4-way comfort push button sensor B.IQ made of stainless steel. 4-way comfort push button sensor B.IQ with dismantling protection, with one operating and eight status LEDs. Flush-mounted installation. The 4-way comfort push button sensor is an instabus user module. It is used to plug onto a bus coupler. Dismantling protection is provided by screwing the push button sensor to the bus coupler. The data exchange between the push button sensor and the bus coupler takes place via the user interface (AST). Each button press on the 4-way comfort push button sensor causes the bus coupler to generate a telegram and send it to the bus. The telegram format depends on the parameterization of the application. Depending on the parameterization selected, switching, dimming, blind and value transmitter functions can be combined as desired. Application properties: Button functions (buttons, switching), switching in toggle mode, dimming with one/two-surface operation, blind control with one/two-surface operation, value transmitter/light scene extension with 1-byte value transmitter function, light scene recall with/without memory function, brightness value transmitter, temperature value transmitter, 2-byte value transmitter, cyclical sending, control function, forced operation. Other functions: Two operating levels, second operating level with selectable reduced functionality, switching of operating levels manually via key code or via object.
