I'm swapping out my 522 for a new unit this afternoon and need a bit of help. My current unit is set up in dual mode. I recall the installer and I discussing this and deciding dual would be best for my purposes, but I can't remember why.
Can someone give me a quick rundown of single vs. dual mode. What are the advantages of each?
Thanks.
