The PR-OCTO device is an IoT Enabler specifically designed for cooling applications like bottle coolers,
ice cream cabinets and other refrigeration type of equipment. This Enabler allows connectivity and
access to the Alsense™ Cloud solutions from Danfoss.
Electronic thermostats, in general, by monitoring the temperatures and states related to the
equipment, control the compressor and fan relays and generate warnings and alarms. By means of
a wired connection, PR-OCTO can obtain from the thermostats diagnostic and alarm data relating
to the equipment, or create new ones. Thanks to the presence of a modem and an M2M SIM on
board, PR-OCTO communicates with the Alsense™ monitoring platform through the mobile network,
transmitting the collected data. PR-OCTO also scans the mobile network and nearby WiFi HotSpots to
determine its position and transmit it to Alsense™.
If in Alsense™ the refrigeration system is located in a position other than that transmitted by PR-OCTO,
an alarm is notified on the monitoring platform. Authorized personnel can access Alsense™ to view
active alarms and decide if PR-OCTO has to lock the operation of the refrigeration system.
Danfoss guarantees a continuous after-sales maintenance of the PR-OCTO devices as they can be
updated remotely (FOTA) or on site via the mobile app.
