6 Mounting

For mounting the CCU3 to a wall using the supplied screws and plugs, please proceed as follows:

Select a suitable mounting location on the wall, close to your router and a socket.

Make sure that no electricity or similar lines run at this location!

Use a pen to mark the positions of the two bore holes for the brackets (E) with a distance of 90 mm on the wall (see fig. 2).
Use an appropriate drill to make the 5 mm holes as illustrated.
Insert the plugs in the holes.
Turn the screws into the plugs so that they protrude from the wall by approx. 2.5 mm. Hang the device using the brackets on the back behind the screw heads.

7 Start-up

For set-up of the CCU3, an active Internet connection must be available. After successful set-up and configuration, operation can still be carried out also in case of an inactive Internet connection.

7.1 Installation

After installation, you can start up your CCU3. To do this, please proceed as follows:

Connect the CCU3 via the network connection (B) and the supplied network cable to your router (see figure 3).
Establish the power supply for your device via interface (D) and the supplied plug-in mains adapter (see figure 3).

If the device LED (A) lights up permanently blue, the CCU3 is ready for operation and you can continue the set-up.
You will find further information about the flashing behaviour in section “8.1 Error codes and flashing sequences” on page 46 .

7.2 Starting the WebUI user interface

The WebUI user interface offers a large number of configuration and control options for your Homematic and Homematic IP devices.
To enable local configuration of your devices and to control devices and connect them with each other or for using Central Control Unit programs, you must start and set-up the WebUI.
You can access the user interface via a web browser (see “5 System requirements” on page 36).
To call the WebUI in your web browser you will need the IP address or the DNS name of your CCU3. You can also use your router or the “NetFinder” add-on software to find out the IP address.

7.2.1 DNS name

As most routers support DHCP, the assignment within the network is carried out automatically. During start-up, the CCU3 tries to receive an IP address. When requesting the DHCP, the desired DNS name is transferred to the DHCP at the same time. The CCU3 uses the DNS name “ccu3webui”. If the DHCP server supports also the indication of a DNS name (e.g. Fritz!Box), the CCU3 WebUI can be called directly in the web browser via the URL http://ccu3-webui.

For secure connection, you can also use https://ccu3-webui to call the WebUI of your CCU3. Depending on the web browser used, different safety instructions are shown. Please enable access to the WebUI and confirm opening of the user interface via secure connection.

If the DHCP server does not support the indication of a fix DNS name, you will usually find the IP address of your CCU3 via the web interface of the router (see “7.2.2 Access to the IP address via the router” auf Seite 40).

7.2.2 Access to the IP address via the router

You can find the IP address of your CCU3 in the device list of your router. Therefore, you will need the MAC address of your CCU3. It can be found on the device sticker.
Depending on the router manufacturer, you will find the CCU3 in the following area of the router back-end:
– Netgear: Connected devices
– TP-Link: Network plan/connected devices
– FritzBox: Home network

Note the IP address of your Central Control Unit.
Enter the IP address into your web browser. The WebUI home page is opening.

Depending on the configuration, the IP address of the CCU3 can also be determined via the network area of the windows workplace.

7.2.3 Calling the IP address via “NetFinder”

Please make sure that the “Java” software is installed on your PC. If required, download the free software at www.java.com.

Use the “NetFinder” add-on software to display the IP address of your CCU3. To download the software, proceed as follows:

Open the website www.eq-3.com.
Download the NetFinder zip file in the download area and unzip the file at the desired location of your PC.
Open the NetFinder tool on your PC. The IP address of your CCU3 is displayed in the window.
Note the IP address of your Central Control Unit.
Enter the IP address into your web browser. The WebUI home page is opening.

7.3 Installation of the WebUI software

When starting the CCU3 for the first time, please update the software of your device via the WebUI. Please proceed as described and follow the instructions in the WebUI user interface.

Open the homepage of your WebUI. Therefore, please enter the IP address into your web browser.
Click on the button “Update”.
First click on the “Download” button to save the software files to your PC.
Accept the license agreement and click on “Install” afterwards.
Save the file on your PC.
Select the downloaded software via “Select file”.
Click on “Upload” to load the software to your Central Control Unit. This process may take a few minutes.
As soon as the software file is uploaded to your CCU3, accept the license agreement again and click “Install”.
Confirm the update via the button “Start update”. The software update is now in progress.

Once the software update has been carried out, you will need to register on the Central Control Unit again. The full range of functions will then be available for your Central Control Unit.

7.4 Teaching-in devices to the CCU3

Please read this entire section before starting the teach-in procedure.

