The ECO dMEV may also operate at high
speed that is activated by: an external
switch live or light switch (
S, T and HT
versions
) an integral humidity sensor
(
HT and HTP versions
) or an internal
pull cord switch (
HTP version
).
ECO dMEV S
The ECO dMEV S can operate in two
modes:
1. Continuous operation on trickle setting
only (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
the ability to boost on high speed.
The ECO dMEV is connected to an
external switch or light switch.
When the switch is pressed, the fan
operates on full speed (not constant)
until the switch is turned off (light off):

with the light switch.

with a separate switch
ECO dMEV T
This model is provided with an adjustable
over-run timer. The timer allows the fan
to continue to operate for the selected
period after the switch has been turned
off (fig.5).
Fig.4 shows how to connect the fan with
timer through using the same switch as
the lighting circuit to allow the fan to be
boosted.
To set the timer, turn the potentiometer
“P2”
on the printed circuit board as (fig.
7).
- Manufacture setting:1 minute
- To reduce the "run on" time, turn
anticlockwise (min: 1 minute)
- To increase the "run on" time, turn
clockwise (max: 30 minutes).
ECO dMEV HT
Models provided with an electronic
humidity sensor which can be adjusted
from 60% to 90 % RH (relative humidity)
and with a timer, adjustable between 1
and 30 minutes.
Operation
Case
1: Automatic operation (fig.3)
In automatic operation, the extract fan
operates continuously on the trickle
setting speed. When the humidity level in
the room is higher than the set level the
fan will boost 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.
Case
2: Automatic operation as in case 1
with the facility to override the humidity
sensor by means of an external switch
(fig.5) or light switch (fig.4), when the
humidity level in the room is lower than
the selected level. In this case, the
extract fan continues to operate for the
selected period set on the timer after the
light switch has been turned off.
