Question
I have a 6 zone Toro Ecx sprinkler system with 3 programs. I used A for the normal watering schedule and B for just using a hose in one zone. Suddenly the only programme that is appearing on the display is C and I cannot use the others. I reprogrammed A on C but need another program for what I used B for. Are these circuits replaceable?

Answer
Hey Silvia, once the board (circuits) go bad, you must replace the whole controller. Before you do this, try this. First remove the 9 volt back up battery, and then turn off the power to the unit. Leave the power off for about a minute. Then with the battery still removed, turn the power back on, and see if the programs return to normal. If they do, install a new battery and program the controlleer. If after you try the operation above, and it still doesn't work right, thenthe controller need to be replaced. Good luck and have a great day.
