Highlights
Automatically learns and calibrates your specific pump data to set exact overloads without manual input
Works with standard float switches, pressure switches, and probes, alongside an integrated 4-20 mA input for precision transducer level control
Actively guards against dry running, dangerous current spikes, voltage drops, phase failure, and overheating (via Klixon connection)
Supports single phase pumps up to 2.2kW (3HP) and three phase pumps up to 15kW (20HP)
Features a dedicated, volt-free BMS output for seamless building management system automation
