ARCUS-EDS 30543362 SK30-TTHC-VOC Dark grey

<p/the product ARCUS-EDS 30543362, called SK30-TTHC-VOC, is a KNX sensor designed to measure and control indoor air parameters in domestic and commercial environments.

Key Features

This sensor integrates several measurement functions, including:

• Air temperature (sensors inside the device)
• Relative humidity (sensors inside the device)
• Concentration of volatile organic compounds (VOC) in ppm of CO2 equivalents
• External temperature through the connection of a PT1000 sensor

Calculations and Derived Values

Based on the data collected, the sensor also calculates:

• Absolute humidity
• Dew temperature
• Enthalpia (energy content of air)

Control functions

The SK30-TTHC-VOC offers several control functions for heating and cooling applications, including:

• Setpoint for comfort, standby, economy and protection
• Request for heating and cooling as additional signals
• Decentralized control for KNX thermal valves or actuators
• Decentralized ventilation control based on humidity and air quality
• Temperature detection of components to prevent condensation and structural damage

Binary Logic and Mathematical Functions

The device supports binary logic functions (AND, OR, NOT, XOR) and mathematical operations (addition, subtraction, multiplication) for 8-bit values, as well as the comparison function for conditional forwarding of events.

Technical Data

The main technical data of the sensor are:

• Temperature range: 0°C to +50°C (indoor), -50°C to +250°C (outdoor with PT1000)
• Temperature accuracy: ±0.3°C
• Temperature resolution: ±0.01°C
• Humidity range: 5% to 95% R.h.
• Humidity accuracy: ± 3% R.h. (20-80% at +20°C), otherwise ± 5% R.h.
• VOC measurement range: 450-2000 ppm of CO2 equivalents
• KNX Bus supply voltage: 21-32VDC
• Power consumption: about 240mW at 24VDC
• Binary inputs/outputs: 2

Applications

The SK30-TTHC-VOC sensor is ideal for:

• Detection and control of temperature and humidity in indoor environments
• VOC level detection
• Decentralized control of KNX thermal valves or actuators
• Decentralized ventilation control based on humidity and air quality
