Software
Per utilizzare l’input COUNT IN è necessario seguire la descrizione riportata di seguito.
.
For use the input COUNT IN you must follow the description below.
- Cliccate rispettando la sequenza sulle icone numerate 1, 2 e 3 evidenziate sotto.
Click in sequence on the icons numbered 1, 2 and 3 highlighted below.
- Una volta che avete selezionato AZIONI, premere su Aggiungi Azione e inserite le azioni che volete che svolga l’ingresso COUNT IN.
Nell’esempio riportato si nota che se la frequenza in ingresso è superiore a 2Hz il dispositivo metterà in ON (OUT 1) e se invece la frequenza sarò minore di 1Hz il dispositivo metterà in OFF (OUT 1).
.
Once you have selected ACTION, press Add Actions and enter the actions you want the COUNT IN input to perform.
In the example shown, you can see that if the input frequency is higher than 2Hz the device will turn ON (OUT 1) and if the frequency is lower than 1Hz the device will turn OFF (OUT 1).
Sequenza su OFF ritardato se Freq. è minore di 1Hz
.
Delayed OFF sequence if Freq. is less than 1Hz
Questa sequenza sotto è importante e dovrà essere la seguente:
SPENTO ………………………………………… OFF
SPENTO + TOGGLE di 2 sec ……………. Dly di 2sec e ON di nuovo
SPENTO + TOGGLE di 300 sec ………… Dly di 300sec e ora OFF definitivo
300 secondi sono 5 minuti ovvero: 300/60
This sequence below is important and must be as follows:
OFF ………………………………………… OFF
OFF + TOGGLE for 2 seconds ……………. Dly for 2 seconds and ON again
OFF + TOGGLE for 300 seconds ………… Dly for 300 seconds and now OFF permanently
300 seconds is 5 minutes, or: 300/60
Ecco come compare l’icona dello Shelly UNI PLUS quando Freq.>2 Hz (OUT 1 è ON)
.
This is how the Shelly UNI PLUS icon looks when Freq.>2 Hz (OUT 1 is ON)
Ecco come compare l’icona dello Shelly UNI PLUS quando Freq.<1 Hz (OUT 1 stà per andare OFF è c’è il delay in corso prima dello spegnimento)
.
This is how the Shelly UNI PLUS icon appears when Freq.<1 Hz (OUT 1 is about to go OFF and there is a delay in progress before switching off)
Ecco come compare l’icona dello Shelly UNI PLUS quando Freq.<1 Hz (OUT 1 è ora in OFF)
.
This is how the Shelly UNI PLUS icon looks when Freq.<1 Hz (OUT 1 is now OFF)
