Introduction
Grundfos UPM3 Auto 15/70 is a compact,
energy-saving and high-performance pump spe-
cically developed for the OEM market. LK uses
UPM3 Auto in several products because of its
good characteristics.
The pump has ten different setting options, three
curves for Proportional Pressure, three curves for
Constant Pressure and four curves for Constant
Curve. The recommendation for underoor heat-
ing is Constant Pressure and a curve that is adap-
ted to conditions for the installation. The pump is
set to Proportional Pressure, curve three, on
delivery.
Operating mode / Settings mode

tion the setting currently in use by the pump.
