What can we improve?



Eaton xComfort

This guide will help you to connect the Eaton (former Moeller) xComfort Communication interface (CKOZ-00/03) - for connection to IP Symcon - and the Eaton xComfort Communication interface (CKOZ-00/01) - for programming the system in the Eaton comfort mode - to your computer as quickly and easily in order to create the conditions to use IP-Symcon to cover a variety of applications.
Alternatively, the connection of a Eaton USB gateway or LAN gateways to IP Symcon is possible. The Eaton xComfort radio system enables the monitoring of windows, air-conditioning and lighting systems as well as many other building control functions automatically. The system can be installed later without any installation of new lines. The system is bidirectional, that all the sensors and actuators (switches) can communicate with each other, because each of them contains a transmitter and a receiver unit.

List of supported devices:

Radio switching
Radio dimming
Radio binary input
Radio room controller
Radio room controller with Eco Switch
Radio room controller with moisture
Radio Shutter
Radio push button
Radio remote control

Step 1: Design

Remove your device from the package and place it in a location that is suitable for your purposes. Pay attention at the installation that your device is near by a PC because it must be connected via a cable. On the other hand the device should not be too far from your relevant actors because they must be reached by radio.

Step 2: Connection

To connect the Eaton Xcomfort system with IP Symcon, an appropriate gateway is required. In our example, it is the communications interface CKOZ-00/03. The programming interface CRZ-00/01 for the comfort mode is not suitable, but is also required, because it is used for programming the system in the comfort mode of Eaton.

When using the RS232 port it is important to note that additional power from the USB port must be supplied. This is possible via an adapter (230V-> USB).

The programming interface CRZ-00/01 can also be connected via the USB interface (optional cable: RS232->USB) or via the RS232 port. Connect the power plug and then connect it to the power supply. The socket for the hollow plug is located on the programming interface.

Step 3: Installation

If you have connected your equipment correctly, then this is now connected to your PC. Click on the Start icon of your Windows PC, then click on "Control Panel", on "Hardware and Sound" and then "Devices and Printers". There look for "Prolific USB-to-Serial Comm Port". In the brackets behind it, you will find the port (e.g. COM4) which should remember (or write down), because you will need this information in a moment.

Now download the latest version of Eaton firmware / MRF Software and install it. Then open the newly installed software. Then click on "Edit" and "Options", select the correct port (e.g. COM4) and set the ticks that fit for you.


Now click on the top tab "Gateway" and then on "Scan". Your system can now be programmed in the comfort mode.

Step 4: Adding secondary units

With the Eaton firmware you can easily integrate your secondary devices of Eaton (e.g. adapter, room controller, remote control, etc.) in your system.
Click on the upper tab on "Actions" and then twice on "Scan".
First it is searched for the main supplied devices. If necessary, you must go to scan in the vicinity of the secondary device, if it is not in the immediate coverage area.

If all main supplied devices have been scanned, click on "Continue to battery-powered devices." Now you have to press the battery-powered devices, so that a connection can be established to the gateway. Once this is done, click "Finish". You will now be prompted to enter a password. Enter as password "0000" and confirm it.
Now, click on the upper tab on "Actions" and then "Scan reception quality ..." and then again on "Scan".

If there are displayed devices with question marks, so you can delete them safely because all of your secondary device already should be associated with another symbol. To do this click with the right mouse button on the icon to remove and then left-click on "Remove". Then click first on "Yes" and then on "No".
Renamings are possible with a click of the right mouse button and then on "Rename".

Now your devices are displayed in the Eaton firmware. Now click on the pencil icon and connect your devices via virtual pencil with the gateway and click each time on "OK". Next, click under "Actions" on "Download changes". In order that IP-Symcon knows later, what is for example on data pointm 1 or on data point 2, you have to click with the right mouse button on the gateway, and then use the left to click on "Create data point list" and save those. Finally, you will save, as known from Windows, the whole project. Now you can close the Eaton firmware.

That's a wrap! Now you can finally turn to IP-Symcon.

Step 5: Connection of Eaton xComfort with IP-Symcon

After installing the softwarea with your user name and keys (received via e-mail from IP Symcon), you can now connect your Eaton xComfort devices with IP-Symcon.

To do this, open the IP-Symcon console (on your desktop). Then connect to one of the IP-Symcon server. Then click on "Create Configuration" and go to "xComfort Configurator". Click twice on "Next" and again once on "OK" and then on the gear (bottom left). The warning "No HID device selected/found" appears. Let it not trouble yourself. To create a HID device, click the "New" icon. It is to the right of the gear (bottom left) and then click on "HID", twice on "Next" and then click "OK".

Now click on "Welcome" (bottom left) and under "WebFront" on "Open WebFront". Your browser will then open the interface of IP-Symcon and you can for example turn on or off your living room lights.

Congratulations! The first steps for an automated home are done.

Tips & Tricks

  • New versions of the firmware/ MRF software can be found here:
    Eaton Downloads
  • The gateway is compatible with all standard USB-> LAN converters (e.g. Flint, Lantronix).
  • State variables are not routed from the Eaton Xcomfort system. This means that you need to position your gateway to a place where all relevant devices are within range.
  • You can use in IP-Symcon multiple gateways simultaneously and also send commands via scripts. It is common to place on each floor a gateway.
  • Only from the RF version 9.2 (approx. July/2008) the "Acknowledge" sent via the protocol level are evaluated. In previous releases, the system can not tell whether a command has been successfully delivered to a device. The RF version is a hardware upgrade, and should not be confused with the FW version that can be updated via software.
  • The new thermostat ECI LAN gateway or a USB Gateway requires at least firmware 2.6 and RF version 9.2. If the device is too old, the following error message displayes in the message window: Invalid RF firmware revision
