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. The ATC module monitorst he s igna l from t he cabin humidi ty s ensor and a djus ts blowe r speed, air dis tribution and A/C compress or di spla cementa ccordingly.
Stop/Start Vehicles - From 2010 MY
To support the Stop/Start system, a number of changes have be en made to the logic and opera tion of climate cont rol s yst emwithi n a Stop/Sta rt cycle to:
maint ain occupant comfortpreve nt winds hie ld mistingconse rve batt ery power.
This has bee n achieved by the ATC (automa tic t emperat ure control) module monitoring and varying when nece ssary, va riousclima te control funct ions wit hin a St op/Start cycle.For a ddit iona l inf ormation, re fer to: Starting Sys tem (303-06C Start ing Syst em - TD4 2.2L Diese l, Vehicles Buil t From:01-03-2009, Des cript ion and Ope rati on).
To maint ain the cabi n te mpe rature when the engine is s hut down in a St op/Start cycle, an a uxil iary electric coolant-pump hasa lso bee n int egra ted into the cooling system to mai ntai n the coolant flow t hrough t he cabi n’s heat er core. The pump isdirectly hardwire d to the ECM. O n ve hicl es fi tted wit h a FFH (fue l fired heat er), the FFH coolant pump i s uti lize d and activa tedvia t he FFH.For a ddit iona l inf ormation, re fer to: Starting Sys tem (303-06C Start ing Syst em - TD4 2.2L Diese l, Vehicles Buil t From:01-03-2009, Des cript ion and Ope rati on).

ATC MODULE

The ATC module is mounted in t he cente r console a nd is int egra l wi th t he control panel . The modul e works in conjunct ion witht he ECM to control a ll as pect s of hea ting, ve ntil ation, and A/C.

Ope rati on of the solenoid valve is cont rolle d by the ECMusing a P ulse W i dth Modulat ed (PW M) s igna l of diffe ring va lues . By controll ing the flow of refri gera nt (displace ment) t hrought he compress or, the sole noid va lve can cont rol e vaporat or opera ting temperature and cabin humidit y by va rying the pre ssurewithi n the A/C syste m.
• NO TE: The A/C compre ssor sol enoid va lve is fi tted to i6 petrol vehicle s only.
For a ddit iona l inf ormation, re fer to: Air Conditioning (412-01 Cli mat e Control, Description a nd O peration).
REFRIGERANT PRESSURE SENSOR

The refrigera nt press ure sensor provides the ECM wi th a pre ssure input from the high press ure side of t he refri gera nt s yste m.The pres sure sensor is locat ed in the ref rige rant line be twee n the conde nse r and the thermosta tic expa nsion valve .
The ECM supplie s a 5 V reference fe ed t o the pressure s ens or a nd recei ves a re turn signal volta ge, bet wee n 0 V and 5 V,relat ed t o system pressure. The ECM use s the s igna l from t he s ensor to protect the ref rigerant sys tem from extremes ofpress ure .
If the pre ssure withi n the re frige rant sys tem exceeds the minimum or maximum pre ssure li mits , the ECM will;
disable the A/C compress or (TD4 vehicles )re duce A/C compress or di spla cement (i6 vehi cles ).
If a reduction in A/C compre ssor displace me nt fa ils to bring the sys tem back into it's optimum pres sure range, the i6 ECM willdisable t he A/C compres sor.
The ECM constantly sends a refrigera nt s yst em pres sure signal to the ATC module. The signal i s tra nsmitte d from the ECM tot he Cent ral Junct ion Box (CJB) over the high spe ed CAN bus . The CJB acts a s a gate way and provides t he press ure signal t ot he ATC module over the me dium speed CAN bus.
If the pre ssure withi n the re frige rant sys tem rise s a bove its ma ximum press ure limit, the ATC module will incre ase thea mount of re circulate d a ir enteri ng t he cabin. This helps lower t he press ure wit hin t he refrigera nt s yste m a nd t hus helps toa void ha ving to disa ble t he A/C compres sor.
EVAPORATOR TEMPERATURE SENSOR
The e vaporat or t emperat ure sensor is a Negative Te mpe rature Coef ficie nt (NTC) the rmistor. The se nsor is mounted on the LHs ide of the heate r ca sing, and meas ures the temperature of cooled air once it has t rave led ove r the evaporator. The se nsorrecei ves a 5 V re fere nce feed from the ATC module. By monitori ng t he returned volt age , the ATC module ca n ca lcul ate theresis tance of the sensor and hence e vaporat or t emperat ure.
