AKU-B2UP.03 KNX Universal Actuator UP | 2-fold, 4 inputs

The AKU-B2UP.03 KNX Universal Actuator is a versatile and advanced combi-actuator for flush-mounted installations, ideal for use in KNX-based building automation systems. This actuator can function as a 2-fold switch actuator, 1-fold shutter actuator, or heating controller, making it a perfect solution for automating lighting, shading, and HVAC systems. With 4 potential-free binary inputs, conventional switches, shutter controls, and window contacts can be directly connected, providing comprehensive and flexible automation options.

Main features:

• Combi-actuator for use as a 2-fold switch actuator, 1-fold shutter actuator, or heating controller, with a switching capacity of 10 A per channel.
• Heating control via pulse width modulation (PWM) from 0-100% for precise and efficient temperature adjustment.
• Advanced shading control with automatic slat adjustment based on sun position calculation for optimal comfort and energy efficiency.
• Practical ventilation function for controlling windows in open or tilt position, with integrated window contact monitoring.
• Extensive time functions, including switch-on and switch-off delays, as well as staircase lighting functions.
• Status feedback per channel (active/passive) and logical linking of binary data.
• 8 programmable scenes per channel and central switching functions with lock options.
• Adjustable travel, pause at direction change, and step time for shutters and blinds.
• 1-bit automatic function for shading and 8-bit positioning for precise control.
• Configurable behavior in case of bus voltage failure or recovery.

Functions of the binary inputs:

• Connection for conventional switches, shutter controls, or window/auxiliary contacts.
• Integrated evaluation of window contacts for automatic ventilation and shading control.
• Configurable transmission behavior of up/down objects for control via internal contacts or the KNX bus.
• Support for controlling shutters and blinds with 1- and 2-button operation.
• Use of the binary inputs as a universal interface for various automation solutions.

Technical specifications:
