If There is an active running zone already that zone will be put into the pending list and will run after the run immediate time or volume elapeses. If there is not an active running zone the zone and recipe selected will be started immediately.

The Add to Pending List button will only be enabled if there is an active running zone at the time when the system is paused. This button will not run immediately, but add the user selected zone and recipe to the pending list. The user selection will then be run once the current active running zone is complete.
