The code Klove gave is the correct one if you changed the micro board or expansion module you will need the set the motor protection info. back up as you are already experiencing problems due to that.

Installing a new board in chiller. I tried to program the 21 different menus and can find only 14. The chiller will run a comp for about a min. and then go off on over amp because one of the menus I cant find is motor current setting. Do I need to set a dip switch to get to these additional 7 menus? I have used the password given in the IOM (7396) and also the York password (9675). Still cant find.
