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 verify the best selection when replacing integrated and external circulator pumps; in addition, the exact pump curves can be easily adopted. The ALPHA2 GO features intelligent control modes: constant pressure, proportional pressure, constant flow rate, and constant curve. Each control mode has adjustable setpoints. The AUTOADAPT setting, available for constant and proportional pressure, eliminates the need for manual selection of the pump setpoint. The PWM input allows for 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 is characterized by a robust starting mode that prevents the risk of blockages due to impurities, magnetite, or scale deposits. In the undesired 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 minimal wear. This increases service life and reduces the likelihood of noise that can occur due to wear caused by increased bearing play. If the system's air detection and venting function detects air in it, the circulator pump begins to pulsate to more effectively push the air to the nearest vent valve. The Grundfos GO app also offers the convenient option to check the system based on an event log and historical data for flow rate, head, estimated media temperature, and operating time.
