Airflow iCON SELV 12V fans can be controlled by optional
control modules. For the SELV 12V range you can choose
between six modules.
* For blister pack add “B” at the end of part number.
SAFETY FIRST: ALWAYS ISOLATE THE FAN
UNIT FROM THE POWER SUPPLY BEFORE
DOING ANY WORK ON THE FAN/MODULE.
All electrical installation work to be carried out by an ap-
proved competent person in compliance with U.K. Building
Regulations and to the latest IET standards, or the appropri-
ate regulations in the country of installation. (for fan installa-
tion see the iCON SELV 12V Fan Range Installation and
Operating Guide).

To install the module in an iCON fan follow the instructions
below. See page 5 - 8 for instructional drawings.
1. Remove the iCON fan front cover (see page 5).
2. Lift the fan electrical terminal away from its mounting pillars
and position on the module connector pins. Tighten the two
screws with a suitable screwdriver. Ensure the leads are
under the module retaining cable clamp.
3. Fit the module at a slight angle into the fan housing, ensur-
ing that the locating slot is fully engaged in to the locating
block on the fan.
4. Push the module against housing, ensuring the module clip
holds it in place (clicks at the cable clamp). With iCON 15
& 30 the terminal will reposition back over mounting pillars.
Modules with pull cord: Ensure that the pull cord is properly
located within the cord slot at the bottom of the fan.
Modules with PIR control: Remove the oval logo cap fitted
at the bottom of the front cover of the fan. Replace it with
translucent lens supplied with the PIR module. Note: The
lens must be replaced in order for the PIR module to function
properly. Ensure the orientation of the lens is correct (i.e. the
lens should be flush with the surface).
Connecting mains cable into the module
Connect the 12V Power Supply Unit cable to the 3-way sup-
ply connector block (see wiring diagrams on page 3) ensur-
ing that the supplied cable clamp is fitted. Refit the front
cover.
Note: When using DTS module on initial connection the fan
will start immediately and continue running for the duration
set on the timer function of the module.

location
To remove front cover assembly, first make sure the fan is
off, isolated from the power supply and the iris shutter is
fully closed.
1. Undo the locking screw at the bottom edge of the cover
using a screwdriver.
2. Rotate the cover a few degrees anticlockwise until it clicks
out from the fittings.
3. Remove the cover by pulling it out.
To refit the cover, reverse the above procedure. The iris
shutter should be in closed position after refit. If not, wait
approximately 1 min after fan switch off allowing the actuator
to retract back in the closed position and then refit the cover
again.

iCON module overview.
A module with Timer and/or Humidistat is supplied pre-set,
but may be adjusted by the installer. All adjustments must be
done using the supplied Adjustment Tool.
Humidity settings
The humidistat is factory pre-set at approx. 70% RH (relative
humidity). Adjusting the “% RH” towards 40% will result in fan
activation at lower humidity (more sensitive). Adjusting the
“% RH” towards “90%” will result in fan activation at higher
humidity (less sensitive).
Time settings
The Run on Timer is factory pre-set at approx. 15 min. Ad-
justing the “Timer” towards “MIN” will result in a timer overrun
decrease towards 1 or 2 minutes (depends on module).
Adjusting the “Timer” towards “MAX” will result in a timer
overrun increase towards 30 or 45 minutes (depends on
module).
