ALPHA is a high efficiency circulator fitted with an electronically commutated motor and designed for circulating liquids in heating systems. The pump features the highest HI energy rating on the market. ALPHA is designed with intelligent controls featuring constant-pressure, proportional pressure and constant speed curves, each with three-speed settings as well as an AUTOADAPT setting, removing the need to manually select the pump set point. The new toolless, removable power connector results in fast and easy installation. Fewer callbacks can be expected due to its robust start-up, self-venting ability and dry-running protection. The system air detection and venting mode can be activated through the Grundfos GO app. Grundfos GO also provides the ability to conveniently troubleshoot the system through the event log, run guided setup, set custom control modes and run firmware updates. Historical trend data for flow, head, estimated media temperature and oncycle durations are available through the app. A terminal box with conduit connections is provided for power connection.
