3.4 Initial set-up with WLAN operation
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 plugging it in again.
After it is switched on, the Connect Box searches for all available WLAN connections. 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 processes 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 inhouse WLAN. You may not have enough WLAN reception or a wrong WLAN password. You may need to move the Connect Box to another location. Please check
both and start again at step 1.

– Repair work must be carried out only by qualified personnel, unless oth-
erwise specified.
– Before starting work make sure there is sufficient space for the installa-
tion.
– Pay attention to order and cleanliness at the place of installation. Loose
components and tools lying around or on top of each other are safety
hazards.
– If parts are to be replaced: Ensure correct installation of spare parts. In-
stall all fastening elements properly again. Only use original spare parts.
– Ensure that all covers are properly installed before restarting.
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. This can lead to steady state of
the consumer. Switch off the automatic circuit breaker in the junction box.
Contact customer service.
