Wiring diagram 2.
The contacts L and N are connected to phase and zero
respectively and the contacts L and LT are connected
with a jumper. The fan operates in active mode at a
pre-set speed, e.g. 30% of the maximum speed. As the
humidity level rises the fan goes to humidity control
mode with higher speed.
Wiring diagrams 3 and 4.
The contacts L and N are connected to phase and zero
respectively and the contact LT is connected to phase
through the external switch, light switch (wiring diagram
3) or momentary switch that is activated by opening a
door (wiring diagram 4).
The fan connected under the wiring diagram 3 or 4
operates in standby mode until humidity increase is
detected. In standby mode the fan is stopped or operates
at low speed that is adjustable from the control panel.
When the humidity sensor signals of high humidity level
the fan is switched to humidity control mode to extract
excessive humidity and odours and reverts to standby
mode in a while. The fan switches to active mode with
high speed after turning the external switch on.
FAN ADJUSTMENTS ( se page 6)
The fan is a ready-to-use product adjusted at the factory.
It is operable with no extra adjustments. Follow the
step-by-step instruction below for the Customer
adjustments. You can always reset the fan to the factory
settings if required.
Factory settings:
Standby mode speed - 0% of the maximum speed (off)
Active mode speed - 20% of the maximum speed
SMART mode speed - 70% of the maximum speed
HUMIDITY CONTROL MODE - SILENT
Fan post-running time - 5 min.
Turn-on delay before start - 0 min.
Humidity control mode timer operation - 5 min.
STEP-BY- STEP INSTRUCTION:
1. Adjust the standby mode speed. (se pict. 1-3)
By default the fan is off when humidity is within limits
and there are no signals from external switches and
motion sensor.
You can adjust permanent low speed in standby mode for
minimum airing. To activate airing function, press and
hold the button 24 HOURS and set the required speed
with buttons [+] and [-].
The optimum speed setting is from 0 to 30%
(default setting).
