UP 258D53 KNX Presence Detector WIDE multi PIR Lux Temp RH CO2 Black 5WG1258-2DB53

The 5WG1258-2DB53 (UP 258D53) is the flagship WIDE multi presence detector, offering a comprehensive sensor suite in a single ceiling-mounted device. This advanced detector combines PIR presence/motion detection, brightness, temperature, relative humidity, and CO₂ concentration measurement — five critical environmental parameters for complete building automation.

Designed for indoor installation with 360° horizontal detection and coverage up to 64 m² for presence detection and 400 m² for motion detection, this device enables demand-controlled automation of lighting, heating, cooling, and ventilation systems. The integrated CO₂ controller supports demand-controlled ventilation strategies with 3-level thresholds or continuous control, while the humidity controller with dew point alarm ensures condensation protection.

The CO₂ controller directly drives fresh-air damper or ventilation system actuators via KNX, ensuring optimal air quality without over-ventilation. Combined with presence-triggered lighting and humidity-based condensation protection, a single device replaces multiple standalone sensors — significantly reducing installation costs and cabinet space requirements.
