Standard VISI Cooler
Preferred area:
Inside, On top
Best position:
Inside the canopy
Preferred area:
Back, outside,
next to the top
In this case, the OCTO
has to be protected
by an additional cover
in order to avoid any
possible electric shock.
The OCTO has to be
unaccessible by any
person.
Lean Cooler
On standard visi coolers the best area is inside the canopy, since the canopy usually does not have
metal plates that could decrease the mobile network signal.
On lean cooler, since the lack of the canopy and the presence of metallic plates all around the cooler,
the OCTO can only be installed outside the cooler, in the back area, next to the top.
Note:
In case of installation on the back side of the cooler, the OCTO has to be protected with an
additional box to protect people from electric shock.
Mobile application
(recommended)
Danfoss has developed a mobile application for Android and IoS that can be used also for check the
best position where to install the OCTO in the cooler. This is the suggested way to check the best
position to install the PR-OCTO into the cooler.

PC application
Danfoss has developed a specific PC software to help discovering the right position of the OCTO in the
cooler. To exploit such software, follow these steps:
Step 1: Download the VBCTKSignalTester application from this URL: http://area.riservata.it/
vbctksignaltester-1.0.0-setup-x86_32.exe
Step 2: Install the VBCTKSignalTester application in a Windows PC.
Step 3: Connect the 'Test Cable' (see Fig. 5) to the PC and to the OCTO.
Step 4: Power on the OCTO (see Section 4 for the power supply cable).
Step 5: Run VBCTKSignalTester and select the appropriate Serial COM port to which the 'Test Cable' is
connected, as shown in Fig. 6a.
Step 6: If the program shows “No Connection” as in Fig. 6b, try to change the COM port listed in the
combo or check the cable connection.
Step 7: When the system is finally connected to the device, it starts to display the Antenna Signal Level
of the OCTO’s internal antenna. Such level could be low (like in Fig. 6e), medium intensity (like
in Fig. 6f) or almost the best signal level (like in Fig. 6d).
Step 8: Try to change the position of the OCTO in the cooler in order to discover the highest possible
Antenna Signal Level.
Step 9: Power off the OCTO and disconnect the PC 'test cable'.

5. Choosing the position in
the cooler
The most important requirement for the OCTO installation is to find the location inside the cooler
where the mobile network signal is stronger and the device protected. The diagram below suggests
the recommended positions for coolers:
