Presentation

    ACD compact controllers are built into the actuator housing. The temperature sensors and connection cables are pre-wired in the controller, therefore the installation is quick and flawless. They are distinguished by compact design and ease of use. The controllers feature a colour graphic display.

 

Application ACD20

  • Boiler return temperature or any other energy source temperature control
  • Heating or cooling system supply temperature control.

 

Advantage ACD20

  • 3 preset hydraulic schemes.
  • Directly integrated sensor.
  • Two sensor option.
  • Adjustable temperature control.
  • Simple user interface.
  • Direct installation onto 20 different mixing valves.
  • The possibility to configure the mixing valve opening direction.
  • Innovative connector system for connecting sensors.
