Self Adjust

Typical functions for a controller include opening and closing solenoid valves, managing filter backwash cycles, water budgeting according to zone characteristics and changing weather conditions. The chief challenge with controlling greywater is that the supply is not always reliably there at a predictable time. The controller must be able to sense when the basin is full of water and then determine the correct zone to irrigate. Smart Controllers are able to self-adjust according to changing weather conditions, and seasonally changing evapotranspiration rates, usually based on realtime ET (evapotranspiration) values taken from active weatherstations, historical climate data for the appropriate CIMIS zone location, and/or soil moisture sensors. Some systems use a water meter that measures all graywater and alternate water that is distributed to each zone.
