X-Core - System Off The X-Core controller will not water manually or automatically with the dial in the system off position. Valves currently watering will be shut off after the dial is turned to the system off position. The display will flash OFF for two seconds then remain solid. Any active program is discontinued and watering is stopped. To return the controller to normal automatic operation, simply return the dial to the run position. Once the dial is back in the RUN position, then the controller will resume the normal programs at the next scheduled start time.
