It is designed for circulating liquids in heating and air conditioning systems. The Grundfos GO app offers numerous digital functions that simplify commissioning for both new and replacement installations. With the Grundfos GO app, you can easily check the best selection when replacing integrated and external circulator pumps; in addition, the exact pump curves can be easily adopted. The ALPHA2 GO has intelligent control modes: constant pressure, proportional pressure, constant flow rate and constant curve. Each control mode has adjustable setpoints. The AUTOADAPT setting, which is available for constant and proportional pressure, eliminates the need for manual selection of the pump setpoint. The PWM input enables precise external speed control, which further optimizes the overall system. The installation connector significantly simplifies installation without additional tools. Automatic self-venting and dry-running protection ensure quiet and reliable pump operation. The product features a robust start-up mode that prevents the risk of blockages due to contamination, magnetite or scale deposits. In the unwanted event of a pump blockage, the motor continuously attempts to start with the highest possible torque, ensuring start-up even under difficult conditions. The ceramic shaft and ceramic bearings are subject to only minimal wear. This increases the service life and reduces the likelihood of noise that can occur with wear due to increased bearing play. If the air detection and venting function of the system detects air in it, the circulator pump starts to pulsate to push the air more effectively to the nearest vent valve. The Grundfos GO app also offers the convenient option of checking the system based on the event log and historical data for flow rate, head, estimated fluid temperature and duty cycle.