Your Homematic and Homematic IP device can be conveniently controlled and configured or used in Central Control Unit programs using a software-based method. Therefore, they must be integrated into the system via the WebUI. To do this, please proceed as follows:

Start the WebUI user interface in the web browser of your PC.
Click the “Teach-in devices” button on the right-hand side of the screen.
To activate teach-in mode of the CCU3, click on the desired teach-in window (e.g. “Teach-in HmIP device”). The teach-in mode of the Central Control Unit will be activated. An information box shows how much teach-in time remains.
Activate the teach-in mode of the device, that you want to teach in. Please refer to the user manuals of the corresponding devices for further information.
Please wait until teach-in is completed.
If teaching-in was successful, the LED lights up green. If the LED lights up red, please try again.
After a short time, the newly connected device appears in the inbox of your WebUI.

Newly connected devices and the corresponding channels are ready for operation and configuration only after they have been configured in the inbox. You will find further information in the Homematic WebUI Manual, available for download at www.eQ-3.com.

8 Troubleshooting

8.1 Error codes and flashing sequences

the subsequent flashing behaviour.
Slow blue flashing| Connection to network is being established| Wait until the connection is established and the LED lights permanently blue.
Permanent blue lighting| Normal operation, connection to network is established| You can continue operation.
Fast yellow flashing| No connection to network or router| Connect the CCU3 to the network/router.
Fast blue flashing| No Internet connection| Please check the Internet connection and firewall settings.
Slow magenta flashing| Recovery system starts| Please wait shortly and observe the following flashing behaviour.
Fast magenta flashing| Update in progress| Please wait until the update has been completed.
Permanent red lighting| System not ready (at least one system component could not be started)| Please restart your CCU3. If a new error message please contact the support.
Permanent magenta lighting| Recovery system active| Please wait until the system recovery is completed.
Alternately blue and yellow flashing| Service message| Confirm service message (can be switched off via WebUI)
Alternately blue and red flashing| Alarm message| Confirm alarm message (can be switched off via WebUI)

If the device LED is not lit, the CCU3 cannot be started. If the LED does not light up after a minute, restart the system again. If after several attempts the system still does not start, please start the rescue system and install the update again.

8.2 Functional limitations

If the functional limitations or any behaviour that is described in the WebUI Manual occur, it may be caused by the settings of your web browser or additional security tools that are installed on your PC (e.g. anti-virus software, firewall or browser-protection add-ons).
In this case, you should include the IP address of your CCU3 into the exception list of your firewall or browser protection (exceptions are made for the Windows firewall). Furthermore, you should always call the IP address via the CCU3 (see “7.2 Starting the WebUI user interface” on page 39).

8.3 Duty cycle

The duty cycle is a legally regulated limit of the transmission time of devices in the 868 MHz range. The aim of this regulation is to safeguard the operation of all devices working in the 868 MHz range. In the 868 MHz frequency range we use, the maximum transmission time of any device is 1% of an hour (i.e. 36 seconds in an hour). Devices must cease transmission when they reach the 1% limit until this time restriction comes to an end. Homematic IP devices are designed and produced with 100% conformity to this regulation.
During normal operation, the duty cycle is not usually reached. However, repeated and radio-intensive teach-in processes mean that it may be reached in isolated instances during start-up or initial installation of a system. If the duty cycle is exceeded, this is indicated by one long flashing of the device LED, and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).

8.4 Recovery system

The recovery system is only required if the software of the Central Control Unit has been damaged. This can happen, for example, if the power supply is interrupted during a software update.
Via the LED (A) it is indicated, that the operating system of the CCU3 cannot be started any more (see “8.1 Error codes and flashing sequences” on page 46). In this case, a software update has to be carried out via the recovery system.

To start the recovery system, proceed as follows:

Unplug the cable of the power supply unit (D) of the CCU3 to disconnect the power supply. Wait for 5 seconds.
Press and hold down the system button (A) for at least 5 seconds, while plugging in the network cable for power supply.
Release the system button again.

The Central Control Unit now starts the recovery system. Meanwhile, the device LED (A) starts to flash magenta slowly.
As soon as the recovery system is completely booted up, the device LED permanently lights up magenta.
Entering the IP address of your CCU3 in your web browser will take you to the homepage of the recovery system.

Depending on the network infrastructure used, it may occur that the CCU3 is reached via another IP address during active recovery system than during normal operation, as DHCP is activated during the recovery system of the CCU3.

9 Maintenance and cleaning

The product does not require any maintenance. Enlist the help of an expert to carry out any repairs.

Clean the device using a soft, lint-free cloth that is clean and dry. Do not use any detergents containing solvents, as they could corrode the plastic housing and label.

10 General information about radio operation

Radio transmission is performed on a non-exclusive transmission path, which means that there is a possibility of interference occurring. Interference can also be caused by switching operations, electrical motors or defective electrical devices.

The range of transmission within buildings can differ greatly from that available in the open air. Besides the transmitting power and the reception characteristics of the receiver, environmental factors such as humidity in the vicinity have an important role to play, as do on-site structural/ screening conditions.

Hereby, eQ-3 AG, Maiburger Str. 29, 26789 Leer/Germany declares that the radio equipment type Homematic IP HmIP-CCU3 is in compliance with Directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following internet address: www.eq-3.com
