Use
- Temperature control of the return water to the boiler or other energy source.
- Constant temperature control of the inlet to the heating or cooling system.
Compact constant temperature controllers ACD20
ACD compact controllers are designed to control a constant temperature in the pipeline. The controller is set using a keypad and a graphic display, which is also used to show measured temperatures and other data. An integrated motor drive is used to control the mixing valve. The controller shall be connected to the power supply by means of a prewired cable with plug.
