8.3.2 Outdoor Temperature Compensation
Airflow
Outdoor temperature compensation of the airflow can be
activated if it is desired to reduce the airflow in the winter-
time.
In the flow regulation mode, the current airflow is
reduced. In the pressure regulation mode, the current
setpoint for pressure is reduced.
The function has no effect if the airflow is demand-con-
trolled.
The airflow is reduced as a percentage of the current
airflow/pressure.
Settings:

Y1, max permissible reduction 0-50% 30 %
X1, breakpoint -30 – -10 °C -20 °C
X2, breakpoint -10 – +15 °C +10 °C
8.3.3 Boosting
The airflow is regulated between two flows in response
to a 0-10 V DC input signal from an external source, such
as a potentiometer (connected to control unit terminals
30-33).
Boosting can be used, for example, in assembly halls,
where a higher rate of air change is needed under full-
load conditions.
The function is activated only when the unit fans operate
at high speed.
On a 0-10 V DC signal, the fans are gradually accelerated
from the unit’s initial high speed setting to its initial max
speed setting. On a max input 10 V DC signal, the unit
fans operate at max speed.
The function must be activated separately for the supply
air fan and for the extract fan.

Outdoor air compensation according to factory settings
involves:
Outdoor temperature +10 °C (Breakpoint X2): Compen-
sation starts and gradually proceeds between 0–30 %
down to outdoor air temperature -20 °C.
Outdoor air temperature -20 °C (Breakpoint X1): Con-
stant compensation proceeds at 30 % (max reduction
Y1).
