7.4 Air conditioning modes

Air conditioning modes of mechanical models The roof air conditioner has the following air conditioning modes: Air conditioning mode Displayed symbol Description Cooling You specify the temperature and fan settings, and the roof air conditioner cools the interior to this temperature. Ventilation You specify the fan settings, and the roof air conditioner circulates air without heat- ing or cooling. Air conditioning modes of fixed-speed and inverter models Air conditioning mode Displayed symbol Description Automatic You specify the temperature, and the roof air conditioner brings the interior to this temperature by heating or cooling and by controlling the necessary fan speed. Cooling You specify the temperature and fan settings, and the roof air conditioner cools the interior to this temperature. Heating You specify the temperature and fan settings, and the roof air conditioner heats the interior to this temperature. The fan will only start after 2min (on Low speed) and then after around 5min will go to the set fan speed (after the evaporator reaches temperature). Only available for models with heating mode. Ventilation You specify the fan settings, and the roof air conditioner circulates air without heat- ing or cooling. Dehumidifying The roof air conditioner removes moisture from the air without heating or cooling the interior thus decreasing the relative air humidity. Air purifier The roof air conditioner ionizes the air, thus collecting dust and particles including to viruses and bacteria out of the air. Only available for models with air purification mode.

7.5 Additional functions

These additional functions are not available for mechanical models. Additional func- tion Display message Description The roof air conditioner is switched on at the specified time. The roof air conditioner is switched off at the specified time. Timer The roof air conditioner is switched on and off at the specified times. 10Dometic FJXEN Additional func- tion Display message Description Sleep The sleep function reduces the fan speed and the compressor speed to reduce the noise levels for comfortable sleeping. I Feel The remote control measures the room temperature and transmits this measurement to the roof air conditioner every 10min . The roof air condi- tioner adapts the target value to this measurement. So start Only for models with so start mode. The peak current that the compressor start produces is reduced by the so start function. If a generator is used as power supply, the generator will not be overloaded. 8 Before initial use Inspection before starting up Before switching on the roof air conditioner, observe the following: Check whether the supply voltage and frequency correspond to the values specified in Technical data on page25. Ensure that both the air intake openings and the air nozzles are free. All ventilation grilles must always be kept free to ensure that the roof air conditioner is able to operate at maximum capacity. Prepare the remote control Only for models with remote control Insert the batteries (Replacing the remote control batteries on page16). Set the time Only for models with timer mode. Set the current time (Setting the current time on page14). 9 Operation

9.1 Tips for enhanced performance

To optimize the performance of the roof air conditioner, observe the following tips:

• Improve the heat insulation of your vehicle by sealing gaps and hanging reflective blinds or curtains on your windows.

• Select an appropriate temperature and fan speed.

• Align the air nozzles sensibly.

• Ensure that the air nozzles and air intake openings are not covered by cloths, paper, or other objects. Only for mechanical models

• If the vehicle has been under direct sunlight for a long time, operate the roof air conditioner in the Ventilation ( ) mode with the windows open for a while before switching to the Cooling ( ) mode.

• Avoid opening doors and windows for as long as possible in the Cooling ( ) mode.

9.2 Basic notes on operation

The mechanical models have three operating modes: 11ENDometic FJX Operating mode Description Off The roof air conditioner is switched off. Cooling The roof air conditioner cools the interior. Ventilation The roof air conditioner circulates air without cooling. The fixed-speed and inverter models have two operating modes: Operating mode Description Standby The roof air conditioner is ready for operation and can be switched on with the remote control. The ambient lights are available. The remote control is also in standby, but you can switch the remote control on independently from the roof air conditioner. On The roof air conditioner is conditioning the air in the interior.

9.3 Mechanical models

The given information in this chapter applies only to the FJX4233M roof air conditioners.
