2. Device positioning
The Minion (beacon) should be placed near the
entrance of the cold room, on the roof of the cold
room in the center of the door, or on one of the ver-
tical sides of the door frame 10-15 cm from it .
The Minion transmits this information that the
Freeze device will read in real time and then trans-
mit to the central monitoring system.
To ensure the correct functioning of the solution
and correct positioning outside the cold room, we
use a signal detector that makes use of the BLE
Scanner application (downloadable in the App Sto-
re or Google Play) by placing it outside the cold
room with the Identication code for the Minion.
In addition to the Minion device code (for example
003BBB9), the application also reports the signal’s
power level (eg Fig. 3: -65). The further you move
away from the cold store, the more the power value
decreases. It is advisable to keep this value above
-70 (eg -70, -68, -60 ...).

Therefore, the ideal place to install the Freeze must respect these two conditions:
1. Visible Minion code in the application
2. Signal level above -70
As an additional verication of the correct connection between Freeze (master) and Minion (beacon), the
Freeze is equipped with an internal button (Fig. 4).
Once the Freeze is positioned with the above criteria, open the device and press the button indicated in
Fig. 4, within 20 ”, the green LED on the master lights, indicating the start of the test.
