2.5.1 Remove the Circuit board
Now the printed circuit board is tilted out of the front cover by pulling at the edge of the
semicircular cavity.
2.5.2 Configuration
The configuration of the OMS in house /humidity and temperature sensors can be done via DIP
switch. The functions of the DIP switch are shown in a table below the battery at the PCB
(between the battery holders). Before changing a configuration, the batteries should be
removed. Then the configuration can be customized via the DIP switches. After that the
batteries can be inserted again. The changes are applied with transmission of the next telegram
or with the restart of the sensor.
Between taking out the batteries and re-insert should be at least 30 seconds to secure
that the device has done a reboot safely. Please contact us by email to
to ask for the key if you want to use the encryption..
