VMBPIROB - Outdoor motion, twilight and temperature sensor, black

The VMBPIRO is much more than an outdoor motion detector. This adapted Theben sensor allows you to simultaneously use motion and light sensitivity as well as temperature measurement. The built-in astronomical clock allows the VMBPIRO to operate time-dependently. The module also simultaneously detects motion for a passage signal or light dependent movement for lighting control.


  • 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. How can I disable and enable push buttons and sensor channels at certain times?
A. A light needs to be switched by a PIR sensor from 8:00 until 22:00, and by a push button from 22:00 until 8:00. How do I program this in Velbuslink? Read more... (PDF)
Q. How can I make a motion detector set a light to a certain dim value during a certain time?
A. A Velbus motion sensor needs to turn a light on at a certain dim value (eg. 50%) during a certain time (eg. 1 minute).
This can be done as follows:
- in the configuration of the Velbus motion sensor module, set the timeout of the motion output to 1s
- create an action "Set to percentage" with the motion output channel as initiator and the dimmer channel as subject. Set the dim percentage parameter (in our example 50%). This action has also a "duration" parameter. Set this to the desired on time (in our example 1 minute)
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)
