It does NOT default settings. Only clears FATL errors. I wish I knew off the top of my head how to adjust but I don't. I'm sure I can find out but I'm pretty busy this weekend.Keep in mind that if that Error happens again and its on the same floor put another wrap on the spirator on that door. It will cause the hall door to close a little faster and sometimes eliminates the timing issue that causes a FATL 94.
