Change Wi-Fi network or new network

To log the controller onto a new Wi-Fi network or if the existing
network has a new password:
▶ Reset the controller ( section 7.3.2).
▶ Follow the step to set a Wi-Fi network ( section 4.6.3).

Troubleshooting
Fault messages from the boiler are visible on the
display and are sent automatically from the
controller to the app.
7.3.1 After a power cut
All settings are saved during a power cut. After the connection
is re-established with the Wi-Fi network, the settings will be
synchronised with the external server.
▶ Check the date and time setting
If a connection can not be made with a Wi-Fi network, the date
and time settings can be applied through a direct Wi-Fi
connection with the app from a smart device. Date and time are
automatically synchronised.

7.3.2 Reset controller
If the controller no longer works properly, it can be discon-
nected briefly from the wall plate and then re-attached
( fig. 7, page 28).
If this does not solve the problem, with the controller mounted
on the wall, the reset key ( fig. 18) can be pressed for a few
seconds to remove the fault. If the fault occurs again, then
contact your installer or the Bosch Group Technical Support
team.
Reset!
Using the reset key deletes all personal settings
and the Wi-Fi connection has to be set up again.
