humidity sensor (HT and HTP
versions); the internal pull cord switch
(HTP version); or the PIR detector (DT
version).
The extractor can also be used for
intermittent 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.1).
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 operation,
mount the backdraft shutter on the fan
outlet.
ECO dMEV S LC
1. Continuous operation only on trickle
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
an external switch or light switch.
When the switch is closed, the fan
runs at full speed until the switch
opens again (light off):

fan with the light switch.

fan with a separate switch
3. Intermittent operation: With dip-switch
9 set to OFF the extractor runs at the
pre-set speed when the switch is
closed:

the fan with the light switch.

the fan with a separate switch.
Start-up timer function:
In this operation, the “start-up timer
function” allows you to delay the
extractor 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
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 T LC
This model is provided with an
adjustable 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 minutes
Factory setting: 1 minute
1. Continuous operation: The timer
allows the fan to continue to operate in
high speed for the selected period
after the switch has been turned off.

fan with the light switch.

fan with a separate switch
2. Intermittent operation: The timer
allows the fan to continue to operate
for the selected period after the switch
has been turned off (fig.4a and 4b).
