VMBGP4PIRW - Glass control module with 4 touch keys and built-in motion and twilight sensor, white

The VMBGP4PIRW provides 4 touch buttons as well as motion, twilight and even absence detection. The built-in astronomical clock allows time dependent control. The module simultaneously detects movement for a movement sensor and light dependent movement for lighting control. If the controlled light shines into the PIR sensor, the sensor will continue detecting so you are never left in the dark (presence detection).


  • Only a qualified professional may carry out the installation in conformity with in force legislation and standards.

  • protocol manuals for developers

List of actions per module
Q. How to make a Velbus motion sensor switch the light?
A. A Velbus motion sensor (VMBPIRO, VMBPIRC, VMBPIRM, VMBGP4PIR) has to switch the light on during 3 minutes when motion is detected. How do I program this in Velbuslink? Read more ... (PDF)
Q. How can I make a Velbus motion sensor switch a relay at the second movement within 1 minute (to avoid false alarms)?
A. Read more... (PDF)
Q. Using a glass control module as code keypad
A. Velbus input modules can be used as simple code keypads by configuring the right set of actions. Read more...(PDF)
Q. Advanced configuration of a PIR motion sensor, light and ventilation in the toilet
A. The following functionality needs to be programmed:
- a Velbus PIR motion detector switches the light on in the toilet
- 2 minutes after the light goes on, the ventilation has to start
- 3 minutes after the light goes out, the ventilation has to stop
- if the light is off before the 2 minutes have passed, the ventilation has to stay off

Q. PIR sensor different dimming values before and after sunset
A. My PIR sensor switches a dimmed light circuit. When movement is detected, the light should be switched on at 70% during the day, and at 30% during the night. Read more ... (PDF)
