E. Temperature Slide Control and Air Volume Switch
The temperature slide control (N19) comprises a slide potentiometer, electronic components and a relay which switches the clutch of the refrigerant compressor on and off.
As a result, the temperature set on the temperature slide control is maintained.
A vacuum switch is located on the air volume slide switch (S3) in connection with the air conditioning system.if the lever on the air volume slide switch is at the left-hand stop ("min"), the fresh air/recirculated air flap is closed (fresh air closed). If the lever is moved in the direction of the 1st blower stage, the vacuum switch will disable the vacuum before the blower cuts in and the fresh air/recirculated air flap is opened (refer to vacuum diagrams, section K).
