Compatibility
ETS Colibri is a driver-controlled stepper valve — it does not operate stand-alone. Drive with a Danfoss EKE, EKF, MCX or AK-XM 208C driver providing the stepper phase current. M12 4-pin connection cable (034G70xx/71xx) ordered separately. Verify model capacity class, inlet/outlet ODF size and refrigerant before ordering.
