ARCUS-EDS 30512372 SK30-TC-CO2-PB Dark grey

The ARCUS-EDS 30512372 product, called SK30-TC-CO2-PB, is a KNX sensor designed for measuring and controlling indoor air parameters, particularly suitable for heating and cooling applications.

Key Features

This device integrates sensors for measuring the air temperature and the level of CO2 inside the building.

Measurement of Parameters

• Air temperature measurement (sensor integrated in the device body).
• Measurement of the CO2 level (sensor integrated in the body of the device).

Control functions

• Control of heating and cooling applications (can be combined).
• Setting setpoint temperatures for Comfort, Standby, Economy and Protection, selectable through KNX HVAC objects.
• Change the setpoint using front buttons and/or objects.
• Storage of minimum and maximum temperatures.
• Alarm for overheating and freezing.
• Limits for temperature and CO2 level.
• Fan control based on CO2 limits and external inputs.

Advanced Control Features

• Adaptation for setpoint and maximum temperatures.
• 0... 100% controller output or programmable PWM for thermal actuators.
• Valve flushing function.
• Second temperature controller as an auxiliary controller.

Interface and Input/Output

• Two front buttons to change the operating state (comfort/standby) and increase/decrease the setpoint temperature in several steps.
• Two binary inputs/outputs (floating), configurable as outputs (LED/Beeper).
• Light control as a switch/button with short, long, double and combined press functions.
• Dimmer control.
• Curtain and blind control.
• Programmable encoder.
• Temperature adjustment.

Logic and Signals

• Four logical blocks for the logical connection between internal and external signals.
• 10 associated logical inputs/outputs.
• Additional signals for heating and cooling requests.
• “AND, OR, NOT, XOR” logical functions for binary logic.
• “+ - *” functions for 8-bit values.
• “=” function for conditional forwarding of events.

Applications

• Detection and control of room temperature.
• Detection of the CO2 level.
• Decentralized control for stable KNX valves or thermal actuators.
• Decentralized ventilation control based on air quality.
• Evaluation of external switches and buttons for switching functions.
