Fault finding – System operation and track allocation
System operation
The manual heating and ventilation system does not have a computer. It consists solely of a control panel from which
the compressor (controlled by the Protection and Switching Unit and injection), the passenger compartment heating
resistors (controlled by the UCH with permission from the Protection and Switching Unit and injection) and rear de-
icer (managed by the Protection and Switching Unit) are started as explained in the synopsis of heating and
ventilation system operation in Section 62A.
The panel, by means of cables, also controls the air distribution flaps, air distribution and recycling, as well as fan
assembly speed through a connecting wire and resistor unit.
