Definizioni terminali:
- COMUNICAZIONE: Terminale comune del relè.
- NO: Normally Open terminal of the relay. When the relay is not working, NO is disconnected from COM.
- NC: Normally Closed terminal of the relay. When the relay is not working, NC is connected to COM.
- V+: 12V Positive input.
- V-: 12V Negative input.

6. Operating Modes & Pairing
The relay module supports several operating modes, which can be configured by pressing the learning button on the receiver module a specific number of times. Always clear previous pairings before setting a new mode.
Clearing Paired Remote Controls:
Press the learning button 8 times. The indicator LED will flash, confirming all previously paired remote controls have been cleared.
Setting Operating Modes:
After clearing, press the learning button the specified number of times for your desired mode, then press a button on your remote control to pair.
- Modalità momentanea: Press the learning button 1 time. Press and hold the remote button to turn ON, release to turn OFF.
- Modalità di commutazione: Press the learning button 2 times. Press the remote button once to turn ON, press again to turn OFF.
- Modalità bloccata: Press the learning button 3 times. (Requires a 2-button remote). Press button A to turn ON, press button B to turn OFF.
- Modalità di ritardo: Press the learning button 4, 5, 6, or 7 times for 5s, 10s, 15s, or 20s delay respectively. Press the remote button to turn ON, it will automatically turn OFF after the set delay.

7. Risoluzione Dei Problemi
- Il telecomando non risponde: Ensure the receiver module is powered correctly (12V DC). Check if the remote control is paired to the receiver. If not, follow the pairing instructions.
- Gamma limitata: Ensure the antenna on the receiver module is extended and not obstructed. Environmental factors like thick walls or other RF interference can reduce range.
- Modalità di funzionamento non corretta: If the relay operates unexpectedly, re-clear all paired remotes and re-pair them in the desired operating mode.
- Il LED non si accende: Verify the power supply connections to the receiver module. Check the LED itself for damage.
8. Informazioni sulla sicurezza
- Scollegare sempre l'alimentazione prima di effettuare qualsiasi cablaggio o manutenzione.
- Assicurarsi che tutti i collegamenti siano ben saldi per evitare cortocircuiti.
- Non esporre il modulo all'umidità o a temperature estreme.
- This device is intended for low-voltage DC applications. Do not connect to AC power unless specified.
