Activation of the A/C compressor regulator valve (N280)













• During operation, the compressor output is influenced by the A/C compressor regulator valve (N280).

• The Climatronic control module (J255) A/C control head controls the current flowing over the A/C compressor regulator valve (N280) and thus controls the output of the compressor (read the measured value block, display group "001").
