with a separate switch
ECO DMEV T
This model is provided with an adjus-
table over-run timer. The timer allows
the fan to continue to operate for the
selected period after the switch has
been turned off (fi g.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 potentiom-
eter
“P2” on the printed circuit board
as (fi g. 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 ad-
justed from 60% to 90 % RH (relative
humidity) and with a timer, adjustable
between 1 and 30 minutes.
OPERATION
Case 1: Automatic operation (fi g.3). In
automatic operation, the extract fan
operates continuously on the trickle
setting speed. When the humidity lev-
el 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 auto-
matically 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 (fi g.5) or light switch
(fi g.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.
ATTENTION: When the humidity rate
is above the selected value, the auto-
matic option takes precedence over
the manual.
SETTINGS
The settings at manufacture are 60%HR
for humidity and 1 minute for timer.
The desired humidity level is select-
ed by means of a potentiometer “
P3 ”
positioned on the printed circuit board
(fi g.8).
• To increase the relative humidity
sensitivity turn anticlockwise (min.
60%).
• To reduce the relative humidity sen-
sitivity turn clockwise (max. 90%).
To set the timer, turn the potentiom-
eter “
P2 ” on the printed circuit board
(fi g.8):
• To reduce the “run on” time, turn
anticlockwise (min. 1 minute).
• To increase the “run on” time, turn
clockwise (max: 30 minutes).
