The B.E.G. PD4N-ST KNX is a KNX presence detector with integrated bus coupler, designed for lighting and HVAC automation in connected buildings.
It features adjustable PIR detection, mixed light measurement and several operating modes: automatic, intelligent semi-automatic or occupancy-independent regulation. The detection area can be extended using master-slave mode.
The device allows control of one lighting group, one slave device output and three separate HVAC blocks. It also supports lighting scenes, soft start, locking functions, forced switch-off and manual operation via external KNX push buttons.
Configuration is carried out via ETS, with KNX Secure Ready support. Some functions can also be controlled remotely via IR adapter, B.E.G. smartphone app or optional IR remote control.
