Please note that to create a filter program, the following must be created first:

• “Filter” Mainline
• Valves for each of the backflush valves on the filter station
• DP (Differential Pressure) sensor

There are two scenarios that will be explained below:

1. Creating a Filter Program where flushing is managed by an external flush controller
   1. In this case, Farmsync only sends a start & end command
2. Creating a Filter Program that issues all commands from Farmsync
   1. In this case all the flush times are set on Farmsync
