Heating Actuators AKH

Description

The MDT Heating Actuator AKH has an integrated PI controller for heating and cooling each channel. To control the heating, the actuator receives the room temperature, for example, from an MDT push-button or presence detector with temperature sensor; it’s not necessary to use an external temperature controller. Up to 4 x 230 V AC (3 x 24 V AC) electrothermal actuators can be connected and controlled at each of the non-wearing outputs.

  • Installation Type: MDRC
  • Channels: 4-fold, 6-fold, 8-fold
  • Device width: 2SU, 3SU, 4SU

Product features

  • New generation with function extension
  • Each channel controls up to 4 electrothermic valve drives (230 VAC)
