What do all the settings on top of Sand filter and mean?

- Backwash: This setting is used to clean the sand filter by reversing the flow of water through the filter. This helps to loosen and remove dirt and debris that has accumulated in the sand.

- Rinse: This setting is used to rinse the sand filter after it has been backwashed. This helps to remove any remaining dirt and debris, and to ensure that the filter is clean.

- Filter: This setting is used to filter the pool water. The water passes through the sand filter, and the sand traps any dirt and debris.

- Waste: This setting is used to bypass the sand filter and send the pool water directly to the pool drain. This is useful when you need to drain the pool or when you are adding chemicals to the pool.

- Recirculate: This setting is used to circulate the pool water through the sand filter without filtering it. This is useful when you want to circulate the water to keep it from becoming stagnant.
