MDT AKK-03UP.03 KNX Switch Actuator with Fan-Coil Function, 3-fold, Flush-Mounted

The MDT AKK-03UP.03 is a compact KNX switch actuator with 3 channels and an integrated fan-coil function for controlling fans with three speeds and fan coil units. This device is suitable for both 2-pipe and 4-pipe systems, allowing manual and automatic control of fans and convectors. The outputs are interlocked through software to ensure efficient and safe operation.

Product Features

• 3-channel switch actuator with fan-coil function.
• Outputs interlocked via software control.
• Direct control by three 1-bit objects or a single 1-bit object (+/-).
• Automatic control by 1-byte control value (0-100%).
• Suitable for 2-pipe and 4-pipe systems.
• Output objects to control valves for heating/cooling.
• Day/Night function to limit fan speed at night.
• Emergency operation if the control variable fails.
• Switch actuator mode with time functions (switch-on/switch-off delay).
• Staircase lighting function with adjustable warning time.
• Status feedback for each channel (active/passive).
• Logical linking of binary data, 8 scenes per channel.
• Central switching functions and lockout functions for forced operation.
• Adjustable behavior in case of bus voltage return.
• Quick application download via ETS (long frame support from ETS 5).
• Flush-mounted installation in an electrical box.
• Manufactured in Germany, ISO 9001 certified.
• 3 years warranty.
