Winter
Leaves all the ports open. This setting is used whenever the filter is shut down for extended periods of time.
Closed

Backwash

Recirculate
Bypasses the filter but allows water to recirculate. This setting is used when a Koi disease treatment that is harmful to the filter bacteria is added to the pond,.
