Description : Stepper electronic expansion valve driver with integrated display - XEV22D
Having a buttons and a display with measurement units, the XEV22D supplies a complete solution for superheat control. The display with icons permits visualization of: the superheat value, the opening time percentage and the probe values. Programming of the driver can be local, using the XEV22D's own keyboard.
