IoT Enabler for remote control and tracking of refrigeration equipment
The PR-OCTO Lean 2G Y8 0T (code no.
300B5070) device is an IoT Enabler specically
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 notied 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.

Compatibility
The PR-OCTO device gives the possibility to execute the lock command and to collect the diagnostic information
only in conjunction with an electronic thermostat.
The current version of the PR-OCTO includes the compatibility with the thermostats listed in Table 2.
Table 2: Compatible electronic thermostats
Connections and wires
Figure 3: Connection to an electronic controller
The PR-OCTO requires two connections, one for the power supply, the other with the electronic thermostat.
The power supply must be shared with the electronic thermostat: the PR-OCTO must be powered on only when the
thermostat is also powered on. If the PR-OCTO is powered on when the thermostat is o, a “Controller
communication failure” alarm is raised after 60 minutes.
NOTE:
Neither the cables nor the connectors are included in the PR-OCTO package.
For the POWER SUPPLY connector of the PR-OCTO, either two standard fast-on connectors or one connector with
screw terminal can be used. In Table 3, illustrates the Lumberg 3611 02 K1, an easy plug connector with lift clamp
and protection against misplacing and fast assembling. Neither the easy plug connector nor the standard fast-on
connectors are included in the PR-OCTO package.
NOTE:
If the power supply cable is not double insulated, it must be physically separated from the COMM cable.
