Installation

A jumper behind the motor cover can be accessed
during installation and allows one of two minimum
speed settings to be selected: 5 l/s (18 m³/hr) or 10 l/s
(36 m³/hr). (Fig. 2,3)
N.B.
Other settings that differ from the ones mentioned in
this booklet must not be used as they might prevent
the appliance from operating properly.
Timer setting (Vort Notus T-HCS, fig.4)
The relative humidity sensor threshold is factory set at
60%.This setting can however be modified by the
installer to 4 levels: 60%, 70%, 80% and 90% (fig. 4).
Wall/ceiling mounting (fig.5-24)
The flange, safety grille and possibly the front panel
allow units to be wall (with ducted or unducted outflow)
or ceiling mounted.
Typical Applications
Fig. 25-26
ATTENTION
If the appliance is fitted in such a way that part of it is
against a wall and part against a protruding tiled
surface, spacers need to be fitted to compensate for
any difference in level and thus ensure that the unit
operates correctly.

Operating Principles

Model VORT NOTUS: this model offers users a choice
of two extraction speeds. The first speed is designed to
ensure a steady, continuous exchange of air in the
environment where it is positioned while the second
speed can be manually selected by the user to provide
additional extraction capacity as required.
Model VORT NOTUS T-HCS: both speed settings are
automatically maintained by the appliance and speed
varies with load conditions. Any increase in motor
speed, within a wide range of back-pressure
parameters, is accompanied by an increase in the
noise the fan makes. This is absolutely normal and
shows that the appliance is working properly. The
appliance has an electronic circuit board with a
humidity sensor and timer that allow a previously set
minimum speed setting to be switched automatically to
maximum speed depending upon the type of electrical
connection :
• the percentage of relative humidity present in the
atmosphere exceeds the pre-set value.
• If the relative humidity is lower than the sensor pre -
set value, the fan may be switched to high speed
manually by operating a separately wired switch
(which could be a room light switch). When the switch
is switched off again the appliance will continue to
operate at maximum speed for the pre - set time
(settings from 3 to 20 minutes can be selected during
installation) and will then go back to operating at
minimum speed.
Connecting the appliance to a switch other than one
that controls the indicator light allows direct control of
maximum/minimum speeds as on the Vort Notus
model.
