When connecting an RC-2000 to an OPII controller, the manual says to run a yellow wire from the RC-2000 to the positive terminal on zone 16 of the OPII. The manual doesn't say how to define that zone in the OPII. Should I leave the zone type on zone 16 set to auxiliary, or change it to something else?
