I have an ESPMe and I would like one station to water every day and the others to water tue and sun. I talked to a guy at Rainbird and he said setup a B program. Will I have to switch between the programs or will they both be active as long as the times don't conflict?
All programs operate. No having to switch back and forth. If you do schedule a conflict, the controller has a protocol for sorting things out. (Read your owners manual)
