ARCUS-EDS 30543564 Neo-TTHC-VOC-AQB

The ARCUS-EDS 30543564 product, called Neo-TTHC-VOC-AQB, is a multifunctional KNX sensor designed for the control and measurement of indoor environmental parameters.

Key Features

• Air temperature measurement (sensor integrated in the body of the device) with the possibility of integration with an external temperature through a PT1000 sensor.
• Humidity measurement (sensor integrated in the device body).
• Measurement of the level of VOC (Volatile Organic Compounds) (sensor integrated in the body of the device).
• Calculation of values such as absolute humidity, dew temperature and energy content (enthalpy).
• Temperature measurement of components, floors or ceilings using an external PT1000 sensor terminal.

Control functions

• Temperature control for heating and cooling applications, which can be combined.
• Setting setpoint temperatures for Comfort, Standby, Economy and Protection.
• Decentralized control for KNX valves or thermal actuators.
• Decentralized ventilation control based on humidity and air quality.
• Component temperature detection and temperature control to prevent condensation and structural damage.
