Air control
4 Air control
A central protective system such as the FCU 500 takes
over air control. It monitors the static air pressure as
well as the air volume required for pre-purge, start-up
and after the furnace has been shut down. The air ac-
tuators (BCU..F1 = actuators IC 20/40, BCU..F2 = RBW
actuators, BCU..F3 = valve) are actuated for this pur-
pose by the capacity control system of the BCU.
After being enabled by the protective system, the BCU
can start the burners. The capacity is controlled during
operation by an external temperature control system.
