The Voltic Contact Sensor PRO is the same model for door and window. It detects opening and closing via a magnetic sensor and allows the system to turn off HVAC when an open window is detected.

Sensor identification

The inner packaging label indicates the installation type:
  • P = Door (Puerta)
  • V = Window (Ventana)

Window sensor

Placement

  • Place the sensor on the window’s fixed frame.
  • Place the magnet on the moving sash.
  • The sensor’s triangle must face the magnet.
  • Distance between sensor and magnet: between 2 and 5 mm. On magnetic surfaces, keep a distance of 1 to 3 mm. Never exceed 5 mm.

Door sensor

Placement

  • Place the sensor on the door’s fixed frame.
  • Place the magnet on the moving leaf.
  • The sensor’s triangle must face the magnet.
  • Distance between sensor and magnet: between 2 and 5 mm. On magnetic surfaces, keep a distance of 1 to 3 mm. Never exceed 5 mm.

Mounting

1

Apply adhesive

Apply Sikaflex-118 Extreme Grab over the 3M adhesive base of the sensor and the magnet.
2

Press

Press the sensor and magnet firmly for 10 seconds against the installation surface.
3

Alternative with screws

If the surface does not accept adhesive or requires greater resistance, use screws to fix the bases.

Power supply

The sensor runs on 2 included AAA batteries. Open the compartment and verify polarity before closing it.

Common mistakes

If you place the magnet on the fixed frame and the sensor on the moving leaf, the device may not work correctly.
A distance greater than 5 mm between sensor and magnet prevents detection of the closed state.
The sensor must always go on the fixed part. Placing it on the moving leaf exposes the wiring to breakage from movement.
The sensor’s triangle must face the magnet. If they are not aligned, the magnetic contact will be erratic.
Without Sikaflex-118 Extreme Grab, the 3M adhesive may not withstand continuous use on irregular surfaces.
Keep the sensor away from the latch and hinges to avoid mechanical and magnetic interference.

Verification

The sensor’s green LED blinks when opening or closing the door or window. If it does not react:
  • Check that the batteries are properly placed and charged.
  • Check that the distance between sensor and magnet is correct.
  • Verify Zigbee network coverage in the area.
  • Sync the sensor on app.voltic.es if it does not appear on the platform.
