Lancia THESIS. Service Manual - part 10

156

Should the system, as a result of

manual settings, no longer be able to
assure the selected temperature in
the various passenger compartment
areas, the selected temperature
value starts flashing to indicate the
system difficulty and the message
AUTO automatically turns off.

To restore the system automatic

control at any moment after one or
more manual setting, press button
AUTO.

MONO button
(set temperature and air distrib-
ution alignment) (16 fig. 121)

Press the MONO button to auto-

matically align the front/back-seat
passenger’s side temperature and air
distribution to the temperature air
distribution on driver’s side.
Consequently, the temperature and
air distribution in the two areas can
be set simply by turning the knob on
driver’s side. This function is provided
to facilitate adjusting the temperature
in the passenger compartment when
only the driver is present.

To restore separate temperature and

air distribution control in the two
passenger compartment areas, rotate
knob 8 (fig. 121) or 1 (fig. 122) to set
up temperature in the front/back-
seat passengers’ area or press again
button MONO 16 (fig. 121) when the
button led is on.

REAR button (rear control panel
activation) (11 fig. 121)

Press the REAR button to switch

the rear control panel on and to cut
out the front control panel. As a
result, back-seat passengers can
select temperature, air distribution
and fan speed according to their
needs.

When rear controls are activated,

the led on button REAR is on.

IMPORTANT The fan speed can

be adjusted manually also by the
rear control panel, when activated,
but it is the same one for the whole
passenger compartment. 

The climate control system can be

deactivated also by the rear control
panel, when operating: press repeat-
edly or keep pressed button 7 (fig.
122) until all the fan bars on the dis-
play turn off and message OFF is
displayed.

To exclude the rear control panel,

press again button REAR; the but-
ton led turns off and the front-seat
passenger’s controls are operating
again.

Air recirculation on/off button 
(3 fig. 121)

The air recirculation function is

controlled according to three strate-
gies:

– automatic operation (button left

led on);

– forced ventilation on (recircula-

tion always on), the right led on the
button will come on;

– forced deactivation off (recircula-

tion always off, air taken from the
outside), both leds on the button will
go off.

The three conditions are obtained

by pressing the air recirculation but-
ton 3 in sequence.

When the air recirculation function

is automatically controlled by the
system, the left led on the air recir-
culation button is turned on, while
the right led is on or off according to
the actual recirculation conditions
(on or off).

During automatic operation, the

recirculation function is automati-
cally switched on when the pollution
sensor detects the presence of pollut-
ed air, e.g. in cities, queues, tunnels
and during windscreen wiper opera-
tion (due to the characteristic smell
of alcohol). 

In addition, if the compressor is on

and the outside temperature is over
5 °C, to prevent air polluted by
exhaust gases getting inside the pas-
senger compartment during stops,
the system stops air recirculation
when the car speed is lower than 6
km/h. When the car speed returns
over 12 km/h, the system restores
the previous conditions.

After using the air recirculation

function for a long time (over 15
consecutive minutes), the system
automatically stops it for safety rea-
sons, thus letting air be changed.

When air recirculation manual

control is set (button left led off),
message FULL on the display is off.

157

158

IMPORTANT Air at a temperature

lower than that of the outside air
cannot be let in to the passenger
compartment when the compressor
is off. Furthermore, in particular
environmental conditions, the win-
dows could mist up fast because the
air is no longer dehumidified.

The setting will be stored when the

engine is stopped. Either press 

√

button again or press the AUTO but-
ton to reset automatic control of the
compressor (in the latter case, the
manual settings will be cancelled).
The led on the 

√ button will go out.

IMPORTANT The air recircula-

tion function will allow, according to
the system operation (i.e. heating or
cooling) to reach the required condi-
tions faster. We recommend not
turning on this function on rainy
and/or cold days as this will consid-
erably increase window misting,
especially if the climate control sys-
tem is off.

In particular climate

conditions (e.g. low out-
side temperature or high

humidity) and with the inside air
recirculation automatic control
on, windows could start misting
up. In this case, press the air
recirculation button and set it to
forced open position (both button
leds off), and increase air flow to
the windscreen, if required.

Climate control system
compressor off button (7 fig. 121)

Press the 

√ button, when the but-

ton led is on, to switch the air condi-
tioner compressor off. The led will
go off. By pressing again the button
when the led is off, the system auto-
matic control of the compressor acti-
vation is restored; this situation is
indicated by button led lighting up.

