SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Have you tried the basics?
1. Are ALL shutoff valves on? At a minimum, there should be a system valve that must be open, and your backflow preventer usually has shutoff valves on them as well. Typically, the handle for a shutoff valve must be turned so that the handle is parallel to the direction of water flow for it to be "on" (when the handle is perpendicular, it's like a wall, to stop the flow).
2. Will the zones come on if you try openning the control valve manually?
3. Is the controller properly plugged in with any fuses still in tact (I don't know about the Pro C specifically, but if a controller is on battery power, it might look like it's still functioning, but would not operate the zones because it doesn't have enough power, same goes if the fuse is blown, the fuse can be just for power to the valves and not affect the internal operation of the controller).

Turn the water on, and know that it is on by manually opening a valve without using the controller. Make sure a rain detector isn't preventing operation.

Can't be done - write down your settings, then reprogram the controller - it has been many years since controllers with separate switches for each zone have been sold, and if you could buy them today, they would be so expensive you would never spend the money.
