Programmable setup functions
Setup functions
Description
Minimum Brightness
If an LED or CFL lamp becomes unstable at low dimming levels, it can flicker or pulse on/off. The
dimmer’s minimum brightness can be set to a level above the point at which a lamp flickers/pulses
Maximum Brightness
The maximum brightness level provided by the dimmer can be set to suit customer requirements
Kick Start
This function is only required when dimming some LED and CFL lamp’s. To ensure these lamps
switch on, they require the dimmer output to be set to 50% for 0.2 of a second when the lamp is
turned on.
Default: The Kick Start feature is switched off
LED indicators
The dimmer’s white LED indicators can be set to glow on or turn off when the dimmer is switched
off
Default: The white LED indicators are set to glow on when the dimmer is turned off
Separate Switch Mode*
Some lamps, such as non-dimmable CFL’s, can flicker when switched OFF using the dimmer’s
integrated switch. In these cases, the dimmer can be used in ‘Separate Switch Mode’ and
combined with a separate mechanical switch
Default: Separate Switch Mode is switched off
Toggle / Memory
Dimmer
The dimmer has the option to turn on at the brightness level set when the lights were turned off
(memory dimmer), or to turn on at the maximum brightness level (toggle dimmer).
Default: the dimmer is setup as a toggle dimmer
MultiMate™ON/OFF
MultiMate™functions can be switched ON or OFF
Default: MultiMate™features are switched on
*Note: Separate Switch Mode is suitable for single LEDsmart+installations only. For multi-way installations, see the note below.
There are a wide range of LED and CFL lamps available from different manufacturers. The following issues are
occasionally seen when used in conjunction with 2-wire dimmer/timer/switch products.
When switched off, the LED/CFL lights flicker, pulse on/off or do not switch off completely
When switched off, the LEDsmart+LED indicators flicker
When switching on, the LED/CFL lights have difficulty switch on and the dimmer indicators flicker or pulse
It is recommended to install a Diginet ‘Load by-pass’ device (Diginet item number MMBP) across Load and
Neutral terminals to provide improved performance of these lamps.

Multimate™technology
MultiMate™is a technology inside Diginet’s range of high quality LEDsmart+dimmers, timers and electronic light switches. It
allows multi-way control of lighting without the need for an expensive control system. MultiMate™technology is suitable for both
new and retrofit installations.
MultiMate™technology enables multiple LEDsmart+two-wire devices to be wired in parallel when two-way, three-way or multi-
way dimming and switching is required. When connected in parallel LEDsmart+dimmers allow dimming (and switching) of
connected lighting loads from multiple locations without any additional wiring. No strapper wires, dedicated remote switch
wiring or ‘control bus’ is required.
MultiMate™is a patented technology, developed in Australia by Gerard Lighting.
The wiring example below shows three LEDsmart+dimmers connected in parallel to provide three-way dimming and switching of
four downlights without any additional wiring.
Products with MultiMate™technology included
The following products all include MultiMate™ technology and can therefore be connected in parallel to allow multi-way control.
Note that different types of MultiMate™ products can be connected in parallel. For example, switches and dimmers can be
connected in parallel to control the same group of lights from different locations and/or provide additional functionality.

B: Setting Minimum Brightness
The minimum brightness level provided by the dimmer can be set to suit specific lamps and/or customer requirements.
For the majority of lamps a minimum level as low as 0% can be set if required. However, some lamps can become unstable at
low dimming levels, in particular CFL’s.
If lamps become unstable at low dimming levels, they typically flicker or pulse on/off. The dimmer allows the minimum
brightness to be set to a level above the point at which the lamp flickers/pulses.
Step 1
Enter into the dimmer Setup Mode - See PART A (page 9)
Step 2
Click the dimmer push button twice
Step 3
LED will blink 2 times
Note: To cancel/exit do nothing for 30 seconds
Note: If more than one dimmer is connected to the same load (see pages 5-7), all
dimmers connected to this load will now blink 2 times
Step 4
Adjust dial to required MINIMUM brightness level
Note: If more than one dimmer is connected in parallel (see pages 5-7), wait for 3
seconds for the other connected dimmer to learn the new minimum level
Note: To cancel/exit do nothing for 30 seconds
Step 5
Click once to save & exit
Note: If more than one LEDsmart+device is connected in parallel, the minimum
brightness levels only needs to be set in one device. The setting is automatically

