PRINCIPLES OF OPERATION
To accompl is h t he transfer of heat , the refrigerant is ci rculat ed around t he sys t em, where i t pas s es t hrough 2pres s ure/t emperat ure regi mes . In each of t he regimes the refrigerant changes s t at e, during which process maxi mum heatabsorpti on or di s si pat ion occurs .

The cabin te mpe rature s ensor comprises a NTC thermist or a nd a motor. The sensor is mounted behind a grill on the driverss ide of the instrume nt panel , adjace nt t he s teering column.
• NO TE: The cabin te mperat ure sens or i s only fi tted to vehi cles with a dual zone, a utomati c cli mat e control system.
The motor is provide d an ele ctrical f eed from the ATC module and draws ca bin a ir in through the grill a nd over the thermis tor.The t hermist or re ceives a 5 V re fere nce feed from the ATC module. By moni toring the re turned volt age, the ATC modul e ca ncalculate air tempera ture wit hin the cabin.
CABIN HUMIDITY SENSOR
The cabin humidity s ens or is located wit hin the inte rior mirror a nd comprise s 3 individual el eme nts :
A humidit y se nsorAn ai r temperature se nsorA windshi eld glas s te mpe rature s ens or.
• NO TE: The cabin humidity sens or i s an opt iona l fit onl y.
The readings from these 3 s ensors combine to reduce the ri sk of mi sting on the windshield.
The humidity sensor element is cont aine d behind a nylon mesh cove r. The s ens or comprise s an ele ment made up of fil mcapa citors on dif fere nt s ubst rate s. The diele ctric is a polyme r which abs orbs or rele ases wa ter proportional to t he humidity oft he a ir being dra wn t hrough the sensor. This causes a change in the capacit ance of the sensor.
Humidity wit hin the cabi n is controll ed by ra ising or lowering the te mpe rature of the evaporator. An increas e in eva poratort emperat ure increase s the moist ure cont ent of t he a ir in the cabin. Lowering the evaporator tempe rature re duces t he mois tureconte nt of the ai r in the cabin.
The capa cita nce of t he s ensor, t oget her with both te mperat ure values, are provided as LIN bus me ssages t o the ATC module.The ATC module use s these signals to calculate the dew point of the ai r at the windshi eld. W hen t he t emperat ure of t hewindshie ld glass rea ches or falls bel ow t his value, misti ng i s likely to occur. In this inst ance, the ATC module will;
