The LED relay zone controller uses wireless technology to communicate with other self-powered EnOcean based products and
provides an amazingly simple solution for dimming control of
LED lighting.
The compact size enables exible installation inside of or next
to electrical boxes and xtures so it can be easily wired out of
sight using standard wiring practices.
Simply link the module to an EnOcean-based motion sensor,
light level sensor or rocker switch and experience levels of
efciency and convenience that can only be achieved through
wireless controls.
It is also possible to link TWR-D10 to a central controller or via a
gateway to building automation systems like BACnet.
Features Include:
▪ Enables wireless dimming of a single xture or a zone of
multiple daisy chained LED xtures (e.g. 20 each 30W or
10 each 60W).

7. Restore power to the circuit.
8. Use the setup interface to
link devices and congure
settings (refer to the “Linking”
& “Conguring” sections).
Warning: Remove the
module from the electrical
box to use the setup
interface.
3) Device Conguration
The LED controller can be congured in two ways:
▪ By user input to the local setup interface
This approach is used for basic setup tasks
▪ Remotely using the remote commissioning interface
This approach is used for advanced conguration tasks
Local Setup Interface
The local setup interface has two buttons, LRN (O) and DIM.
LRN (O) has a corresponding 2-color LED (green, red). This
simple interface is used to link and unlink transmitters, to dim up
and down manually and to set the minimum dimming value.
To use the local setup interface, hold the module so both
thumbs can click the buttons without obscuring the LED.
LRN (O) button
Press short to start or end
linking/unlinking mode.
Press long (>10s) to delete all
linked transmitters.
LRN (O) LED
The LED will toggle red/green every 2 seconds,
while in linking/unlinking mode. After linking
(unlinking) a device it will stay green (red) for 4
seconds. The connected load will toggle between
10% and 90% dimming level, respectively.
When the button is pressed
shortly (<0.5s), the connected
load is switched ON/OFF. If
pressed longer, the 0-10V output
starts dimming up and down the
connected load. If pressed
output value will be stored as
minimum dimming level. When
shortly (<0.5s) pressing the button
while in learn mode, TWR-D10
will transmit a teach-in telegram.
Remote Commissioning Interface
The LED controller provides a wireless remote commissioning
interface for all commissioning tasks.
This interface allows conguring all device parameters
wirelessly using a laptop computer equipped with Navigan
Wireless Commissioner (WIS-NWC-USB), consisting of a USB
wiSTAR™ Dimming Control Module • Installation Guide
4) Linking
Linking is the process by which different devices are congured
to work with each other in a system. Sometimes this process is
also called Teach-in or Learn-in.
The LED controller can work together with two types of devices:
▪ Transmitters (switches and sensors) can provide input data
to the LED controller.
▪ Transceivers (Gateways or controllers) can exchange data
and commands with the LED controller.
There are two basic types of devices in the system; transmitters
and transceivers:
Transmitters (Transmit-only)
Transmitters are energy-harvesting devices that send RF messages to communicate a condition, level, or state. The following
transmitter types can be linked to the LED controller:
▪ Switches▪ Occupancy Sensor▪ Light Level Sensor (only in addition to switches and
occupancy sensors, not alone)
Transmitters can only be linked to transceivers, not to other
transmitters.
Transceivers (Transmit & Receive)
The LED controller is a transceiver. Transceivers are control-
ling devices that send as well as receive RF messages. They
also process relevant control logic, and actuate the appropriate
outputs (switching a light ON or OFF for example).
The LED controller can be linked to other transceivers if desired. The following other transceiver types are supported:
▪ Demand Response Controller▪ Central Controller
Linking to transmitters (sensors or switches)
To link the LED controller with a transmitter, the LED controller
must be powered, within wireless range of the transmitter it is to
be linked to, and set to linking mode to accept links.
Once these conditions are met, the desired transmitter is triggered to send a special link message.
The LED Controller receives this link message and stores the
link parameters permanently so that the two devices can interact to provide a variety of intelligent control options.
time to link / unlink multiple devices. The mode will stop
after 30 seconds if no LRN (O) telegram is received.
2. For the transmitter to be linked, do one of the following
according to the type of device:
A. Sensor: click the designated link button.
B. Rocker Pad: click the “I” button (top button marked on
the switch plastic or “I” symbol on the back of the switch) 3
times quickly.
3. If the device has been linked successfully, the LRN (O) LED
will display solid green for 4 seconds. The LED controller is
now ready to accept new links.
NOTE: After a device is linked, additional learn telegrams
received in operating mode (not in linking / unlinking mode)
from that device will cause the connected load to toggle
once between 10% and 90%, if the EnableLinkChecker
parameter is set to ON.
This allows quickly checking the connection between this
device and the LED Controller.
4. For a linked transmitter to be unlinked, please use the same
action as described in point 2 above.
5. If the device has been unlinked successfully then the LRN
(O) LED will display solid red for 4 seconds and the load will
be switched to a dimming level of 10% for 4 seconds.
6. To exit linking / unlinking mode and return to normal opera-
tion, wait 30s without sending new LRN (O) telegrams, or
shortly press the LRN (O) button again.
Clear all linked transmitters
In order to clear all linked devices press and hold the LRN (O)
button for 10 seconds. After that the LRN (O) LED will display
solid red for 10 seconds.
Linking to Transceivers (gateways or controllers)
1. Set the other device into linking mode
2. Shortly press the LRN (O) button.
The LRN (O) LED starts toggling indicating that linking /
unlinking mode is active. The connected load will toggle
between 10% and 90%.
3. Shortly press the DIM (I) button. This will cause the LED
Controller to transmit a teach-in message identifying the
status message EEP used by it.
4. Shortly press the LRN (O) button again to return to normal
operation.
Setting the minimum output voltage level
Link / unlink procedure
1. Shortly press the LRN (O) button to enter linking / unlinking
mode.
The LRN (O) LED starts toggling red / green indicating that
linking / unlinking mode is active. In addition, the connected
load will toggle between 10% and 90%.
Once activated, this mode stays temporary active to provide
It is possible to congure the minimum output voltage
(MinVoltageLevel) of the LED Controller via its button interface.
This level is typically set to avoid ickering and will be the mini-
mum level the load starts at when it is switched on. It will not be
possible to dim the output below this value.
Use the following steps to congure this minimum dimming
value:
Page 4
wiSTAR™ Dimming Control Module • Installation Guide
1. Press and hold the DIM (I) button.
The load will start dimming up and down.
2. Release the button when the desired minimum output volt-
age (dimming value) is reached.
3. Shortly press DIM (I) and LRN (O) button simultaneously to
store this value.
Double click (<0.7s) on “I” button: Light is switched ON immediately at MaxVoltageLevel (default 10.0V).
Short click (<0.7s) or double click (<0.7s) on “O” button (Bottom
button marked on switch or “O” symbol on back of switch): The light is
switched OFF, the current dimming value is stored.
Press and hold “I” or “O” button: Light is brightened or dimmed
until button is released or MinVoltageLevel / MaxVoltageLevel is

