I bought this house 3 years ago with the sprinkler system already
installed, so I don't know much about it. It has worked for the last
few years. Now when I run station #2 another station (#3) always
comes on with it. When I run station #3 it runs by itself and station
#2 remains off. All other stations run as expected. I do not know
where to begin troubleshooting. Please help with your ideas.

Remove power from the control box. Wait 30 seconds or 10 minutes and
reconnect the power.

If you can't get the instructions for your brand of sprinkler, get
instructions for other brands. It's probably like other products
where one company akes more than one brand or at least one company
makes the logic modules for more than one brand.

Thanks,
