Question
Hi Jim,
I've had this controller for many years now. When I set the controller to manual and try to run a station the display is flashing 1C for station 1 and 2C for station 2. What does this error message mean? Normally the pump will come on ok. I've checked power supply to the pump and it's fine. Any ideas mate?
Cheers,
Dan

Answer
Hey Dan, First thing to check would be the relay at the pump. It could be shorting out the controller. Second thing would be the wires from the relay to the controller,making sure they are not cut or damaged. Third thing would be the wires from the controller to the valves. And finally check the solenoids on the valves themselves, if they are faulty they could also short out the controller. Good luck and have a great day.
