Here below you will find the meaning of the parameters and the definition of the valve:

  • D= disable (valve disabled)
  • O= open (Valve opened)
  • X= close (valve closed)
  • I= intermittent (valve intermittent)
  • P= pulsing (pulsing valve)
  • N= negative pulsing (negative pulsing valve). This has been inserted as some compressors on the market have this valve always active, while it start pulsing when disabled.
