    Setting the Stack and Overlap Mode

    WeatherTRAK Controllers

    PDF es:

    The WeatherTRAK controller's Programs (found in the Days/Times section of the Program page) can operate in either Stack or Overlap


    These settings do not affect multiple manual irrigation stack/overlap behavior and are not required for OptiFlow enabled controllers.

    Setting Descriptions


    This setting means your Programs will run in sequence, one right after the other (A, B, C...etc.) The first Program will complete its irrigation cycle, followed by the next Programs (if in use), 

    Program A's Water Windows and Water Day Mode are only available in this mode. The other Programs will follow Program A. However, their Mainlines and Pump Starts remain independent. 

    This is typically used when the mainline capacity will only accommodate a single station running at a time.


    This setting means your Programs are set up independently and can run in parallel if desired. If one Program is still operating when another Program is scheduled to start, the two Programs will still run together. 

    Each Program's Water Windows and Water Day Mode are available to be set independently, as are their Mainlines and Pump Starts.

    This is typically used when the mainline capacity can accommodate more than one station running at a time - and as long as the overall electrical draw does not exceed 3.0 amps.
