ARCUS-EDS 30531372 SK30-THC-PB Dark Grey

The ARCUS-EDS 30531372 product, called SK30-THC-PB, is a temperature and humidity sensor designed to be integrated into KNX systems. This device is ideal for measuring and controlling indoor air parameters.

Key Features

• Air temperature measurement (with internal sensor) and possibility to weigh the outside temperature.
• Humidity measurement (with internal sensor) and calculation of absolute humidity, dew temperature and energy content (enthalpy) values.
• Control functions for 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 KNX objects.
• Storage of minimum and maximum temperatures.
• Alarm for overheating and freezing.
• Limits for temperature and humidity.
• Request for heating and cooling as additional signals.

Logical and Mathematical Functionality

• “AND, OR, NOT, XOR” logical functions for binary values.
• Mathematical functions “+, -, *” for 8-bit values.
• “=” function for conditional forwarding of events.

Applications

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