3.1.2.2
LS MODE
The assigned airflow is a function of a 0-10V linear signal. The user defines the link with 4 parameters:
Vmin, Vmax, m³h≡Vmin and m³h≡Vmax, applied to the following diagram.
Principle diagram:
Using the advanced setup,
upper and/or lower limit.

With m³h≡Vmin < or > m³h≡Vmax (positive or negative link).
it is possible to stop the fans once the input signal value has reached a certain
upper and/or lower limit.
Choose the language (English, French, Dutch, German)
If yes, the airflow of the fan will be displayed.
If yes, the pressure of the fan will be displayed (not available for fans 720999 and
720998)
If yes, the speed of the air of the fan flow will be displayed
If DISPLAY Pa = yes, enter the area of the blowing duct.
Choice of the fan type (CID – see label on fan or
fan with speed feedback or 720998 for generic backward fan with run
contact
).
Select number of fans connected to CB (F1 or F1+F2).
If # VENT=F1 + F2. Choose yes in case of dependent fans: the airflow of fan 2 is
defined as the airflow of fan 1 per a ratio defined in menu item %F2/F1. Choose no
in case of independent fans: the 2 fans have their own setpoints.
Choice of the working mode (CA, LS, CPf, CPs). Select LS
Select minimum voltage value for LS link
Select maximum voltage value for LS link
Select airflow for each F1,F2 fan corresponding to Vmin
Select airflow for each F1,F2 fan corresponding to Vmax
720999 for generic backward
