EcoAIR HLC
Models provided with an electronic
humidistat which can be adjusted
from 60% to 90 % RH (relative humi-
dity) and with a timer, adjustable be-
tween 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:
setting between 1, 5, 15 and 30 mi-
nutes.
CONTINUOUS OPERATION
1. Automatic operation (fi g.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 hygrostat and
makes the extractor to run in boost
by means of an external switch
(fi g.4a) or the light switch (fi g.4b),
when the humidity level in the
room is lower than the selected le-
vel. In this case, the extractor ope-
rates in high speed for the selected
period set on the timer after the
switch light has been switched off,
and then goes back in low speed
unless the humidity level exceeds
the set point.
ATENTION: When the humidity rate
is above the selected value, the auto-
matic option takes precedence over
the manual.
Specifi c 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-
rates at trickle speed when running
in automatic operation.
If the fan never runs at boost:
• The setting of the humidistat is to
the 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 humidistat is to
the minimum. Change the setting
• The level of humidity in the room is
above 90% RH.
