Mode optimization
Why position optimize?
The purpose of the optimization functions are to reduce energy
consumption and noise generation in the ventilation system.
How does position optimization zone
work?
Position optimization is sometimes called two-step optimiza-
tion. The reason it is called two-step optimization is that both
damper position optimization on a zone and air handling unit
are active simultaneously. The zone damper (OS/OE) optimizes
its damper position depending on the damper positions on
the room products that are linked to the zone product and are
included in the optimization.
The zone damper position is changed by looking at the rooms’
damper positions. There is a safety function that controls
whether the zone damper’s air ow is more than 10% below the
underlying room product’s setpoint values. The position will then
not be reduced. If the most open room product has a damper
position above the upper limit, the zone damper opens more to
increase the air ow. If the most open damper is between the
lower and upper limit the position of the zone damper is not
changed. If the most open room product has a damper position
below the lower limit, the zone damper closes to reduce the air
ow.
This is selectable if WISE Damper is to present a measured ow
or whether it should present an added ow, based on the under-
lying rooms in SuperWISE.

How oen the zone damper may update its damper
position.
Optimization of
the damper
Step 3 1 20 % Installation/Installation
How many percent the zone damper may be allowed to
change between two updates.
Optimization of
the damper
Minimum
damper position
30 0 100 % Installation/Installation
The percent that the zone damper does drop below in
optimization.
There is a congurable ag on each product that indicates
whether the product should be included or excluded from the
optimization.
• Time between the setting of the damper position and size of
the step can be congured.
• It is also possible to use damper optimization without it
optimizing on the air handing unit.
• Damper optimization can only be enabled via the SuperWISE
conguration
• If damper optimization is enabled, the settings can be
congured through the SuperWISE interface. The settings are
in the zone.
