Use the Quick Cycle feature which is available from the "Actions" tab. Enter in 1 minute for each zone and click the Run button. The next time your controller contacts LawnCheck, the cycle will be retrieved and will be executed. Your controller contacts LawnCheck once every 5 minutes and so your Quick Cycle can begin execution at any time with a maximum delay of 5 minutes.
