Self Study Program 25 – Air conditioning of the FELICIA and OCTAVIA

VAG SSP 25. This fully automatic air conditioning system is presented to you in this Self Study Programme. It provides you with information regarding the controls, the operation and self-diagnosis.

You will be familiar with the refrigerant circuit of an air conditioning system from the manual air conditioning of the FELICIA and OCTAVIA. The fundamental design of an air conditioning system was explained in Self Study Programme No. 10, while Self Study Programme No. 11 presented the specific air conditioning system in the FELICIA.

The technical perfection of an air conditioning system is the Climatronic. The main highlight of this version is the electronic control, which performs the task of blending the cooled and heated air to the desired comfort temperature, a task which is performed manually on the conventional air conditioning system.

This also is why the system is called Climatronic. The principal parameters of the electronic control are the constant comparison of the temperature between set and actual for the purpose of automatically regulating the temperature of the air flowing in, of the air volume and the distribution.
