EcoAIR SLC
1. Continuous operation only on tric-
kle setting (Fig. 3).
Once the air volume 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 EcoAIR SLC 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):

the fan with the light switch.
Fig.4b - Wiring diagram to boost
the fan with a separate switch.
3. Intermittent operation: The extrac-
tor runs at the pre-set speed when
the switch is closed:

on the fan with the light switch.

on the fan with a separate switch.
Start-up timer function:
In this operation, the "start-up ti-
mer function" allows 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 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.

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.

2. Intermittent operation: The timer
allows the fan to continue to opera-
te for the selected period after the
switch has been turned off (fi g.4a

Start-up timer function:
In this operation, the "start-up timer
function" allows to delay the extrac-
tor 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 swit-
ches on, and when the light switches
off, runs the time set by the timer.
