MDT AKI-0416.04 8-channel KNX heating actuator AKH-0800.03

8-channel KNX heating actuator AKH-0800.03 – MDT – 4251916130145: 8-fold heating actuator, 4SU MDRC, 24-230VAC. Heating actuator for controlling electrothermal valve drives. LED indicator for each channel. New generation with extended functionality. Each channel controls up to 4 electrothermal valve drives (230VAC). Free assignment of outputs to the controller channel. Controllable with 1Bit (Switching/PWM) / 1Byte actuation variable or direct control with temperature value via KNX bus. Integrated PI temperature controller (heating and cooling). Comfort, night and antifreeze protection. Summer/winter operation. Absolute object of 1Bit +/-, 1Byte or 2Byte to set the given value. The nominal values are stored in the event of a bus voltage failure. Emergency operation in case of failure of the cyclic actuation variable. Overload protection with fault message object (230VAC). Detection of mains voltage failure with fault message object (230VAC). Objects for heating request and cyclic movement of the valves. Full scene functions. Compatible with many views. Minimum delivery temperature. Diagnostics for each channel with 14Byte plain text object. Quick application download (long frame support for ETS5).
