Air Temperature Control - Single Zone Manual System
Cabin tempe rature s election is made by turning the LH rota ry controller to t he required pos ition. Turning the controller counterclockwise wil l lower the tempera ture of t he air e xiting the heate r as sembly; turning the control ler clockwise wi ll rai se t het emperat ure of t he a ir exiting the he ate r as sembly.
Maxi mum he ating and cooling is represe nted on the control panel by a red a nd blue dot res pect ivel y.

The ATC module adjusts the temperature of the air exit ing t he heat er a ssembly by moving the pos ition of the tempera tureblend door. The tempera ture ble nd door dire cts a proportion of cool ed a ir from t he evaporat or t hrough the heat er core toproduce the required temperature output. The ATC module a djusts t he posi tion of t he t empera ture blend door by provi dingLIN bus mes sage s to the ble nd door ste ppe r motor. A Hall e ffect se nsor located wit hin the stepper motor i nforms t he ATCmodule t hat moveme nt of the st epper motor is taking place .
Air Temperature Control - Dual Zone Automatic System
Dual zone systems f eature 2 rot ary heat ing cont rolle rs, which a llow indi vidual climate control for the LH and RH sides of thecabin. Te mpe rature s election can be ma de by turning the controller to t he requi red tempera ture ma rked on the control panel.Turni ng e ithe r controller pas t the 16°C (61°F) mark will initi ate the maximum cooling s trate gy; turning either controlle r pa stt he 28°C (82°F) mark wi ll initiat e the maximum hea ting stra tegy.
• NO TE: Maximum cooling or hea ting can only be achieved i f both rotary control lers are set to t he s ame position.
The ATC module is a ble to maint ain constant te mpe ratures in both side s of the cabin by monit oring the fee dba ck f rom thecabin temperature se nsor. Unles s any manual overri des have be en s ele cted, the ATC module will a utomati cally control thei ntake ai r source , air dis tribution int o the ca bin and blower spee d to ma inta in t he requi red tempera ture s.

Blower Motor Control - Single Zone Manual System
Blower motor spe ed is se t by turning the RH rot ary cont rolle r to the require d position. The RH rotary controller allows t hes election of 14 blowe r motor spe eds . Turning the controller fully counte r clockwise will turn the blower mot or off.

Blower Motor Control - Dual Zone Automatic System
Blower motor spe ed is controlled automa tica lly by the ATC module unle ss a ma nual override ha s be en requeste d. Manualoverrides to blower motor speed can be made by turning the centra l rot ary cont rolle r to the require d position. The rota rycontrolle r all ows the manual sele ction of 7 blower motor spe eds . Turning the controller fully counte r clockwise will turn theblower motor off . W hen a manua l override has been ma de, the 'AUTO' LED loca ted in the ce nte r of the rota ry controlle r wil le xtinguis h.

The blower motor ca n be ret urne d to aut oma tic cont rol by press ing the 'AUTO' s witch locate d in the center of t he rotarycontrolle r. Under aut oma tic cont rol, the ATC module varies t he s pee d of the blower motor i n line with i ts 'comf ort' algorithmt o maint ain t he required cabin te mperat ure. The ATC modul e wi ll al so vary the blower motor speed to compens ate for the rame ffect on inta ke air produced by forward moveme nt of the ve hicl e.
