The E-2000/F series Aquastar Automatic Backwash Valves are pressure controlled systems which have the actuator and the controller in one enclosure. An integrated touch pad switch allows the operator to perform standard switching tasks on the unit (Backwash/Rinse cycl, drain, On/Off.). The internal pump control relay (max. 6.3 Amp) must control the recirculation pump on/off sequence during the valve backwash and rinse functions. An external pump contactor must be provided by installer (Aquastar 24V signal will provide operation). The auxiliary circuit available is a double throw relay, which can be used for external ball valve control (open make up water valves) 3-Way Ball valves or heater control (off function during backwash/rinse) or chemical feeders.
Equipped with adjustable potentiometers to set Backwash (1 min - 11 min.) and Rinse (20 sec - 4 min.).
