ADAPT
Constant curve mode
The AUTOADAPT function continuously adjusts the
proportional pressure curve and automatically
sets a more e cient one, without compromising
comfort demands. With this factory setting, in
80% of the installations no manual adjustments
are needed.
Proportional pressure mode is used in
circulating systems. The pump continuously
adapts its performance to the varying  ow
demand.
Constant curve mode is used when there is a
demand for constant  ow and constant head.
The pump is adjusted to the desired duty point
making pump throttling valves, which are
traditionally required in this situation, obsolete.
Constant temperature mode is used in variable
 ow systems within heating, where a constant
liquid temperature at a user-de ned point, is
desired. The pump is in charge of the  ow, and
external controller for temperature regulation
are made unnecessary.
Constant pressure mode is suited for variable
 ow systems with very low pipe pressure losses,
and in open systems where pipe pressure loss is
subordinate to static head.
FLOW
ADAPT is a combination of AUTOADAPT and
FLOW
LIMIT. The MAGNA3 continuously monitors
the  ow rate ensuring that it is not exceeded. This
will, in some cases, save the cost of a separate
pump throttling valve.

INTRODUCING:
YOUR PERFECT CONTROL MODE
Intelligent control saves time and energy
The MAGNA3 gives you the full range of control mode options you would expect from a state-of-the-art
circulator pump. But the intelligent modes – AUTO
ADAPT and FLOWADAPT – set MAGNA3 apart from the
competition. Furthermore, the FLOW
LIMIT and Automatic Night Setback control functions are applicable
with all MAGNA3 control modes.
