OVERVIEW
The clima te cont rol s yste m i ncorpora tes the hea ting, ve ntila tion and A/C systems. There are 2 mai n types of clima te controls yste m a vail able ;
a single z one ma nual sys tema dua l zone a utomati c system.
The clima te cont rol f unct ions for bot h systems a re controlle d by the ATC modul e. The ATC module is mounted in the ce nte rcons ole a nd cont ains bot h the syste m e lectronic sof twa re a nd user cont rols .
The ATC module works in conjunction wi th a number of othe r ve hicle control module s, i ncluding the Engine Control Module(ECM), which control s a number of cl ima te control sub-s yste ms on recei pt of reques ts f rom the ATC module .
The s ingle zone climate cont rol s yst em f eat ures ma nual control for air t empera ture , air dist ribution and air source, although as mal l amount of aut oma tic control does exis t in the ATC softwa re. In re sponse to s yste m i nput s, t he ATC module cont rols theopera tion of 3 st epper motors mounted on t he heat er as sembly. The st eppe r motors then a djust the positi on of the ai rt emperat ure, air dist ribution and air source flaps accordingly.
The dual zone cl imat e control system fe atures a utomati c control of air t empera ture , air dis tribution and blower motor s pee d.The ATC module is a lso able to cont rol i ndividua l te mpe rature re que sts for both the dri ver a nd pass enger s ide of the cabin.
• NO TE: The ATC module can only maint ain a maximum tempera ture dif fere nce bet wee n the 2 side s of the cabin of up toa pproximate ly 3ºC (4ºF). This is due to the moveme nt a nd mix of a ir wi thin the cabin.
The dual zone cl imat e control system fe atures 2 additional sens ors; a cabin temperature se nsor and a sunload sensor. Thecabin temperature se nsor provides a temperature fe edback to e nabl e the ATC module s oftware mai ntai n a cons tant ca bint emperat ure. The sunloa d se nsor provide s a rea ding of s ola r loa ding on the vehicle occupants a nd enables the ATC module toa djus t the output from t he clima te control s yste m a ccordingly.
Higher specif icat ion vers ions of t he dual zone cl imat e control system are al so a vailable . These syst ems fea ture 2 morea ddit iona l se nsors; a polluti on s ensor and a cabin humidity sensor.
The pollution sensor det ects pol luta nts ente ring the cabin, allowing the ATC modul e to rea ct by cha ngi ng t he posit ion of thea ir intake fla p. The cabin humidi ty s ensor ca lcul ates the probability of misti ng on the winds hiel d.
