Electric stationary air conditioning system
Information about the stationary air condi‐
tioning system
The stationary air conditioning system cools the
interior air according to the set temperature inde‐
pendently of the engine.
You operate the stationary air conditioning sys‐
tem via the
Climate control
menu in the multime‐
dia system (
/
page 108) or via the bed/berth
switch panel (
/
page 113). You can switch the
stationary air conditioning system on or off man‐
ually (immediate cooling mode) or define switch-
on times.
The operating time of the stationary air condition‐
ing system depends on the following factors:
R
Outside temperature and sunlight
R
Set vehicle interior temperature
R
State of charge and age of the batteries
R
Operation of other electrical consumers
R
Driving cycle
The stationary air conditioning system can oper‐
ate for up to eight hours. As the batteries age,
the operating time of the stationary air condition‐
ing system will reduce. The stationary air condi‐
tioning system is supplied with voltage not from
separate, auxiliary batteries, but rather exclu‐
sively from the batteries belonging to the vehicle.
In order to maintain the ability of the vehicle to
start and the service life of the batteries, the
power output of the stationary air conditioning
system will automatically be reduced in incre‐
ments or the system switched off. After it has
switched off automatically, the stationary air con‐
ditioning system can be switched on again only
after a journey time that is sufficient to charge
the batteries. In short-distance driving, the charg‐
ing phases are too short to charge the batteries
sufficiently to operate the stationary air condi‐
tioning system. In this case, the stationary air
conditioning system can be used only to a limited
extent. If the auxiliary climate control cannot be
switched on due to an insufficient battery charge,
an event window stating this will appear on the
multimedia system display.
Observe the instructions on care and mainte‐
nance of the batteries (

page 329).

When you are driving, cool the cab to a pleas‐
ant temperature in advance. When outside
temperatures are very high, minimise the use
of other electrical consumers in the cab
before and during operation of the stationary
air conditioning system.
If you shut the window curtains and move the
seat backrests forwards, thermal radiation will be
limited and the stationary air conditioning system
made more effective.
The control for the stationary air conditioning
system will feed fresh air into the cooled interior
air as needed. This means that you do not have to
open the windows during an overnight stop or
during longer idle times. After it is switched on,
the blower of the stationary air conditioning sys‐
tem will operate in automatic mode, which you
can switch off if necessary. In automatic mode,
the stationary air conditioning system will regu‐
late the airflow automatically. If the temperature
of the outside air is sufficient for cooling the inte‐
rior air in automatic mode, the stationary air con‐
ditioning system will switch to fresh air mode.
This will extend the operating time, as it will
spare the batteries.
If you switch the stationary air conditioning sys‐
tem on manually or via the switch-on time, the
auxiliary heating (
/
page 110) and the residual
heat utilisation (
/
page 110) will automatically
be switched off.
