If the firmware update does not resolve the Random Freezing of the Screen, please take the following steps to format file system
(A) SAVE EXISTING CONFIGURATION SETTINGS (set points/equipment settings/stages).
To save your configuration you would do the following:
Insert USB stick into controller
Press OK-> SystemSetup->SaveRestore->SaveRestoreConfig->SaveConfig (button 1)
A window will pop up with options - you want to save to USB-> then enter file name and press OK
NOTE: follow same steps when restoring configuration, but instead of saving you would be restoring (button 2)
(B) FORMAT FILE SYSTEM/CLEAR HISTORY
OK-> System Setup-> Advance-> clear all data (button 3) -> 1st Clear History (button 1) 2nd format file system (button 2)
(C) RE – INSTALL YOUR SAVED CONFIGURATION FILE
If this does not resolve the issue
(D) RE-PROGRAM CONTROLLER FROM SCRATCH
You want to input your settings by hand, not using a saved configuration.
