Et17 Number of additional steps to achieve complete closure. When a closing
request is received, the valve starts from the current number of steps and
moves to 0, then closes for the set number of steps
0 250
Et18 Number of return steps in opening mode after the valve has been closed
completely. These decompress any closing spring inside the valve or to
prevent sealing the circuit
0 250
Et19 Maximum number of adjusting steps of the valve Et20 8000
Et20 Minimum number of adjusting steps of the valve 0 Et19
Et21 Maximum current value per phase of the stepper motor 0 100 mA x10 mA
Et22 Current stand-by value 0 100 mA x10 mA
Et23 Maximum number of steps per second of the valve 0 600 Hz
Et24 Indicates the number of steps the valve has to move before compressor
start-up.
