The ECO dMEV LC is suitable for wall
or ceiling mounting and can either ex-
tract directly to the outside or via an
individual ducting system (see Fig. 2).
Make a hole in the wall or ceiling of
diameter 105 mm.
If the unit is to be installed with indi-
vidual ducting, use a standard duct of
diameter 100 mm.

9
Remove the front grille (1) and the
protection cover (2).
The unit can be mounted on the wall
or ceiling using the 4 plastic plugs
and the screws provided.
Ensure that there are no obstructions
to the airflow and that the impeller
turns freely.
Introduce the mains cable through the
cable entry (5) and fix it to the wall.
Connect the electrical wiring as set
out below and then mount the protec-
tion cover and the front grille.
ELECTRICAL CONNECTION
The ECO dMEV LC is an extractor de-
signed for a single phase supply, with
voltage and frequency as indicated on
the rating plate of the unit. The units
are manufactured with double electri-
cal insulation (Class II) and therefore
they do not need an earth connection.
The electrical installation must inclu-
de a double pole switch with a contact
clearance of at least 3 mm.
The electrical cable must enter the
ECO dMEV LC through the cable en-
try (5).
Once the cable has been introduced
proceed using the electrical wiring
diagram applicable to the selected
model.
OPERATION
The ECO dMEV LC is an extractor fan
designed to operate continuously at
low speed (adjustable) with the facility
to be set to high speed (fixed) through
the following functions depending on
the version: an external switch live or
light switch (S, T and HT versions);
the humidity sensor (HT and HTP ver-
sions); the internal pull cord switch
(HTP version); or the PIR detector (DT
version).
The extractor can also be used for in-
termittent operation with adjustable
speed at installation.
In both cases the speed setting is
done when installing the extractor,
with the potentiometer (7) placed on
the electronic PCB (fig.1b).
Please commission the fan at 9l/s or
above to meet SAP requirements.
The selection between continuous
operation and intermittent operation
is done with the dip-switch 9:
Continuous operation: ON
Intermittent operation: OFF
ATTENTION: In intermittent opera-
tion, mount the backdraft shutter on
the fan outlet.
ECO DMEV S LC
1. Continuous operation only on tric-
kle setting (Fig. 3).
Once the air volume is set the fan
is connected to the mains and the
unit will operate continuously at
this air volume.
2. Continuous operation on trickle
with ability to boost at high speed.
The ECO dMEV S LC is connected to

10
an external switch or light switch.
When the switch is closed, the fan
runs at full speed until the switch
opens again (light off):
Fig.4a- Wiring diagram to boost the
fan with the light switch.
Fig.4b- Wiring diagram to boost
the fan with a separate switch
3. Intermittent operation: With dip-
switch 9 set to OFF the extractor
runs at the preset speed when the
switch is closed:
Fig.4a- Wiring diagram to switch
on the fan with the light switch.
Fig.4b- Wiring diagram to switch
on the fan with a separate switch.
Start-up timer function:
In this operation, the “start-up ti-
mer function” allows you to delay
the extractor start-up for a period
of 50 seconds. So that, for exam-
ple, the fan does not switch on if
the usage time of the bathroom is
less than 50s.
If you exceed the 50s, the fan swit-
ches on, and when the light swit-
ches off, runs the time set by the
timer.
This function is selected with the
dip- switch 8.
ECO DMEV T LC
This model is provided with an adjus-
table over-run timer.
The selection of the run on time is
done with the dip-switches 6 and 7:
setting between 1, 5, 15 and 30 mi-
nutes
Factory setting: 1 minute
1. Continuous operation: The timer
allows the fan to continue to ope-
rate in high speed for the selected
period after the switch has been
turned off.
Fig.4a- Wiring diagram to boost the
fan with the light switch.
Fig.4b- Wiring diagram to boost
the fan with a separate switch
2. Intermittent operation: The timer
allows the fan to continue to opera-
te for the selected period after the
switch has been turned off (fig.4a
and 4b).
Start-up timer function:
In this operation, the “start-up timer
function” allows the fan to delay the
start-up for a period of 50 seconds.
So that, for example, the fan does
not switch on if the usage time of the
bathroom is less than 50s.
If you exceed the 50s, the fan swit-
ches on, and when the light swit-
ches off, runs on for the time set by
the timer.
This function is selected with the
dip- switch 8.
ECO DMEV HT LC
Models provided with an electronic
humidity sensor which can be adjus-
ted from 60% to 90 % RH (relative

