Question
Hi, I have just purchased a house with a 446pr50hz and am now having
trouble turning the system off. I have set all the settings to off including A
and B but one zone keeps reticulating. When I press pause, that zone
stops but a different zone starts up. 1A, 2A, 1B and 2B are all set on off.
The only way to stop any reticulation is to turn off the water mains. Do I
have a controller fault? Is there a valve i can turn off to cut off water to
just the reticulation? Many thanks!

Answer
Hi Ezra

Looks like you have a controller failure, but make sure you have only one start time in only one program. If you are in the US, your system should have some backflow preventer device before the irrigation valves, could be a vacuum breaker or an electric backflow valve, and should be a gate valve at the inline, so you can close the water to the system.
