Hi have just fitted a new pcb to a carrier 30GG 045-911E chiller after it blew but on firing the system back up the word COnF appears in the display for the pro dialog plus controller. In the manual it says that the basic board needs configuring and that this can only be carried out by a carrier service engineer.
Just wondering if anyone knows how to do this as don't really want to spend more money on getting carrier out as the pcb cost a small fourtune.
Thanks for any help