When the air conditioner compres-

sor is off, if the system is no longer
able to keep the requested tempera-
ture, the message FULL AUTO on
the display turns off and the system
deactivates air recirculation to pre-
vent window misting up. Instead, if
the system is still able to maintain
the requested temperature, the mes-
sage FULL on the display will stay
on.

159

The air let into the passenger com-

partment cannot be cooled when the
compressor is off. Consequently:

– if the outside temperature is

lower than the set temperature, the
system works normally and can
reach and maintain the set tempera-
ture also when the compressor is off;

– if the outside temperature is

higher than the set temperature, the
system cannot reach the required
temperature. This will be signalled
by flashing the external temperature
value on the display. 

When the compressor is off, it is

possible to reset manually the fan
speed; on the contrary, when the
compressor is on and the engine is
running, manual ventilation cannot
be lower than the bar indicated on
the display. 

Button for fast windscreen
demisting/defrosting (15 fig. 121)

Press this button: the climate con-

trol system will automatically switch
on all the functions required for fast
windscreen and side window demist-
ing/defrosting, that is:

– climate control system compres-

sor on;

– air recirculation off (if on);

– maximum air temperature (HI)

on both displays;

– fan speed according to engine

coolant temperature in order to limit
letting cold air into the passenger
compartment for demisting the win-
dows;

– air flow directed to the wind-

screen and front side window vents; 

– heated rear window, external

rearview mirror and windscreen noz-
zle resistances on.

The fast windscreen demisting/

defrosting function stays on for
approx. 3 minutes after the engine
coolant temperature exceeds 50 °C
(petrol versions) or 35 °C (diesel
versions).

When the fast demisting/defrosting

function is on, the led on the related
button and that on the heated rear
window button are lighted, while
both leds on the air recirculation
button and that on button 

√ turn

off. Message FULL AUTO on the
display will turn off.

Only the fan speed can be adjusted

and the heated rear window can be
switched off when the fast demist-
ing/defrosting function is on. 

Press the fast demisting/defrosting

button again or air recirculation
button or compressor off button to
switch the fast demisting/defrosting
function off and reset the previous
system operation conditions as well
as the last set function. 

160

Button for demisting/defrosting
the heated rear window and
external rearview mirrors 
(12 fig. 121)

Press this button to switch on the

heated rear window and external
rearview mirror demisting/defrost-
ing function. The led on the button
will come on.

The device will be automatically

switched off after ten minutes. Press
the button again or stop the engine
to switch the function off. It will not
start up automatically when the
engine is started again.

IMPORTANT Do not apply stick-

ers on the electrical filaments of the
heated rear window inside part to
prevent damage.

OFF button (system off) 

The switch the climate control sys-

tem off, keep pressed for at least two
seconds the fan button 14 (fig. 121)
on the front control panel or button
7 (fig. 122) on the rear control
panel; all the fan bars on the display
turn off and the message OFF will
be displayed. The right led on the air
recirculation button will come on.

The climate control system condi-

tions when the system is off are:

– air recirculation and compressor

off button leds off;

– set temperature displays off;

– air recirculation on, thus isolating

the passenger compartment;

– climate control system compres-

sor off;

– fan off.
The heated rear window can be

switched on and off normally when
the system is off.

IMPORTANT The windows may

mist up fast when the climate con-
trol system is off and in certain envi-
ronmental conditions.

The climate control system elec-

tronic control unit stores the system
settings made before the system was
switched off and restores them as
soon as a button is pressed (with the
exception of the heated rear window
button). The function which the
button corresponds to will be
switched on, if it was off when the
system was switched off. It will be
kept if, on the other hand, it was on
when the system was switched off.

Press the AUTO button to switch

the climate control system back on
and ensure a totally automatic con-
trol.

161

ACTIVE CARBON
DUST/POLLEN FILTER

The filter has the specific capacity

of combining a mechanical air
cleaning action and an electrostatic
effect so that the air let into the pas-
senger compartment is purified from
particles such as dust, pollen, etc.

In addition to this function, the fil-

ter efficaciously reduces the concen-
tration of pollutants thanks to a
layer of active carbon inside the fil-
ter.

The filtering action is carried out

on the air let in from outside (recir-
culation off). 

Have the filter checked at least

once a year at a Lancia
Dealership, ideally at the begin-
ning of the summer.

