This is our original flagship model. It is designed to stand alone in the pump equipment room. Housed in a NEMA 3R enclosure with touch screen interface and manual by-pass switch. Connected to the flow sensor, heaters, chemical controller and pump motor. The FD takes feedback from these items and will then cause the pump and motor to operate in a way that maintains the required flow rate of the pool. The FD can be set up as a single pump system, dual pump system, manual alternating pump system, fitted with under voltage/phase loss protection and can have an A/C unit attached for hot environments.
