Error
Remedy
No Wi-Fi connection
The Wi-Fi signal from the Wi-Fi router is possibly not strong enough. Fit a Wi-Fi repeater.
Wi-Fi network not found
Hide function of the Wi-Fi-router is possibly switched on or broadcast function (transmitting the
SSID) is switched off. Temporarily switch the hide-function off or broadcast-function on.
This display
remains on
Wi-Fi network is possibly protected with “WEP64” protocol. This protocol is not supported.
Change the safety protocol of the router.
IP-address
There is no IP-address allocated by the router yet. This can take some time. It may be necessary to
manually allocate an IP-address in the router (
router manual).

network installed
Remove the controller from the wall plate, wait 10 seconds and then click the controller back onto
the wall plate. All Wi-Fi networks found are shown on the display (
section 4.6.3).

not shown
Connection to the server is broken. Wait until the connection is restored.
Serial number and access
code missing

also on the label on the back of the controller. If an app is used to log in, the serial number and the
access code can be shown in the app by going via the “Info” menu to the submenu “product
information”. If the serial number and the access code cannot be found, then contact the installer/
Bosch Group technical support.

the controller
Is the controller connected to the Internet (
section 4.6.3)? Are the serial number and the access
code input correctly? Please note, these are case-sensitive. There is possibly a delay in
establishing the connection. Wait for a few minutes.

There is no connection to the Internet server, wait until the connection to the Internet server is
restored automatically. Once started, the boiler can only be controlled manually, no time

point is reached in the time programme mode.

functionality may not yet be supported by the controller. The software is updated automatically,
this can possibly take a few days.
