I have a 16 zone unit with 10 zones wired and in use. Is it possible/safe to set up schedules on the unused/unwired zones to shadow/beta test alternative schedules? When a zone is run, I imagine that the unit completes the circuit for that zone, but I don’t know if the unit also checks if current is flowing in that circuit and detects a short/open/unconnected condition.
I do it all the time. No issues…
Pro tip, set the time for your shadow schedules 1 minute after all your real schedule so they don’t accidentally postpone your real schedules
