Arcus SK30-THC-CO2-R KNX Sensor for Flush Mounting – White or Anthracite

The SK30-THC-CO2-R by Arcus-EDS is a versatile KNX sensor for flush-mounted wall installation. It measures and controls temperature, relative humidity, and CO₂ levels in indoor environments. With a compact design that fits standard 55 mm frames, this sensor is ideal for modern building automation and HVAC systems in KNX environments.

Available Variants:

White – Article number: 30532351 | EAN: 642125989411
Antracite – Article number: 30532352 | EAN: 642125989442

Applications:

Measurement and control of indoor temperature, humidity, and CO₂
Decentralized control of KNX valves and thermal actuators
Automatic ventilation control based on air quality and humidity
Evaluation of external switches and push buttons for control functions

Features and Functions:

Integrated sensors for temperature, relative humidity, and CO₂
Calculated values: absolute humidity, dew point, and enthalpy
Control functions for heating and cooling (can be combined)
Setpoint temperatures for Comfort, Standby, Economy, and Protection via KNX
Manual setpoint adjustment via integrated rotary controller
Storage of minimum and maximum temperatures
Heat and frost alarms with KNX notifications
Configurable limits for temperature, humidity, and CO₂
Fan control via humidity/CO₂ thresholds and external inputs
Dew point detection with regulation to prevent condensation
Controller output: 0–100% or PWM (programmable) for thermal actuators
Valve rinsing function
Four logic blocks for linking internal and external signals
Two floating binary inputs/outputs
Status indication via LED display
