1 INTRODUCTION
KLIC-MITTE
KLIC-MITTE from Zennio is a new gateway that provides full-duplex communication
between the KNX home automation system and Mitsubishi Electric Ecodan air-
conditioning and hot water management systems through the IT Terminal interface.
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-MITTE are:
Bidirectional control of Ecodan ME (Mitsubishi Electric) units through their IT
Terminal connector (CN105/CN92).
Control of the main functions of the Ecodan unit: On/Off, temperature, mode
of operation, etc.
Error management to handle specific error codes from the unit itself as well
as any communication issues that may arise.
Two analogue-digital inputs, for the connection of temperature probes,
motion detectors or binary pushbuttons or switches.
10 customisable, multi-operation logic functions.
Heartbeat or periodic “still-alive” notification.

INSTALLATION
Figure 1. Element scheme
KLIC-MITTE 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-MITTE 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 (3): input ports for the stripped cables of external
elements such as switches, motion detectors, temperature probes, etc.
Communication cable (4): cable with a CN105/CN92 connector that will
connect KLIC-MITTE to the unit. The other end of the cable, therefore, is
intended to be connected to the IT Terminal connector in the PCB board of
the internal unit.

Important: KLIC-MITTE is designed for FTC5 control systems. For other control
systems, that many functions are disabled must be taken into account. In addition,
certain parameterisations made in the device can be ignored.
For detailed information about the technical features of KLIC-MITTE, as well as on
security and installation procedures, please refer to the device Datasheet, bundled in
the device packaging and also available at http://www.zennio.com.
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 unit after
the bus power recovery, and whether certain objects should be sent to the bus after the
power recovery, 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.

2 CONFIGURATION
GENERAL
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.
ETS PARAMETERISATION
The “General” screen is shown in the first place, containing the following parameters:
Figure 3. General
Ecodan Gateway [enabled]1: entails all functions specific to KLIC-MITTE,
relating to communication with the Ecodan unit and management of the
climate and hot water control system. For more information, see section 2.2.
Inputs [disabled/enabled]: enables or disables the “Inputs” tab in the tree on
the left. 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) [disabled/enabled]: this parameter
lets the integrator incorporate a one-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).

The default values of each parameter will be highlighted in blue in this document, as follows:
[default/rest of options].

Figure 4. Heartbeat
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 sendings match
the period set.
Regardless of the above parameters, the following objects are available by default:
“[General] On/Off” and “[General] On/Off (Status)”: allow switching on
(value “1”) and off (value “0”) the Ecodan unit or reading the current status,
respectively.
Several error objects. See section 2.2.33.
“[Climate] Operation (Status)” and “[Climate] Allowed/Prohibited
(Status)”: allow reading the current state of the climate.
“[Climate] [Zone 1] Temperature Setpoint” and “[Climate] [Zone 1]
Temperature Setpoint (Status)”: allow setting the desired temperature
setpoint or reading the current value, respectively. See section 2.2.1 for
further information.
“[Climate] [Zone 1] Temperature Control Mode (Status)”: allows reading
the type of control that the unit performs (Flow/Room/Compensation Curve)
respectively. See section 2.2.1 for further information.