11
humidity) and with a timer, adjustable
between 1 and 30 minutes.
The selection of desired humidity le-
vel is done with the dip-switches 4
and 5: setting between 60, 70, 80 and
90 %RH:
The selection of the run on time is
done with the dip-switches 6 and 7: se-
tting between 1, 5, 15 and 30 minutes:
CONTINUOUS OPERATION
1. Automatic operation (fig.3): the
extractor is connected to the main
supply with only two wires. The
extractor operates continuously at
the setting trickle speed. When the
humidity level in the room is higher
than the set level the fan is boosted
to high speed. When the humidity
drops below the selected level and
after the selected period set on the
timer the fan automatically returns
to trickle.
2. Automatic operation with the faci-
lity to override the humidity sen-
sor and make the extractor run
in boost by means of an external
switch (fig.4a) or the light switch
(fig.4b), when the humidity level in
the room is lower than the selec-
ted level. In this case, the extrac-
tor operates in high speed for the
selected period set on the timer
after the light switch has been
switched off, and then goes back in
low speed unless the humidity level
exceeds the set point.
ATTENTION: When the humidity rate
is above the selected value, the auto-
matic option takes precedence over
the manual.
SPECIFIC RECOMMENDATIONS:
• If the humidity is always above 90%
RH, the fan will always run at full
speed.
• If the humidity in the room is always
less than 60%, the fan will only ope-
rate at trickle speed when running
in automatic operation.
If the fan never runs at boost:
• The setting of the humidity sensor
is at maximum. Change the setting
• The level of humidity in the room is
below 60% RH
If the fan always runs at boost
• The setting of the humidity sensor
is at minimum. Change the setting
• The level of humidity in the room is
above 90% RH
INTERMITTENT OPERATION
Automatic operation:
The extractor is connected to the main

12
supply with only two wires (fig.3). The
humidity sensor causes the extractor
to operate automatically when the
humidity level in the room is higher
than the set level. The extractor will
stop automatically when the humidity
drops below the selected level (-5% or
+10%) and after the selected period
set on the over-run timer.
“Interval” functions:
This function is useful when the ex-
tract fan is installed in very wet con-
ditions (near the sea) or the ambiance
exceeds the set level for a very long
time. To prevent the fan running for
hours without stopping, the “Interval”
function allows the fan to switch off
automatically one hour after it began
to run. The extractor keeps switched
off during the set time for interval
function. If the humidity level is still
above the set level when the time in-
terval is over, the extract fan switches
on again and runs for one hour.
When, on the contrary, the extract fan
never switches on because the hu-
midity level is always very low or it is
improperly installed (above heating
appliance, behind a door, in an area
with no air movement) putting the 1
dip- switch interval function to position
“ON”, the fan switches on automatica-
lly for 1 hour and then it keeps swit-
ched off during the set time for interval
function. This function causes the fan
to run whatever the humidity level.
To select this function put the dip-
switch 1 to position “ON”
To adjust the pre-set time for interval
function, use the dip-switches 2 and 3.
Automatic operation with external
switch to override the extractor:
The extractor is connected to the
main supply with three wires (fig.4a
y 4b).
Operation as previous “Automatic
operation”, with the facility to ove-
rride the humidity sensor by means
of the light switch when the humidity
level in the room is lower than the se-
lected level. In this case the extractor
continues to operate for the selected
period of time (over-run timer) after
the light switch has been switched off.
ATTENTION: When the humidity rate
is above the selected value, the auto-
matic option takes precedence over
the manual and the unit cannot then
be switched off using a switch.
Start-up timer function:
In this operation, the “start-up timer
function” allows you to delay the ex-
tractor start-up for a period of 50 se-
conds. So that, for example, the fan
does not switch on if the usage time
of the bathroom is less than 50s.
If you exceed the 50s, the fan switches
on, and when the light switches off,
runs the time set by the timer.
This function is selected with the dip-
switch 8.

ECO DMEV HTP LC
ECO dMEV LC version similar to HT
model, fitted with an internal pull
cord switch to operate the boost when
the humidity level is below the set
point (fig.5)
When switching off the internal pull
cord switch, the fan continues to
operate on boost for the time set by
the timer, then runs on trickle speed,
unless the humidity level exceeds the
set point.
ECO DMEV DT LC
Models provided with a PIR (passive
infra-red) detector (movement detec-
ted with a maximum distance of 4 me-
tres) and with an adjustable “run on”
timer (1 to 30 minutes).
The selection of the run on time is
done with the dip-switches 6 and 7:
setting between 1, 5, 15 and 30 mi-
nutes:
1. Continuous operation:
The extractor operates conti-
nuously at the setting trickle
speed. When the extractor detects
a movement the fan is boosted to
high speed during the selected pe-
riod set by the over-run timer and
then automatically returns to tric-
kle speed (fig.3).
2. Intermittent operation:
The unit starts automatically when
a movement is detected and the
unit continues to operate for the
selected period set on the over-run
timer (fig.3).
FACTORY SETTINGS:
Interval function: OFF
Interval time: 4h
Humidity sensor: 60%HR
Timer: 1 minute
Start-up timer function: OFF
Continuous operation: ON
MAINTENANCE
IMPORTANT: DISCONNECT FROM
THE MAINS SUPPLY BEFORE CARR-
YING OUT ANY MAINTENANCE
The ECO dMEV extract fan is supplied
with a plastic filter.
Performance depends on cleaning
frequency and thus we recommend
cleaning, minimum every two mon-
ths, in accordance with fig 1a.
The ECO dMEV extract fan must
always be operated with the filter fi-
tted.Using the extract fan without the
filter invalidates the warranty.
The external surface of the fan only
requires periodical cleaning using a
cloth lightly impregnated with a soft
detergent.
