Just fired up the controller for the spring and when manually running through zones they wouldn't shut off. Zone one when manually stopped would say running even when zone 2 was started manually. The only way to shut them down was to unplug the controller. Same thing happens when running manually on the controller. Ultimately the more zones tried, the more zones on at the same time.
I did have to replace the power supply this winter as it fell out of the outlet and wouldn't provide D.C. Replaced with a 24v 1 amp adaptor. Controller lights up fine. Gen 2.
