It is unfortunatly not possible to change  in which ordre the watering will act.

for exemple I need to water zone 5 after zone 7 because zone 7 is at a higher level than the electro valve and remaining water pressure, after watering is stopped,  is to strong and prevents the valve to close . by watering supplemantary  zone 5 which is lower the pressure diminishes ans the valve of zone 7 closes..
