  • Associated product(s)
Implementation of a LOGO! 8 control function for a heater and an independent fan control. The fan control is achieved via the connection to a CO2 and air humidity sensor into a KNX system via the LOGO! CMK2000 communication module.

With the integrated functions like astro timer, yearly and weekly timer, many automation tasks can be solved quickly and easily with LOGO! 8. The LOGO! text display unit (TDE) and the integrated LOGO! 8 web server offer additional options for control and monitoring.

The communication module CMK2000 from Siemens provides a solution for communication in building automation with LOGO! 8. The communication module enables communication with any KNX devices via the KNX building system bus.

The application example offers a complete control function for the LOGO! 8 and shows you how to implement it into a KNX system via the CMK2000.
