DESCRIPTION OF FUNCTIONS
• Automatic moisture detection system
Vent-Axia Lo-Carbon iQ is equipped with fully automatic
humidity control, which means the fan learns to run only
when it can make a difference.
• Timer
Selectable delay time – 5, 15 or 30 minutes.
• Speed control
The integral speed control allows you to adjust the noise
level and capacity to meet your needs.
• Continuous Trickle operation
Leave the fan running continuously if you need basic
ventilation in the home. This also eliminates the risk of
draughts in case of wall mounting.
• Airing function
If the fan has been inactive for 26 hours, an airing
programme will run for 60 minutes.
• Pause function
The fan can be paused for one hour using the power cord.
• Multi-pole switch
The fan is fitted with a multi-pole switch, which means that an
external switch is not required.
• LED indicators
A light-emitting diode with three different colours indicates
which mode the fan is in at any one time.
• 12-Volt motor
The motor is a long-life motor, with a life span of approx.
60,000 hours. This type of motor also runs silently.

INSTALLATION GUIDE
1. Contents
The packaging should contain the following:
• Fan
• 2 adapters, 1 x Ø98 mm and 1 x Ø118 mm
• Manual
• Accessory bag with 4 screws and plugs, a pull cord with
toggle, and insulation for the standard cable type (FK)
2. Installation
The fan can be installed on a wall or on
a ceiling. See the diagram below for
installation dimensions. The fan must not
be installed in an environment where the
temperature exceeds 50°C. Attach an
appropriate adapter to the fan's chassis,
Ø98 (1) for a Ø100 duct or Ø118 (2) for
a Ø125 duct.
The fan can also be installed and used without an adapter, so that
it is mounted completely on the surface, e.g. in the case of ducts
less than Ø98.When installing the fan, check that there is a seal
between the pipe/duct and wall/ceiling to prevent humid air from
penetrating the wall or ceiling. Use the accompanying screw and
plug, if necessary.

3. Wiring
• Installation work should be performed by a qualified
electrician.
• The fan is double insulated and must not be earthed.
• The fan is fitted with a multi-pole switch and does not require
a pre-wired external switch.
1 Push the multi-pole switch up to position 0 – OFF.
2 The cable can be installed either along the surface using
entries A in the chassis or concealed using the B inlets in the
chassis. Both options are shown below. Use the insulating
sleeve supplied for the cable (FK).
3 If you use any of the B inlets, remove the concealed round plas-
tic cover by tapping inside the break-off notch from the inside
out to the back with a screwdriver, for example.

4. Installation options
The fan can be installed in any of three ways depending on
the desired function, as detailed below:
1 Humidity control only, see diagram 1
The fan is connected to constant phase (L) and
neutral (N) for automatic humidity control.
The timer can be activated manually by installing a pull cord
and pulling it (see page 8).
2 Humidity control + timer with light switch,
see diagram 2
The fan is connected to constant phase (L) and
neutral (N) for automatic humidity control.
Switched live (SL) is connected to activate the fan's timer, i.e.
when the bathroom light is switched on,
current is present at switched live. This option
provides a 90-second start delay.
3 Humidity control + timer with retractive switch,
see diagram 3
The fan is connected to constant phase (L) and
neutral (N) for automatic humidity control.
Switched live (SL) is connected to activate the fan's
timer using a retractive switch.
This option gives direct start-up of the fan.

5. Connecting the pull cord switch
A pull cord can be installed for activating the timer manually or for
pausing the fan. Remove the mounting plate using a screwdriver, for
example, and thread the accompanying pull cord through the hole.
• Once installation is complete, push the safety switch down
to position I – ON, to make the fan active again.
When the fan is connected to the power supply, it performs a
self-test where electronics, LEDs and operation of the motor are
all tested. The fan is now ready for use.
NB!
Use an ordinary round file to
create a smooth cut-out at a
suitable place in the front cover.
Do NOT use pliers or similar
tools, as these may cause the
cover to crack.

ADVANCED FUNCTIONS
1. Selecting humidity sensitivity mode
Bathroom climates may vary depending on a number of factors:
room size, the presence of any natural draught ventilation,
temperature, etc. These factors may have a bearing on fan humidity
response, causing it to start too quickly or too slowly.
The factory setting is position 2: normal humidity response, which
works best in most cases. There is also the option of completely
switching off the humidity function.
1) Press the Speed + and
Humidity mode buttons
simultaneously (the blue and yellow
LEDs flash quickly).
Press the Humidity Mode button until
the desired humidity
sensitivity mode is selected.
Position 1: the Silent LED
comes on – fast humidity response.
Position 2: the Max LED
comes on – normal humidity
response.
Position 3: The Silent and Max LEDs
come on together
– slow humidity response.
Position 4: Both the Silent
and Max LEDs stay off
– humidity control is
deactivated.
2) Press the Speed + and
Humidity Mode buttons at
the same time (The blue and
yellow LEDs stop flashing).
