The control unit ( A-Fig.10) implements the heat regulating strategies according to input received from the following
sensors:• outside air temperature ( B-Fig.10)
• internal air temperature (RH and LH) ( C-Fig.10)
• Vent outlet air temperature ( D-Fig.10)
• Solar irradiation ( E-Fig.10)
The control unit memory contains a resident program, composed of a set of strategies, each of which manages a V S H F L ¿ F I X Q F W L R Q R I W K H F R Q W U R O V \ V W H P
The strategies process a set of parameters by means of the above inputs and memorized data maps. These
parameters control the system actuators (outputs), that is those devices causing the system to reach and hold a comfortable temperature inside the passenger compartment. The devices are the following:• Air distribution actuator ( F-Fig.10)
• Motor fan ( G-Fig.10)
• Recirculation actuator ( H-Fig.10)
