Description - HEATER - Alfa Romeo GT 2.0 JTS

The vehicle climate control system is achieved through the duct/distributor unit and heater.The climate is controlled by means of three control knobs on the facia:the left knob controls the hot and cold air mixing flap;the right knob controls the opening of the flaps that regulate the distribution of air flows;the centre knob regulates the air ventilation at four different speeds;the right button switches the heated rear windscreen on and lights up the LED..If the centre button is pressed it switches on the air recirculation function; the LED comes on when the button is pressed. If the button is not pressed, "dynamic" air from the outside flows through.A special control unit manages the operation of the system by controlling:air distribution at the vents;fan speed (continuous variation);air recirculation engagement;The control unit sets the above parameters so that temperature of the passenger compartment is adjusted to the desired temperature. Depending on the set requirements, the control unit establishes the inlet speed for the air into the passenger compartment via the engine fan and the temperature by means of a mixture actuator; the distribution of the flows is also set by another actuator and, lastly, the interior air/exterior air recirculation function by a final actuator.For more details

Operational description - HEATER - Alfa Romeo GT 2.0 JTS

The climate control system control unit M70receives an ignition-controlled power supply (INT/A) at pin 3 from the line protected by fuse F31 of the junction unit under the dashboard B2.''; receives a direct supply at pin 2 from the line protected by fuse F39 of the junction unit under the dashboard B2.Pin 1 of M70is earthed.The recirculation actuator N82is operated by control unit M70from pins 14, 15, 16 and 17.The mixture actuator N81is operated by control unit M70from pins 23, 24, 25 and 26.The distribution actuator N80is operated by control unit M70from pins 19, 20, 21 and 22.An electronic governor M72activates the fan N85 on an earth command at different speeds: it receives an ignition-controlled power supply (INT/A) from the line protected by fuse F31 of the junction unit under the dashboard B2it receives a control unit input control signal from pin 10 and provides a feedback signal to pin 18 of M70.The fan N85receives a direct supply from the line protected by fuse F5 of the engine compartment junction unit B1Control unit M70 is connected, via the CAN line, from pins 12 and 13 to the Body Computer M1 and to node H44, exchanging the following signals: - speedometer signal; - screen washer engagement signal for activating the recirculation; - windows and sun roof closing command; - battery voltage signal; - heated rear windscreen on signal.
