must be connected as per final configuration.

ATTENTION:
We recommend you check the control unit before starting the device.
The default parameters set by TECSYSTEM might not suit your requirements.
Programming the device is the end user’s responsibility: the set alarm thresholds and the enabled functions
described in this manual must be checked (by a specialized technician) referring them to the application and
system characteristics on which the control unit is installed.
