[3] Connect the two disconnected wires to the two
leftmost terminals: [1] the (brown) “hot wire”, [2]
the (black) “switch wire”. Tighten the clamping
screws.
[4] Connect a (blue) neutral wire from the wall to
one of the two rightmost terminals [3] or [4]. It does
not matter which one you choose. Continue with
step [7].
In practice, there is often no neutral wire
present for a 2-way switch. If not, one must be
installed!
The existing switch must be a 2-way switch
(not a 3-way switch for control from two locations)!
Your wire colours may be different! If in doubt,
ask your installer!

A maximum of 6 different transmitter codes can
be stored simultaneously.

Remarks
Reminders
• This product is intended for installation in a wall or ceiling junction box and must be used in combination
with at least one COCO transmitter.
• This product is a dimmer/receiver: control lights (or other suitable devices) remotely, without
complicated wiring.
• To prevent interference, avoid placing multiple products close to each other. The minimum distance
between units should be approx. 50 cm.
• The wireless system can be expanded indefinitely with other COCO remote controls and/or receivers.
• Your COCO transmitter may have a special "group" button with which multiple receivers with different
settings can nonetheless be controlled simultaneously. Repeat [8 - 10] and press the "group" button on
the transmitter during step [9].
• During a power failure the codes remain in the memory.
• To delete the stored codes (resetting the memory): (1) Hold in the search mode button. (2) The
indicator begins flashing after approx. 7 seconds. (3) Release the search mode button. (4) Briefly press
the search mode button again. (5) To confirm, the connected device switches on and off two times.
• If the product does not work:
- Reset the memory (see previous line) and set the code from the transmitter again (repeat [8 - 10]).
- Check whether the indicator is lit; if not, there may be no power to the product or the fuse may have
blown.
- Fuse replacement: (1) Open the wall or ceiling junction box. (2) Pry open the fuse holder with a
screwdriver. (3) Press the fuse out of the holder (the fuse will be slightly blackened if it is blown). (4)
Press the new fuse into the holder. (5) Press the holder into the dimmer and close the wall or ceiling
junction box.
