Operating on manual (all stations are ticked with “Activate Master”), I get stations 1 to 4 to work ok. Stations 5 to 10 DON’T althouigh you can hear the station soleniods openning with no water flow, so the master valve is not operating electrically.
Do you mean you can hear the master station solenoid open, or do you mean you can hear station 5 to 10 solenoid open?
Because you can open each station manually, the only thing I can think of is the ‘activate master’ flag is not turned on for stations 5 to 10. But you are pretty sure those flags are turned on already. I will check firmware 2.0.0 and see if I can reproduce this problem.
