STATUS LEDS
The two LEDs L1 and L2 (on the right of the "Pair" push-button) indicate the wireless state of the sensor.
They activate after the system is switched on and deactivate automatically after approx. 30 minutes.
If required, the LEDs can be reactivated manually using the "Pair" push-button.
TELEGRAM LED
The LED (on the left of DIP switch A) flashes to indicate that Modbus communication is active.
If there is a fault in the Modbus cables, the LED lights up red steadily.
"PAIR" PUSH-BUTTON
Different functions are assigned to the "Pair" push-button.
Briefly pressing the button (tap) activates the status LEDs for approx. 30 minutes.
A long press of the button (≥ 10 seconds) activates Pairing.
Deactivation takes place automatically when you exit the Pairing mode on the master gateway.
A long press of the button (approx. 3 seconds) activates Bluetooth. The status LED L2 flashes green.
The unit remains visible for approx. 60 seconds and can be detected by the Lumenradio W-Modbus app.
The connection remains active until you press "Disconnect" in the app or activate Pairing mode on the unit.
