I am using my sa doser as a slave to my p4 unit. Is there a way to still use the level sensor port off the doser? I’ve tried, with a plugged in float switch, to see which sensor # (1-16) it was assigned to and it doesn’t appear to be active. Am I missing something or is the level sensor only available when the doser is in stand alone mode.
