3.1.3.2.2.4 Wiring to several circuits in parallel with, for each circuits, 2 fans whose
torques are independent
3.1.3.3 MODE CPs
The percentage of maximum torque of fan F1/F2 is modulated so as to maintain constant a certain
pressure value measured by a pressure sensor properly located in the ducting.

Choose the language (English, French, Dutch, German)
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 # FAN=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 (TQ, LS, CPs). Select CPs
If # FAN =F1 or F2=%F1 = yes. Select multiplier for CPs resulting torque when
terminals +12V and K3 are closed ('night' setup).
Select Y to configure time and date. See § 3.2.1
Select Y to activate the time segment scheduling function. See § 3.2.1
Select Y if you wish to activate the day OFF option. See § 3.2.1
Setup of CPs fan pressure instruction?
Define if the constant pressure assignment value (V) for the fans:
- is to be automatically determined as a consequence of a selected percentage of
maximum fan torque value.
- is to be typed in by the user: select PRESSURE
