.
Scenes, which allows defining predefined climate control environments, to be
sent to the machine on the reception of scene orders from the KNX bus.
Operation time, provides in hours and/or seconds the A/C unit operating time.
Wireless Remote Control Restriction, which allows to disable wireless
controller.
Filter, which allows to know the filter status of the A/C Unit.
Ionizer, which allows to activate the air purification function.
These functionalities imply changes in the state of the A/C unit, which therefore notifies
KLIC-SG vT periodically about the current state. When KLIC-SG vT is notified about a
change, it updates the status objects and sends them to the KNXbus. In addition, KLIC-
SG vT provides an error management function (see section 2.2.5), which allows
sending messages to the KNX bus in case the A/C unit reports any errors.
Important: the functionality parametrised in KLIC-SG vT shall match the available
functionality offered by the IDU, to prevent potential undesired behaviours.
