Parameter settings

To optimize control performance, use the local HMI to enter parameter mode and adjust a number of control parameters. All control parameter settings are retained after power failure.

Proceed as follows to change the control parameters:

Or

Press and hold the + and - buttons simultaneously for more than 3 seconds.

Service level: Release the buttons, and within 2 seconds, press and hold + until Pxx is displayed.
Expert level: Release the buttons, and within 2 seconds, press and hold - until Pxx is displayed.

Press + or - (< or >) to access the desired parameter and the value of the selected parameter is displayed at the same time.

Press () to edit the value of the required parameter.

Press + or - to increase/decrease or select the value of the current parameter during editing.

Press () to confirm the new value or press () to cancel the change, and repeat steps 3 to 5 to change more parameters.

Press () to exit parameter setting mode.

Reload factory setting

  • Select parameter P89 and set it to 1.
  • The factory settings of the control parameters are reloaded.
    • “- - -” is displayed during reload.
