CONCLUSION
CONTROL PANEL IS AN IMPORTANT TOPIC IN CLIMATE SYSTEMS
Depending on Client Style and ergonomy, each car and range One to be changed in each restyling ( every 3 years ) With a larg variety, options, in a perpetual evolution, much evoluting
CP is seen in the car and first seen in the climate system chain Where the spent cost in aspect and materials, is seen
One of the main supply Mixing many technologies and skillness
( decoration, lighting, mechanisms, electric, electronic, soft, comfort )
ALL RESULTING IN DIFFICULTIES TO OBTAIN : GOOD SUPPLIERS OFFERING A COMPLETE SYSTEM WITH QUALITY / PIECE PRICES / INVESTMENTS / SHORT DELAYS
