Information
Theben HU 1 S RF KNX
Art. No.: 4941641
Application
The HU 1 S RF KNX is a 1-channel RF flush-mounted heating actuator designed for silent control of thermal actuators (230 V AC) in KNX systems. It includes an integrated temperature controller, supporting both heating and cooling modes. Communication is wireless via KNX RF with support for KNX Data Secure for encrypted data exchange.
Features
- 1-channel RF flush-mounted actuator for heating/cooling
- Silent operation of thermal actuators (230 V AC)
- Integrated temperature controller for heating and cooling
- Valve protection function for long-term reliability
- 2 binary inputs for potential-free contacts such as pushbuttons, switches, or temperature sensors
- Factory-assigned input-to-output mapping allows function testing before programming
- Secure commissioning and communication via KNX Data Secure
- Compact housing for easy, space-saving flush installation
- Integrated temperature monitoring for safe operation under overload conditions
