4.1.2.3 Operating LS mode with CBr master
The assignment value for the supply constant airflow is a function of a 0-10V signal connected to terminals K2 and
GND of the CBr. The link between voltage and airflow is linear. The exhaust constant airflow is equal to %EXT/PUL
of the supply airflow. (Except if 2 separate 0-10V signals are used to determine exhaust and supply constant
airflows, see advanced setup).
Starting/stopping the fans is carried out with entry K1 on the CBr. The K3 entry of the CBr can be used to activate
the pre-set multiplier (% on K3).