The efficacy of the cli-

mate control system may
be considerably reduced

if the filter is not replaced.

Fan actuation is automatic and air

distribution corresponds to the latest
setting made before switching the
car off.

This function is useful especially on

summer days since it greatly reduces
the temperature inside the passenger
compartment as well as the duration
of the cooling cycle after car start-
up, thus avoiding the accumulation
of warm air in the air conditioning
unit lines. 

IMPORTANT Best operation of

the fan when the car is parked is
obtained by closing completely the
windows and sunroof. Furthermore,
to check operation at first speed of
the fan, disengage air vents and set
air distribution from central dash-
board vents only before leaving the
car.

You should have the filter checked

and if required replaced more fre-
quently if the car is mainly used in
polluted or dusty areas.

VENTILATION DURING A STOP

In versions with sunroof, the roof

top features 21 photovoltaic cells
supplying a maximum power of 24
W to supply the climate control sys-
tem fan when the car is parked with
the roof closed or horizontally pivot-
ing.

162

SUPPLEMENTARY
HEATER
(where provided)

The supplementary heater can

work with the engine off or on and it
allows the following: 

– to heat the engine coolant before

start up

– to reduce the engine warming up

time after cold starting

– to warm up the passenger com-

partment before departure

– to remove ice or condensate from

the windows.

Using the heater in winter has the

following advantages:

– to reduce engine wear

– to reduce polluting emissions

– to improve comfort during dri-

ving and stops

– to improve safety.

The supplementary heater function

is useful to integrate the engine
coolant warming up during driving
in order to reach and keep the opti-
mal working temperature of the pas-
senger compartment heater in the
quickest way, especially if the cli-
mate is extremely cold.

The system is composed of:

– a heating unit

– an electric pump for the engine

coolant circulation

– an exhaust pipe with muffler

– an electric pump metering the

fuels

– a fuel delivery pipe

– a sensor for outside air tempera-

ture.

The system is connected to the car

through the engine cooling system,
the fuel system and the electric sys-
tem. The coolant coming out from
the engine is conveyed to the heater
and made flow in the circuit by an
electric pump. The heater burner is
supplied with the car fuel taken
directly from the tank by means of
an electric pulse pump and then
conveyed to the appropriate system
pipe. The heater control unit sup-
plies directly both electric pumps
(fuel and coolant), activates and
checks the heater functions.

The supplementary heating system

works both with the engine running
and the engine stationary. These two
conditions determine the type of sys-
tem operating mode:

– when the engine is stationary the

supplementary heater can work in
“programmable heater” or “parked-
car heater” mode;

163

– when the engine is running the

system works only in “supplemen-
tary heater” mode. 

Regardless of the operating mode,

the start up procedure for the sup-
plementary heater, once it has been
activated, is the following:

1 - Fan activation for comburant

air, for at least 30 seconds, to venti-
late and oxygenate the combustion
chamber. The fan speed is progres-
sively increased until the average
operating value is reached.

2 - After about 30 seconds, the

heater control unit activates the
electric pump metering the fuel and
the comburant air fan is deactivated
for at least 3 seconds, in order to
facilitate fuel burning. A spark plug
starts combustion inside the heater.

3 - At this point, there is a com-

bustion stabilizing phase which lasts
around 15 seconds, during which
the fan speed is kept at average
level.

4 - In the following 50 seconds the

control unit makes the fan reach
nearly its highest speed.

5 - Once combustion has stabilized,

the heater control unit deactivates
the plug and the fan reaches its
maximum speed.

6 - From now on the plug is used

by the system as a combustion and
flame sensor.

7 - Regardless of the operating

mode, the heater extinction proce-
dure is always based on the combus-
tion chamber ventilation for about
30 seconds, in order to eliminate
completely any combustion remain-
der.

IMPORTANT After switching the

system off, both automatically or
manually, it can be switched on
again (ON) only approx. 3 minutes
after or when the CONNECT mes-
sage “COOLING DOWN” disap-
pears from the display. 

IMPORTANT Although in a lesser

quantity the heater burns fuel as the
engine. Therefore, to prevent poi-
soning and suffocation the supple-
mentary heater shall never be turned
on, even temporarily, in confined
areas like garages and workshops
not equipped with exhaust fans.

IMPORTANT The heater must

always be turned off during refu-
elling and at filling stations to pre-
vent the risk of explosions.

IMPORTANT Do not park the car

over flammable materials like paper,
grass or dry leaves: risk of fire.

