Hello!
I'd like to ask how to do a profile using PIR (Passive Infrared) Sensors (motion detection) to control the artificial lighting?
Many thanks,

PIR Sensors to control artificial lighting
Re: PIR Sensors to control artificial lighting
Hi,
This query was also sent in to Tech Support so here is the answer sent back (for other users who may have a similar query)
Since PIR sensors reduce the lighting load based on the space occupancy, and space occupancy is defined by the user, it is simply a case of modifying the lighting gain profile to reflect reduced loads as a function of PIR sensors. Alternatively a diversity factor can also be applied to the lighting gain inside the internal gains tab.
Within the UK Building Regulations Compliance methodology there is a menu item which allows occupancy sensing to be specified, but as above, all this achieves is applying a diversity factor to the lighting gain. If you use the UK Compliance modules this input is found at zone level, under the Building regs tab by selecting "NCM Lighting Data".
