Key Features
Built-in Two-Way Communication System
The ALPHA3 features integrated wireless connectivity that links directly to the Grundfos GO Remote app. From the moment the circulator is installed and connected, all pump operations—including the setup wizard—can be controlled from your smartphone (iOS and Android). Pump settings can be changed quickly and easily, providing unprecedented control and convenience.
Market-Leading Efficiency
With an Energy Efficiency Index (EEI) as low as 0.15 for the 4-meter pump variant, the ALPHA3 delivers exceptionally low energy consumption compared to other pumps in its class. This translates to significant electricity savings and reduced environmental impact over the pump’s lifetime.
No Blockage – Robust Startup
The ALPHA3 features robust startup technology that reduces the need for emergency service visits. The pump’s intelligent motor control overcomes resistance from dirt, magnetite, or limescale build-up, ensuring reliable operation even after extended periods of inactivity.
No Dry-Running Protection
Built-in dry-running protection ensures the pump automatically protects itself from damage caused by operating without water. This safeguard extends pump lifespan and eliminates costly repairs from dry-run incidents.
Self-Adjustable AUTOADAPT Technology
AUTOADAPT automatically finds the best pump setting to maximize both comfort and energy efficiency. The system continuously monitors heating demand and adjusts pump performance accordingly, eliminating manual adjustment and ensuring optimal operation at all times.
