Features & Specifications
This dimmer is a plug-in module for our K8006 home lighting system. Just like its predecessor K8007, it was
designed for the dimming of conventional incandescent lamps and halogen lighting. Not only is this kit easy
to operate with just one push button, it is also equipped with numerous safety features. With low-voltage
halogen lighting the transformation from mains voltage to 12V lamp voltage is to be achieved by means of a
wire-wound transformer. You can use both a toroidal and an encapsulated transformer. Most electronic transformers are incompatible with this dimmer.
Specifications:
Dimmer for our K8006 home lighting system.
Suitable for incandescent lamps, mains voltage halogen lighting and low voltage halogen lighting in combination with a
conventional (wire wound) transformer.
Easy push-button operation
A brief push toggles on/off, while continued pushing engages the dimming function
Non volatile memory for last light intensity setting.
Lots of safety features to protect lamp life e.g. “soft-start” function and automatic deactivation after 12 hours or after 20 min
of operation at insufficient light intensity...
Transformer prote ctio n in case of defe ct ive lig ht so urce s.
LED status indication.

1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project successful. 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 o r c loth , to ke ep it c lean ; th en apply so lder to th e t ip, to g ive it a wet look. This is called ‘thinn ing’ an d w ill
protect the tip, an d enab les you t o make good conn ections. When so lder ro lls of f th e tip, it ne eds clean ing.
• Thin raisin-core solder. Do not use any flux or grease.
• A diagonal cutter to trim excess wires. To avoid in jury wh en cutting ex cess leads, ho ld the lead so th ey
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 poss ible last m inu te manu al updates, indicated as ‘NOTE ’ on a separate leaflet.

1.3 Soldering Hints :
1- Mount the component against the PCB surface and carefully solder the leads
2- Make sure the solder joints are cone-shaped and shiny
3- Trim excess leads as close as possible to the solder joint
REMOVE THEM FROM THE TAPE ONE AT A TIME !
