ETS Colibri is a driver-controlled stepper valve — it does not operate stand-alone. Drive with a Danfoss EKE 1A/1B/1C/1P or MCX 061V/152V controller (or a third-party driver providing 800 mA peak / 600 mA RMS per phase). M12 4-pin connection cable (034G70xx/71xx) ordered separately. Verify model capacity class, inlet/outlet ODF size and refrigerant before ordering.
