The KNX S1-B2 230 V actuators with integrated facade control have a multifunctional output, button pairs and control LEDs. Either a drive with up/down control (blinds, awnings, roller shutters, windows) or two switchable devices (on/off for light and ventilation) can be connected to the multifunctional output. The connected drives and devices can be operated directly on the actuator and via connected manual buttons. The automatic function can be specified externally or internally. Internally, there are numerous options for blocking, locking (e.g. master-slave) and priority settings (e.g. manual-automatic). Scenes can be saved and called up via the bus (scene control with 16 scenes per drive). 2 binary inputs can be used either for direct operation (e.g. manual button) or as a bus button (or also for e.g. alarm messages). The desired behavior can be precisely defined by selecting the reaction times in standard, comfort or dead man mode.
