DescriptionWhen required, the climate control systemECU automatically activates the cooling circuit and dehumidifiesthe air by operating the air conditioner compressor.The left-hand key on the climate controlpanel enables the operation of the air cooling circuit; when thebutton is pressed, the relevant LED comes on.The operation of the air refrigeration circuitis also enabled automatically (without pressing the button) whenthe ignition key is turned to the ON position if the temperatureof the air at the vents is below the temperature of the outsideair.This key enables the operation of the aircooling circuit; but the actual switching on of the compressor isexcluded at low external temperatures.Description The compressor can also be deactivated bythe 4-stage pressure switch or the engine management unit accordingto the engine management software, which is different for each engineversion ( 3232876seeDESCRIPTION AND OPERATION:1060DIESEL FUEL INJECTION ). The compressor supply circuit is controlledby a specific relay, located in the engine bay close to the battery.The relay contact line is protected by aspecial fuse and by the exclusion relay controlled by the ignition,located in the junction unit.The energizing line is protected by thefuse which protects other supplies controlled by the ignition.
Functional description The relay J20 controls the compressorengagement circuit. The relay receives a supply from the linecontrolled by the ignition (INT/A) for the relay R1 protectedby fuse F15 : both are housed in the junction unit B1 . The coil receives a supply controlled bythe ignition (15/54) from the line from fuse B25 up to 2/99or from fuse F4 of the additional fuse box B98A from2/99; the relay is thus energized by an earth signal coming fromthe engine management control unit M10 : in this way the airconditioning compressor L20 engagement electromagnet is operatedthrougha voltage of 12 V .

Follow these precautions.769On batteries with an opticam hydrometer,electrolyte level and battery charge status can be monitored qualitativelyby examining the indicator colour:a light, bright colour indicates low electrolytelevel: top up with distilled water;a dark colour without a green area in thecentre indicates that the electrolyte level is correct but chargeis low: recharge the battery;a dark colour with a green area in themiddle indicates that both electrolyte level and charge status arecorrect: no action is necessary. For more details 3238420See subassembly5530 CURRENT GENERATOR . 768Proceed as follows.Check the battery voltage without loadusing the test device recommended by the Service outlets (e.g. 'MICRO360').Depending on the voltage values measured,which define the state of charge of the battery, proceed as follows: If the voltage without load is less than12.10 V, replace the battery ( 32384295530B10battery - r+r ). If the voltage without load is over 12.10V but less than 12.50 V, recharge the battery ( 32384305530B14battery - recharge ). If the voltage without load is over 12.50V, the battery is efficient.If necessary, top up the electrolyte asfollows.Carefully remove the cap strip.Top up with distilled and deionized water,taking care not to allow electrolyte to splash out.768
