The 5WG1258-2DB12 (UP 258D12) is a KNX-bus-powered ceiling-mounted presence and motion detector with integrated brightness sensor, designed for intelligent lighting control, HVAC occupancy management, and building automation in commercial offices, conference rooms, classrooms, and open-plan workspaces.
Communicating natively over the KNX/EIB bus, it requires no separate power supply — drawing approximately 10 mA directly from the KNX bus voltage (DC 24 V SELV). The PIR sensor provides 360-degree horizontal detection with three independent output channels (motion detector, presence detector, HVAC detector), each independently configurable with overshoot time, dead time, and telegram logic via ETS software.
The integrated brightness sensor (contrast measurement, 20–1000 lux) enables 2-level switching light control based on ambient daylight. A built-in IR receiver supports control via the S 255/11 IR remote control. Compatible with Desigo room automation systems via KNX PL-Link and with standard KNX S-mode BMS systems via ETS.

The 5WG1258-2DB12 is specified in commercial KNX building automation projects requiring integrated occupancy detection and daylight-linked lighting control from a single ceiling-mounted device.
In open-plan offices, the 360-degree detection coverage eliminates the multiple PIR sensors typically required for zone coverage, while the brightness sensor ensures artificial lighting is only activated when daylight falls below the configured threshold — directly reducing lighting energy consumption.
The HVAC detector output channel enables automatic switch-over between energy-saving and comfort mode in KNX-controlled HVAC systems (fan coil units, VAV boxes, heat pumps) when occupancy is detected or the space becomes vacant.
In conference rooms, the presence detector (with configurable overshoot time) prevents premature HVAC setback during quiet meetings where movement is minimal. The IR remote control compatibility allows facilities managers to adjust detection sensitivity and lighting setpoints without a laptop during routine maintenance visits.
