The current implementation only allows for the master valve to be turned off so many seconds AFTER the program has ended. I have some areas that have automatic drains after the master valve and need a pressure drop to be able to open.
I would like the ability to be able to close the master valve so many seconds BEFORE the zone valve is closed to allow a pressure drop to occur between the master valve and sprinkler heads.
This could be implemented as simply as allowing for the option of negative time (say up to -60sec) before the cycle ends to have the master valve close.
