Bosch Control
Remedy
The Wi-Fi signal from the Wi-Fi router is possibly not strong enough. Contact Wi-Fi provider, or
consider Wi-Fi repeater in some situations. Only compatible with "b" and "g" routers.
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.
Wi-Fi network is possibly protected with "WEP64" protocol. This protocol is not supported.
Change the safety protocol of the router ( router manual).
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).
Remove the Bosch Control from the wall plate, wait 10 seconds and then click the Bosch Control
back onto the wall plate. All Wi-Fi networks found are shown on the display ( section 4.6.3).
Connection to the server is broken. Wait until the connection is restored.
The serial number and the access code are both on the label on the front of these instructions and
also on the label on the back of the Bosch Control. 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 Thermotechnology Corp. Technical Support.
Is the Bosch Control 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.
A horizontal swipe across the display makes the touch screen inactive. The touch screen is the
locked for 15 seconds to be cleaned.
The touch screen may be locked in the App, check the App and unlock if necessary.
In the App, the temperature shown can be calibrated.
If there is detection for longer than 5 minutes, the screen goes off automatically. After this, the
screen can only be activated again by touching.
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 program
is available.
The Bosch Control uses the standard Wi-Fi protocol, so it is not possible to use a $-sign in the Wi-Fi
router password. Remove the $ sign from the router password.
Symbol disappears when the temperature is changed via the display or when the next switching
point is reached in the time program mode.
Straight out of the box, the latest software version may not be installed on the Bosch Control, as a
result functionality may not yet be supported by the Bosch Control. The software is updated
automatically.
Indication of one of the following messages: repeated ignition attempts, boiler gives maintenance
message. This relates to an information signal. The boiler runs normally.
The software is updated automatically and a continuous Internet connection is required for this.
If the router is not on continually, updates may be missed.
