3. Product introduction

The MI401 ALPHA Reader unit is the receiver and transmitter of pump

performance data. The unit broadcasts to an Android or iOS-based mobile

device via Bluetooth. The unit uses a small lithium battery.

The unit is together with the Grundfos GO Balance app used for balancing

heating systems primarily in one-family houses. The app guides you through

a number of steps where information on installation and measurements from

the pump is collected. In a two-string system heated by radiators, the app

calculates the balancing values for each of the valves. On the basis of these

values, the app guides you through the adjustment of each valve in the

system.

The app is available for both Android and iOS devices, and you can

download it from Google Play and App Store.

Note

Only use the unit with Alpha 2 Model E and ALPHA3 circulator

pumps.

Note

The Bluetooth range is affected by the materials in walls, roofs and

floors as well as the type of mobile phone and the weather

conditions. In the worst case, the Bluetooth range might be shorter

than the specified range. If this is the case, use a second unit as

signal repeater.

Note

You can only do hydronic balancing in two-pipe heating systems.