reached.
Ramp up (RockerSwitchRampUpSpeed) and down (RockerSwitchRampDownSpeed) speeds for rocker operation are
congurable (default 20% per second).
Light can be automatically switched OFF automatically in ab-
sence of an occupancy sensor after time-out of RockerSwitchAutoOffTimer. This feature can be disabled by setting RockerSwitchAutoOffTimer = 0.
This feature is automatically disabled if an occupancy sensor is
present. In this case, automatic switch OFF of the light will be
performed based on the input from the occupancy sensor as
described below.
Occupancy Sensors Only
If at least one sensor detects motion, light is set to OccAutoOn-
Level (default 100%). If none of the sensors detects motion,
light is set to OccAutoOffLevel (default 0%), after OccAutoOffTimer (default 15min) has elapsed.
Ramp up (SensorRampUpSpeed) and ramp down (SensorRampDownSpeed) speeds are congurable (default 20% per
second).
Occupancy Sensors and Switches
Light can be switched ON / OFF manually, function as described
above. Once OccAutoOffTimer (default 15min) has elapsed the
light will be set to OccAutoOffLevel (default 0%).
Light will be automatically turned back ON at the last state, if
occupancy is detected within the OccGraceTimer period (default
45s) after an occupancy sensor Auto OFF event.
The system can also be congured (OccAutoOn) to automati-

10.0V). Dimming below MinVoltageLevel or above MaxVoltage-
Level is not possible.
Level and ramp percentage levels refer to the interval between
MinVoltageLevel (1%) and MaxVoltageLevel (100%). An output
level of 0% equals OFF state.
Light Level Sensor
WIS-IDM supports the integration of a light level sensor in an
open-loop system for daylight harvesting.
The light level sensor adjusts the light level according to incoming ambient light. The light level sensor will not switch ON the

light by itself; therefore it works only in conjunction with rockers
or occupancy sensors in the system.
The light level sensor should be placed at a position facing the
window or skylight where it is not or only minimally inuenced
by light from the xtures.
Page 5
wiSTAR™ Dimming Control Module • Installation Guide
If a light level sensor is connected, the LED controller will by
default activate daylight harvesting with continuous open loop
dimming according to a user-dened dimming curve based on 5
congurable supporting points.
Each of these 5 supporting points denes the output light level
set by the LED controller for a specic input illumination level
reported by the light sensor.
In order to start dimming based on illumination the light must be
switched ON either via rocker switch or by an occupancy sensor
Auto ON event, depending on system conguration.
After a double click (<0.7s) on the “I” button of the light level
sensor, after brightening or dimming via “I” or “O” button or after
switch ON via occupancy sensor input, light will stay at the set
level until switched OFF manually or by an occupancy Auto OFF
event or until the LlsOverrideTimer (default 15 minutes) elapses.
Users can adapt the output level of the LED controller for the
current illumination level reported by the light level sensor.
This is achieved using a fast triple click (<0.7s) on the “I” button.
Doing so will replace the supporting point matching most closely
the current reported illumination level reported by the light level
sensor with the current light level and the current 0-10V output
level.
Doing that at different daylight levels allows dening the whole
curve. In addition these supporting points can also be cong-
ured by remote commissioning.
The light level sensor can alternatively be used to activate an
automatic switching mode between MaxVoltageLevel and MinVoltageLevel based on light intensity.
This can be achieved by conguring DaylightingMode to 2-level
via remote commissioning.
The thresholds for switching between these levels are dened
by PhotoOnThres (output will be set to MaxVoltageLevel for
reported values below this level) and PhotoOffThres (output will
be set to MinVoltageLevel for reported values above this level).
Repeater Function
The LED controller provides the option to activate a one or
two-level repeater for EnOcean radio telegrams. This function is
only available via remote commissioning.
1-level repeater: If a received telegram is a valid and original
(not yet repeated), the telegram is repeated after a random
delay.
2-level repeater: If a received telegram is valid and original or
repeated once, the telegram is repeated after a random delay.
Note: 2-level repeating function should only be activated if
really needed! Otherwise the system function can be compromised by collisions of telegrams.
be switched off completely. By setting it to 0xFFFF only event
based messages will be sent.
Central Controller
WIS-IDM can also be connected to a central controller (EEP A538-00). It supports the dimming command 0x02 of this EEP.
