CONTROL Optimize
CONTROL Optimize is a processor substation which via
Modbus communicates with the air handling unit and the
CONTROL Damper zone dampers in the Wise system.
CONTROL Optimize has knowledge of the position of each
zone damper, and optimizes the air handling unit’s pressure
rise so that at least one damper will always be fully open. This
reduces the power consumption of the air handling unit by up
to 25% and also contributes to making the ventilation system
operate more quietly.
CONTROL Optimize can manage up to 30 supply air and 30
extract air dampers respectively. The airflows, which are to
be added together or subtracted from one another to be
transmitted to a slave damper, must be split into groups. Each
group can manage 5 master and 3 slave dampers. A total
of 10 groups can be defined. A damper does not need to
be part of a group in order for optimising to work. A typical
product that should not be part of a group is a type PSFE
CONTROL Damper.
The built-in control equipment of the GOLD unit includes a
function that can be enabled for connecting CONTROL Opti-
mize. The pressure set points of the GOLD unit are then control-
led by CONTROL Optimize.

lers. Connect Mb 2 to the GOLD. Move the termination resistor
as shown in the figure.

unit. As an alternative, it can be connected to the bus contact in
one of the pressure sensors.

Settings in the GOLD
To enable communication, enter the settings in the hand-
held micro terminal of the GOLD under the Functions
Menu.
There is a special tab on the webpage for reading and
checking the performance of the connected CONTROL
Damper zone dampers.
Check that the function for CONTROL Optimize is enabled.
Connections
CONTROL Optimize can be connected to the GOLD unit via
Modbus contact Mb 2. Mb 1 is to be wired further down in
the system to CONTROL Damper. CONTROL Optimize is sup-
plied with a pre-wired Mb2 cable.

Settings in the GOLD via home page
All settings can also be performed via the home page for
the air handling unit. There are two tabs: [C Optimize],
where you can enable and view readings as well as [Fans]
where you can set limits for pressure regulation.
Supply airflow/pressure/% Extract airflow/pres-
sure/%
This shows the regulated pressure in Pa.
supply air/Extract air controller
Shows the control set point in Pa.
Supply air/Extract air, low speed
Not used by CONTROL Optimize
Supply air/Extract air, max. speed
Not used by CONTROL Optimize
Supply air/Extract air, high speed
These values specify the regulation start pressure for the
air handling unit during the countdown period before
optimisation takes place. This value is appropriately set as
a mean value between min./max.
Supply air/Extract air, C.Optimize min
Is the lowest pressure that applies to the min. airflow for
the entire system. The pressure can be set to 50 Pa at the
lowest.
Supply air/Extract air, C.Optimize max
Is the highest pressure that the system requires in order
to be able to supply the design max. airflow. It is impor-
tant to not set the pressure too high but instead is really
matched to the actual requirement. An excessively high
pressure can create unnecessary noise in the system if
some damper does not operate correctly and CONTROL
Optimize operates as if this damper were fully open.
Settings for optimizing
The basic settings for the damper positions used for opti-
mizing can be changed here. The changes are automati-
cally saved in the CONTROL Optimize.
DAMPER LIM.
Value for the limits within which optimising takes place.
If a damper is closed more than to 70%, the system
reduces the pressure set point of the fan and vice-versa
if a damper is open more than 90%, i.e. the system then
increases the pressure set point. These limits are preset to
70/90% and should not be changed.
STEP SIZE
The pre-selected pressure value for the change in set
point of the air handling unit pressure is 10 Pa and
Swegon’s recommendation. The value should not be set
lower than 5 Pa.
INTERVAL
Indicates how often CONTROL Optimize should read the
damper positions in the system. The lowest adjustable
time is 1 minute, which also is pre-selected. In larger
systems with more than 25 dampers, the time should
be lengthened by a minute or two, so as not to create
unnecessarily excessive traffic on the Modbus network.
START UP DELAY
This is the time needed for the system to become stable
before optimisation begins. When the air handling unit
has been shut down, all the zone dampers are fully open
and require time to adjust themselves to their set points.
Optimisation cannot start until the dampers have finished
adjusting themselves.
TIME TO START OPT.
Is the remaining time before optimisation begins the
countdown of the start delay.
