Description

The Arcus-EDS SK20-THC-VOC-2B (article number 30533261) is an advanced KNX sensor designed to measure and control indoor air quality. This compact device integrates temperature, relative humidity, and VOC (volatile organic compounds) sensing and is ideal for smart building HVAC applications. Thanks to its integrated control unit, the device can independently manage climate functions via the KNX bus.

Important Note

This device contains built-in sensors and does not require any external power supply beyond the KNX bus. Compatible with ETS version 4 and above. Optimized for accurate climate control in residential and commercial buildings.

Applications

  • Building automation
  • HVAC control (heating, ventilation, cooling)
  • Indoor air quality monitoring (IAQ)
  • Offices, homes, schools, hospitals

Functions

  • Temperature measurement (internal + weighted with external)
  • Relative humidity
  • VOC level (air quality)
  • Calculation of absolute humidity, dew point and enthalpy
  • Control algorithms for heating and cooling (comfort, standby, economy, frost protection)
  • Storage of min/max values
  • Heat and frost alarms
  • Settable limits for temperature and humidity
  • Dew point detection and regulation in case of condensation risk
  • Control output 0–100% or PWM for thermal actuators
  • Fan control based on humidity limits or external inputs
  • 2 binary inputs for external contacts
  • 4 logic blocks for internal/external signal processing
