PM START The Grundfos pressure manager PM START is designed for automatic on/off control of Grundfos pumps and other pumps for water supply. PM START is a basic control solution suitable for applications where demand-based on/off pump control is required. PM START switches on the pump when a cut-in pressure of 1.5 or 2.2 bar is reached. The pump runs as long as there is sufficient flow. PM START switches off the pump in case of water shortage and protects it from dry-running. In the event of a brief power outage, the pressure manager automatically resumes operation as soon as power is restored.
