WARNING!
If there is a short-circuit in a 230V/400V load, the contact of a relay
can fuse due to the high short-circuit current. Even the safety relay
can fuse if restarted before removing the short-circuit. This will
lead to steady state of the consumer. Switch off the automatic cir-
cuit breaker in the junction box. Send the device back to the facto-
ry for checking/repair.

3.4 Initial set-up with WLAN operation
NOTE!
Please have your personal WLAN password ready for set-up via WLAN.
During initial operation, the Connect Box must be connected to the existing WLAN.
1. Start the Connect Box by briefly disconnecting it from the power supply and plug-
ging it in again.
After it is switched on, the Connect Box searches for all available WLAN connec-
tions. The Connect Box then opens its own WLAN "CONNECT-BOX".
Note: This WLAN is only required for setting the Connect Box. It is only available
for 3 minutes once the "Connect Box" has been found by your Smartphone/Tablet.
Please perform the following steps (2-5) within these 3 minutes.
2. Please connect to the WLAN "CONNECT-BOX".
To do this, open the WLAN menu in your Smartphone/Tablet:
Settings WLAN Search WLAN
Connect to "CONNECT-BOX"
The password required for this is: "11111111"
Note: This WLAN does not have Internet access. Any warnings that your
Smartphone/Tablet is not connected to the Internet can be ignored or, if you are
prompted to do so, this message must be confirmed.
Note: Check that you are still connected to the WLAN "CONNECT-BOX".
Note: After a repeated connection with "CONNECT-BOX", the password may be
saved and does not have to be entered again.
3. On your Smartphone/Tablet, open the Internet browser (e.g., Safari or Chrome) and
open the following page in the address bar: "http://10.42.0.1"
4. Select your own home WLAN from the list and enter your personal WLAN password.
Then press "Save & Restart".
If your WLAN is not listed, check the WLAN signal strength!
After saving you lose the connection to the Connect Box, which can lead to an error
message in your browser.
Note: Remember to reconnect your Smartphone/Tablet to your home WLAN.
5. After saving the settings successfully, the Connect Box automatically connects to
your in-house WLAN and afterwards to the cloud server.
The sauna control unit gives the following feedback signals on these three process-
es via the buzzer:
1x beep: Settings saved.
Note: If this 1x beep is not heard, you may have taken too long or are too far away
from the Connect Box. In this case, you must start again from step 1.
2 x beeps: WLAN connection successfully established.
Note: If the 2x beeps are not heard, the Connect Box has not connected to your in-
house WLAN. You may not have enough WLAN reception or a wrong WLAN pass-
word. You may need to move the Connect Box to another location. Please check
both and start again at step 1.

Connection and initial set-up by service technician
Installation and Operating Manual / Version V 1.02 15
3 x beeps: Server connection successfully established. Now you can connect to the
App. This process can take about 5 minutes.
Note: If the 3x beeps are not heard, the Connect Box has not been able to establish
a connection to the server. Check for a stable Internet connection and possible secu-
rity settings on the WLAN router. In this case, start the Connect Box by briefly dis-
connecting it from the power supply and plugging it in again. The Connect Box
should now automatically connect to your WLAN and try to establish a connection to
the server.
6. After you have successfully connected to the server, you can connect to the sauna
via the App.
