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. | |
Press + or - (< or >) to access the desired parameter and the value of the selected parameter is displayed at the same time. | |
Press | |
Press + or - to increase/decrease or select the value of the current parameter during editing. | |
