MDT AKK-04FC.03 KNX Fancoil Actuator, 4 Switching Outputs, 16A, 230VAC, 2 TE, 70µF, 10 EVG

Controlling fan coil units in KNX building automation often requires multiple actuators for fan speeds and valve control, leading to complex wiring and increased space in the distribution board. The MDT AKK-04FC.03 solves this by integrating four independent switching outputs in a compact 2 TE housing, specifically designed for fan coil applications in 2-pipe and 4-pipe systems.

Who is it for

This actuator is intended for electricians and system integrators who need a reliable, space-saving solution for controlling fan coil units in residential or commercial KNX installations. It is suitable for both new projects and retrofits where DIN rail space is limited.

Main features

• Four switching outputs, each rated 16A AC1 at 230VAC
• Supports 2-pipe and 4-pipe fan coil systems
• Three fan speeds controlled via three outputs, plus one output for valve control
• High capacitive load capability: 70µF per output
• Can switch up to 10 electronic ballasts (EVG) per output
• Manual operation via push buttons and status indication via LEDs
• Compact 2 TE (DIN module) width for DIN rail mounting
• Low bus power consumption: less than 0.3W
• Configurable with ETS software, firmware updateable
• Screw terminals for secure wiring