OPERATION WITH ENGINE
STATIONARY

“Programmable heater” mode

With this operating mode, the sys-

tem heats the engine coolant and the
passenger compartment before
starting the engine, it keeps air recir-
culation closed and activates air dis-
tribution to the windscreen and the
floor by operating the passenger
compartment fan.

164

This function can be activated with

the CONNECT (from the main
SETUP screen) or with the remote
control.

The system works with this mode on

if the following conditions are present

– outside temperature lower than 20

°C

– coolant temperature lower than 50

°C

– ignition key at STOP or removed

– car battery charged

– fuel not in reserve.

When this mode is on, the heater is

deactivated when one of the following
conditions occur:

– end of planned working time

– OFF signal from the remote con-

trol

– manual shutdown by the user

through CONNECT

– ignition key at MAR

– partial battery rundown

– fuel in reserve

– malfunction detected by the heater

control unit.

Timed heater activation/
deactivation through CONNECT

Timed heater activation and deacti-

vation can be set through the CON-
NECT. Select and confirm “Heater”
on the main SETUP screen to display
the parked-car heater settings.

Settings available are the following:

– Operate now

– Timer 1

– Timer 2.

To activate/deactivate the required

function, select and confirm it with
the CONNECT right knob.

“Operate now”

The option “Operate now” enables

to warm the passenger compartment
with the engine stopped and warm
and the ignition key to MAR, using
the engine coolant, heater coolant cir-
culation pump, automatic air distrib-
ution control (if not set manually) and
closing air recirculation. The timer
cannot be programmed when this
function is on.

To guarantee the required comfort,

this function shall be mainly activated
when coolant is hot enough. When
coolant temperature is lower than 50
°C the control unit starts the heater,
and when temperature is over 70 °C,
the control unit turns the heater off
and lets only the coolant circulation
pump keep on working.

165

The “parked-car heater” mode is

automatically deactivated when one
of the following conditions takes
place:

– engine started

– limit time (around 30 minutes) of

heater and/or coolant pump func-
tioning overcome

– turn off requested by the user

through the CONNECT

– malfunction detected by the heater

control unit

– partial battery run-down or alter-

nator fault.

“Timer 1” and “Timer 2”

The “Timer” options shall be used

to programme two heater daily cycles;
for each cycle enter the time of acti-
vation and the length of operation
both with 5 minute intervals. 

Each cycle cannot last more than 60

minutes. The default operation is 15
minutes. The timer works regardless
of the ignition key position.

During heater operation, messages

referred to the following conditions
are shown on CONNECT display:

– fuel level in reserve (continue any-

way?)

– fuel level in reserve. Parked-car

heater has been switched off

– parked-car heater not operating

because of cooling down

– parked-car heater not operating

because external temperature is
higher than 20 °C

– parked-car heater not operating

because motor is on

– parked-car heater has been

switched off because of low voltage.

IMPORTANT For safety reasons,

the timer must be programmed/con-
firmed at any activation and con-
firmed not later than 24 hours since
programming. In addition, the user
must confirm every time the timer ac-
tivation. The timer does not automat-
ically correct standard time.

The timer can be in one of the fol-

lowing conditions:

– off: in this condition the timer is

programmable and parameters can be
loaded or adjusted. Loaded parame-
ters should be valued and approved
by CONNECT

– on: activated parameters approved

by CONNECT are stored in the mem-
ory. The user confirms the set cycle
waiting for the programmed activa-
tion moment which is indicated on the
CONNECT display

– active: the heater is working in

“programmable heater” mode con-
trolled by the timer present on the
CONNECT display. When the timer
is activated, the CONNECT records
the system conditions

166

– stationary: with the “programma-

ble heater” mode controlled by the
timer, the system conditions are con-
trolled by CONNECT.

The timer is automatically deacti-

vated if:

– the “programmable heater” mode

function is stopped by CONNECT if,
at the timer start, the “programmable
heater” mode is activated with the re-
mote control

– if the user manually activates the

heater during the timer operation

– if the timer is activated within 3

minutes after the previous heater
shutdown

– if the user manually deactivates

the timer

– if the fuel level in the tank is low

when the timer is activated. This con-
dition is indicated with a message
coming from the system and the user
must confirm activation. If the user
does not confirm activation, the timer
is deactivated. The fuel level is indi-
cated by the CONNECT; if this infor-
mation is not available, it is taken into
consideration the last record before
stopping the engine

– if the timer is activated when the

heater operated by the remote control
is activated.

