Description : Stepper electronic expansion valve driver - XEV21D
The XEV11D controller is equipped with simple LEDs to signal the working state, it does not have a full display but can be easily programmed using the KB1-PRG hand held programming keyboard. The keyboard is only used during the programming phase; during the normal operation XEV11D works on it's own.
