4.1.2.2 Operating LS mode with RC module master
•
Starting/stopping the fan is carried out with knobs I/III and OFF.
•
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).
•
By pressing knob III of the RC you activate the pre-set multiplier (% on K3).
•
It is possible to start/stop the fans with an external contact connected to the CBr (see diagram hereunder).
Caution: terminals K1/K2/K3 of the CBr CANNOT be connected.
CBr
a) Wiring diagram with 1 CBr connected to 1 sensor
b) Wiring diagram with several CBr connected in parallel to 1 sensor
(*) K2 0-10V signal, maximum impedance allowed: 1500
Closed = fans OFF
Open = fans ON
Caution: use goldplated contacts only
