5.3 Bluetooth fjernbetjening

Use the included Bluetooth remote for local control:

• Press buttons 1 or 2 to control the respective relays.
• "ALL ON" and "ALL OFF" buttons control both relays simultaneously.

6. Driftsformer

The module supports two main operating modes, configurable via the eWelink app:

• Skift tilstand: Each press of the button (app, voice, or remote) will switch the relay state (ON to OFF, or OFF to ON). This is suitable for lights or devices that need to stay on until manually turned off.
• Inching Mode (Momentary): The relay will turn ON for a set duration (e.g., 0.5 seconds) after a button press, then automatically turn OFF. This is ideal for momentary actions like garage door openers or electric locks. The duration can be configured in the eWelink app.

Image 6.1: The module can be configured to act as a momentary switch (push button) or a toggle switch (rocker switch).

7. Ledningsdiagrammer

Vigtig: Sørg for, at strømmen er afbrudt, før du udfører nogen form for ledningsføring. Hvis du er usikker på den elektriske ledningsføring, skal du kontakte en kvalificeret elektriker.
