A combination pump logic controller and vfd, part of the company’s microprocessor-driven pump controller line, can control up to three pumps in parallel, says the manufacturer. The Technologic® 500 Series features both manual and automatic pump alteration in a single enclosure. It has two discrete analog inputs for zone sensors and one analog sensor for a flow sensor. The controller is designed to safeguard against damaging hydraulic conditions. A memory storage function prevents accidental loss of data caused by voltage storage surge or spike, says the company.
