the mobile app after the free year you don’t have to pay and can
use the sauna only manually, through the control panel. Payment is
made by credit card in the mobile app.

SIM is activated and the sauna will be connected to the network
within 30 minutes.
• Check whether all the functions of the mobile application are wor-
king properly and your commands actually reach the sauna. Com-
mands should be executed within 60 seconds. In case the functions
of the mobile application do not work, contact the manufacturer:
[email protected].
NB! In case the control console is not connected to the user account
in the mobile application, the sauna will not be connected with the
network.
