Controls

System KB work is supervised by means of the controls located on the panel. The electromagnet of coupling of the compressor and the fan electric motor are connected by wires to the control panel. In the switched off position of a regulator the Electric chain вентилято ра is opened. Air giving обеспечи вается at regulator inclusion in one of four working positions. Cooled and dried air arrives in car salon at inclusion maximum (MOVE), normal (NORMAL), combined (ВI-LEVEL) modes or a mode blowing windscreen (thawing) (DEFROST). Air temperature is established by means of the rotary regulator located on the control panel. The regulator handle is connected приводным by a cable with mobile заслонкой on which position air expense through heat exchange ник a heater depends. At moving of a regulator from one extreme position in another тросовый the drive should provide a full range of movings заслонки. Position заслонки a temperature regulator does not depend on the switch of operating modes. The privodnoj cable заслонки passes on the right side of the conditioner block. On some models of cars заслонка it is supplied by an electric drive of moving, thus the cable is absent. On some cars the electric fan of system of cooling of the engine does not enter about structure of system of SQ. Themes But less the fan automatically gets into gear at system KB inclusion in maximum (MАХ), normal (NORMAL) or combined (BI-LEVEL) a mode. On some cars the fan starts to work and at mode inclusion blowing windscreen (thawing) (DEFROST). This feature of a control mean system KB allows to prevent an overheat of a head of the compressor. Thus system KB works more effectively. On separate models of cars the electric fan of the engine is automatically switched off at achievement by the car of speed of 56 km/h when intensity of cooling of the condenser a running stream of air becomes sufficient. Fan work the electronic block (ECU) through the fan relay operates.

Vacuum pipelines

Vacuum pipelines through колодку are attached to the switch on the control panel by system of SQ. tightness At infringement or destruction of the separate pipeline it is unessential to replace all complete set of pipelines enough to cut off a faulty site of the pipeline and to insert instead of it a plastic connecting tube. If it is necessary to replace all pipeline, it is necessary to cut off all pipelines from Pads and then to attach them directly to the vacuum switch.

Vacuum receiver

At sharp dispersal of the car depression in the inlet pipeline of the engine decreases. Thus the return valve disconnects a vacuum receiver from the engine, providing possibility of normal work of a vacuum drive of management with system SQ.
