Connections and wires Fig. 3: Wiring details Danfoss 80G435 OCTO C Electronic Thermostat 100 – 240 V AC ~ COMM Cable This distance has to be at least 5 cm in case the power supply is not double insulated 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.

Once discovered the best position with respect to the Antenna Signal Level, it is possible to decide if it is the case to protect the Side B (the one with the connectors) of the OCTO. To this aim, it can be adopted the same approach that the cooler manufacturer uses to protect the connector side of the electronic thermostat, hence a piece of plastic with an appropriate shape can be used.

In the same phase, also the OCTO device has to be installed.

Prosa mandatory settings This section is to highlight the fundamental importance of the STEP 7 listed in Section 6. The association between the equipment and the PR-OCTO can be done: • Using the mobile app • With the Alsense Portal • or other modalities previously agreed with Danfoss (contact via e-mail: support.prosa@danfoss.com).
