Circulation pump Grundfos ALPHA 3 25-60 180

ALPHA3 25-60 180

The ALPHA3 has built-in Bluetooth radio and is completely controlled by a smart device via Grundfos GO Remote App. It gives step by step assistance to pump configuration, maintenance and commissioning. The ALPHA3 communicates directly with the Grundfos GO Balance App, which enables the installers to perform fast and easy hydronic balancing.

AUTOADAPT function

The AUTOADAPT function which is integrated in the radiator and underfloor mode continuously adjusts the pump performance to the actual heat demand, i.e. the size of the system and the changing heat demand during the year. The AUTOADAPT feature will find the setting that provides optimal comfort with minimal energy consumption. In that, it also makes the commissioning fast, safe, and easy.

Features:

Radiator mode with AUTOADAPT the simple choice for two-string radiator heating systems
Underfloor mode with AUTOADAPT the simple choice for underfloor heating systems
Combined radiator and underfloor mode for systems with a combination of heating systems
In scheduling and summer mode a realtime clock makes it possible to select when the pump should operate and not to save energy
Simple user interface - the pump is completely operated from the Grundfos GO Remote App
Alarm and warning log with assistance via Grundfos Go Remote
No external motor protection required reducing installation time
High-torque start improves startup under harsh conditions
Dry-run protection during startup and normal operation
Maintenance free due to canned-rotor design and use of robust components
ALPHA plug makes electrical installation quick and easy
Insulating shells are supplied with pumps to minimize heat loss in heating systems

ALPHA 3 has three modes of adjustment that allow you to adjust the pump setting according to the type of heating system and the point of operation of the installation, they are:
- proportional-pressure control
- constant-pressure control
- constant-curve mode

The display shows the actual power consumption in Watts or actual flow in m3/h. LEDs indicate the actual operating status.
