* This special cable with an active built-in NTC protection
circuit, reduces possible inrush currents. To be used in case of

5.5.4 ALPHA Reader
Fig. 15 ALPHA Reader
When performing hydronic balancing in a heating system, the
Bluetooth signal between the pump and the smart device may
become too weak due to the maximum Bluetooth range of
approximately 10 m. In such cases the ALPHA Reader can be
used as an extender.
The ALPHA Reader is the receiver and transmitter of pump real
time performance data.
The unit uses a CR2032 lithium battery.
The unit is together with the Grundfos GO Balance app used for
balancing heating system primarily in one- and two-family
houses. The app is available for both Android and iOS devices,
and you can download it free of charge from Google Play and
App Store.
See separate installation and operating instructions.
