@PJB, looks like this might be your Amazon review related to this issue. Our controller is designed to only allow ONE zone to run at a time (this is how a normal irrigation controller works). Running multiple zones at once is usually not possible due water-pressure limitations; which as you mention in your review (below), results in low water pressure.
As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want. Although we recommend 1 solenoid/valve per zone for scheduling purposes, the Gen2 controller will support up to two solenoids/valves per zone, plus a master valve, for a total of three solenoids at any given time.
The feature mentioned in this thread is related to pump delay in which a fixed time duration is programmed between zones so that the pump can refill. From the language used in your Amazon review (Without the delay feature each zone will not shut off completely when the next zone starts, what does this mean, multiple zones watering at the same time at very low water pressure, wasting all this water that everyone should be saving.), I believe you’re experiencing a wiring issue, unrelated to the controller’s scheduling.
I reviewed your controller’s logs and it appears you’ve been watering since 3/1/17, but do not have any active schedules. I will send you an email via support with a copy of the logs. Feel free to schedule a call with me at your convenience via this link to troubleshoot your wiring.
