1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project success-
ful. Read them carefully.
1.1 Make sure you have the right tools:
•A good quality soldering iron (25-
40W) with a small tip.
•Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the
tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and en-
ables you to make good connections. When solder rolls off the tip,
it needs cleaning.
•Thin raisin-core solder. Do not use
any flux or grease.
•A diagonal cutter to trim excess wires. To avoid injury
when cutting excess leads, hold the lead so they
cannot fly towards the eyes.
•Needle nose pliers, for bending leads, or to hold components in
place.
•Small blade and Phillips screwdrivers. A basic range is fine.
For some projects, a basic multi-meter is required, or
might be handy
1.2 Assembly Hints :
⇒Make sure the skill level matches your experience, to avoid disappointments.
⇒Follow the instructions carefully. Read and understand the entire step before you
perform each operation.
⇒Perform the assembly in the correct order as stated in this manual
⇒Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
⇒Values on the circuit diagram are subject to changes.
⇒Values in this assembly guide are correct*
⇒Use the check-boxes to mark your progress.
⇒Please read the included information on safety and customer service
* Typographical inaccuracies excluded. Always look for possible last minute manual
updates, indicated as ‘NOTE’ on a separate leaflet.

1.3 Soldering Hints :
Mount the component against the PCB surface and carefully solder the
leads
Make sure the solder joints are cone-shaped and shiny
Trim excess leads as close as possible to the solder joint
REMOVE THEM FROM THE TAPE
ONE AT A TIME !
AXIAL COMPONENTS ARE TAPED IN THE CORRECT
MOUNTING SEQUENCE !

15. Connection & operation
Note : this kit operates on mains voltage and this may
present some hazards. Disconnect the kit from the mains
when working on the PCB.
A -Power supply :
Connect the device to the mains (110 -240 Vac) through connec-
tions L & N of connector SK1.
FThis kit is available in various countries. Take care to use an
appropriate connection.
FThe connection cables should be equipped with an appropri-
ate strain relief when mounted in a housing.
B -Connect the fan :
This kit enables you to switch on a fan together with the light.
GATTENTION : check the wiring carefully when connecting to an
existing installation (see connection diagram p. 10).
—Connect the fan to output connector SK2.
—Connect Lx of connector SK1 to the cable linking the switch to
the light source in question (Ø1.5mm²).
—Connect the live (L) of connector SK1 with the live of the
mains.
—Connect the neutral (N) of connector SK1 to the neutral of the
mains.
Operation : The fan starts when the lights in the room are
switched on. After the lights have been extinguished, the fan will
continue its operation for 5 more minutes. This delay can be ad-
justed by turning potentiometer RV1.
When the lights are turned on again during the deactivation delay,
the fan timer will simply restart. The deactivation delay will restart
after the lights are extinguished.
