InformationThe bus coupler 3 connects a KNX system to a KNX application module (e.g. a push button sensor 3).
The combination of bus coupler 3 and application module represents a functional unit. In the ETS project, this unit is configured in the form of the application program of the application module.
In addition, a remote temperature sensor can be connected to the bus coupler 3 with external sensor 2009 00. This enables a room temperature controller to record the temperature at an additional measuring point.
Temperature range: -5 °C to +45 °C
