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.