IMPORTANT If the heater is in

prompt operating mode, the timer is
automatically stopped at the moment
of activation. Parameters set with the
timer are stored in the memory. If the
timer has been deactivated or
stopped, it should be manually reac-
tivated by the user.

HEATER ACTIVATION/
DEACTIVATION WITH THE
REMOTE CONTROL (fig. 123)

Activation/deactivation of the heater

can be operated with remote control
A.

The activation signal is issued by the

remote control with a range of around
600 meters and picked up by a spe-
cific antenna placed on the car, then
it is transmitted to the supplementary
heater receiver and sent to CON-
NECT.

IMPORTANT The maximum re-

mote control range is reached on open
land, while it is reduced in the pres-
ence of buildings.

fig. 123

L0A0263b

167

This control is accepted by CON-

NECT only if:

– outside temperature lower than 20

°C

– coolant temperature lower than 50

°C

– the ignition key is at STOP or re-

moved

– car battery charged

– sufficient fuel level

– the timer is deactivated.

Switching the heater on

To switch the heater on, press the

remote control button ON for 1 or 2
seconds, while keeping the antenna in
vertical position; the positive or un-
successful activation is indicated by
the remote control red led B in the fol-
lowing way:

– the led turns on for about 2 sec-

onds = the signal has been correctly
received and the heater has been ac-
tivated

– the led flashes for about 2 seconds

= the signal has not been received.

In the latter case you are advised to

move before trying to activate it by
pressing again the ON button.

After the confirmation activation,

the led B will flash every 2 seconds for
the whole operation cycle duration.

IMPORTANT If led B turns on with

green colour, press twice both remote
control buttons ON and OFF within 1
second to set the red colour. 

Activation length

When pressing the remote control

button ON the last recorded activa-
tion length is always activated.

To see the recorded length, press at

the same time for three consecutive
times within 1 second, the remote
control buttons ON and OFF, count
the number of flashes of led B then
compare them to those shown in the
table below, including also the first
flash appearing the third time you
press the buttons. 

Default activation length is 30 min-

utes but it can be changed through
the following procedure:

– press at the same time for three

consecutive times within 1 second, the
remote control buttons ON and OFF

– count the number of flashes of led

B including also the first flash ap-
pearing the third time you press but-
tons ON and OFF

– press OFF to set the length suc-

cessive to the set one (press OFF for
several times to set the required
length in sequence)

– wait for about 10 seconds for timer

storing.

168

- the led comes on for about 2 sec-

onds = the signal has been received
correctly and the heater has been de-
activated

- the led flashes for about 2 seconds

= the signal has not been received.

In the latter case you are advised to

move before trying to deactivate it by
pressing again the OFF button.

Checking and replacing the
batteries

To check the battery charge, press

ON or OFF: if after about 5 seconds
led B comes on with orange colour it
means that the batteries are nearly
down and that they shall be replaced.

The batteries must be replaced with

new ones of the same type, available
at the usual sellers.

Replacing the batteries

Keep the ON and OFF buttons

pressed for about 10 seconds, until led
B turns off, to reset the 30 minutes
standard operation length.

Switching the heater off

To turn the heater off, press the re-

mote control button OFF for 1 or 2
seconds, while keeping the antenna in
vertical position; the positive or un-
successful deactivation is indicate by

“Supplementary heater” mode

This operating mode integrates the

engine coolant warming up, immedi-
ately after start up or during driving,
to reach and keep the optimal work-
ing temperature of the engine and the
passenger compartment heater in the
quickest way.

This mode is activated automatically

by the climate control unit when the
following conditions occur at the same
time:

– ignition key at MAR

– engine running

– coolant temperature lower than 30

°C

– the climate control unit detects

(according to sensor detected temper-
atures) that fast passenger compart-
ment warming is required.

This mode is automatically deacti-

vated when one of the following con-
ditions occurs:

– coolant temperature higher than

70 °C

– the heater control unit detects a

fault in the supplementary heater

– engine off.

The batteries must be replaced with

new ones of the same type, available
at the usual sellers.

To replace batteries:

– remove the remote control cover

by pushing it in the arrow direction
indicated on the cover

– remove exhausted batteries and

take note of their position

– fit the new batteries with pole (+)

towards the remote control antenna

– fit down the cover.
