3. Product introduction

3.1 Product description

ALPHA 15-58
ALPHA is a high-efficiency circulator fitted with an electronically
commutated motor and designed for circulating liquids in heating
systems.
The pump features the highest HI energy rating on the market.
ALPHA is designed with intelligent controls featuring constant-
pressure, proportional-pressure and constant-speed curves, each
with three speed settings as well as an AUTOADAPT setting,
removing the need to manually select the pump setpoint.
The new toolless, removable power connector results in fast and
easy installation. Fewer callbacks can be expected due to its robust
startup, self-venting ability and dry-running protection. The system
air detection and venting mode can be activated through the
Grundfos GO app. Grundfos GO also provides the ability to
conveniently troubleshoot the system through the event log, run
guided setup, set custom control modes and run firmware updates.
Historical trend data for flow, head, estimated media temperature
and on-cycle durations are available through the app.
A terminal box with conduit connections is provided for power
connection.

3.2 Intended use

The pump is designed for circulating liquids in heating and air
conditioning systems.
