I’m trying to schedule 2 zones at the same time (3+4) but I can only get zone 3 to operate than zone 4.
In addition if zone is activated and I would like manually to add activate additional zone I cannot do it unless I manually stop the active zone and activate the other zone..
Am I missing something?
The 801/819 series supports activating only one irrigation zone at a time; it does not support simultaneous multi-zone irrigation. When multiple zones share the same schedule, they will activate sequentially according to the zone order.
Unfortunately, the 801/819 series controllers are designed to support the operation of only one irrigation zone at a time.
We greatly appreciate your feedback and have duly noted it for future reference in our product development. However, at this time, this product does not support simultaneous irrigation across multiple zones.
Currently, all of our multi-zone irrigation controllers are designed to activate only one zone at a time, cycling through them according to the scheduled program. If multiple zones were to operate simultaneously, the water pressure would likely drop significantly; this would result in insufficient water flow to each individual zone, thereby preventing effective irrigation.
We regret to inform you that we do not currently offer controllers that support simultaneous irrigation across multiple zones. We can only suggest that you adjust your irrigation schedule and watering intervals accordingly.