INTRODUCTION
LEDsmart+ dimmers, timers, switches and occupancy sensors include MultiMate™technology. These
devices have revolutionised multiple point control of lighting whilst using conventional wiring practices.
Even when not used for multi-way control, their superior compatibility with LED lighting loads makes them
the best wall plate lighting controls in the market.
MULTIMATE™ TECHNOLOGY
MultiMate™ is the technology inside the
range of high quality LEDsmart+ dimmers,
timers, switches and occupancy sensors. It
allows multi-way control of lighting loads
without the need for an expensive control
system. MultiMate™ technology is suitable
for both new and retrofit installations.
MultiMate™ technology enables multiple
LEDsmart+ two-wire devices to be wired in
parallel when two-way, three-way or
multi-way dimming and switching is
required.
When connected in parallel, LEDsmart+
dimmers, timers, switches and occupancy
sensors allow dimming and switching of
connected lighting loads from multiple locations without any additional wiring. No strapper wires,
dedicated remote switch wiring or control bus is required.
HOW MULTIMATE™WORKS
MultiMate™products use a patented method of communicating with each other using the mains wiring. By
this means dimmers, timers, switches and occupancy sensors can communicate on/off, level, and settings
to other LEDsmart+ products on the same circuit.
INSTALLATION
In normal cases, existing switches can be removed and replaced by MultiMate™dimmers, timers, switches
and occupancy sensors. Please refer to the installation instructions for common wiring methods used for 1-
way, 2-way, 3-way and other configurations.
TROUBLESHOOTING
Like all products, sometimes there can be problems caused by the electrical behaviour of the building
wiring, or that of the lighting loads. This document describes some cases found from real-world product
experience and their solutions.
Each of the following pages describes a problem and solution. In some case additional product(s) may be
required.

FLICKERING OR FLASHING WHEN OFF OR AT LOW DIMMING LEVELS
Modern LED lighting has revolutionised high brightness low power
lighting.
Unfortunately, some LED loads can have problems with dimmer
compatibility. This can be observed when lamps flicker or flash
when set to low dimming levels or when a MultiMate™device is
set to the OFF condition.
The MMBP load bypass is wired across the lamp. It will resolve
almost all issues associated with dimming of LED lighting,
including:
-Lamp glow when turned off;
-Flickering or pulsing of the lamp when turned off or to low
dimming levels; and
-Flickering or pulsing of the dimmer LED status indicators.
Solutions for lamp flickering at low dimming levels
Solution 1: Use the setup functions of the dimmer, timer, switch or occupancy sensor to adjust the
MINIMUM dimming level to a higher value. Refer to the product installation guide for details.
Solution 2: Fit a load bypass device –order code MMBP.
Solution 3: In extreme cases, both the MMBP and a raised minimum level may be needed.
Solutions for flickering or pulsing of dimmer LED status indicators.
Solution 1: Fit a load bypass device (MMBP).
Solution 2: Newer model dimmers introduce CLM mode. Use the setup guide for your product and activate
CLM mode.
Solution 3: In extreme cases, both the MMBP and enabling CLM mode may be needed.
Solutions for lamp flickering or flashing when turned OFF
Fit an MMBP load bypass. It is designed for this issue. Similar products are also available from other
manufacturers.
How to install the MMBP load bypass device
The MMBP load bypass device is installed in parallel with the load, across the switched Active and Neutral,
as shown in the diagram below.

CROSSTALK
Crosstalk happens when several MultiMate™ circuits are installed in
the same building, and adjustments on one circuit cause interference
on another circuit. The interference may be observed as:
-Lighting changes on one circuit cause lighting changes (on / off
/ change of level) on some other circuit; or
-Lighting changes on one circuit cause another circuit to turn
off.
If a lighting load is flickering or flashing at low dimming levels or when
turned off (and no dimmer / timer / switch is being adjusted) the most
likely cause is a poorly designed lighting load. In that case, please refer to the section “Flickering or flashing
when off or at low dimming levels”.
Causes
If the mains supply has a high source impedance, this can cause crosstalk: where the communication of one
set of dimmers interferes with adjacent dimmers –especially if the different dimmer circuits share a
common active feed to the same switch plate.
Reasons for High source impedance may include one or a combination of:
•Old substation or local step-down transformer running close to maximum capacity;
•Long cable run from step down transformer to building;
•High resistance terminations on active feeds and/or neutral returns; and
•Neutral returns from a common active feed having significantly different run lengths back to the
switchboard –good practice would be to link together neutral returns from a common active feed as
close as possible to the loads.
A best practice is for wiring from the distribution panel to the multi-way control location to use twin &
earth cabling, keeping active & neutral together for as long as possible. This results in the lowest supply
impedance. Long runs of single-cable active wiring and separate neutral wiring should be avoided.
Solution when the Multi-way function is not required
If the multi-way dimming function is not being used: follow the directions in the product Setup Guide to
disable the MultiMate™ operation. This prevents the dimmer / timer / switch / sensor from sending and
receiving the MultiMate™commands.
Change this setting for all affected dimmers in the building when multi-way dimming is not needed.
Solution when the Multi-way function is required
When the multi-way dimming function is required, an inline MMDM/ID Inductive Decoupler may be
required –these should be connected between the last dimmer in the control chain and the load.

FANS, FLUORESCENT LIGHTING AND NON-DIMMABLE LOADS
MultiMate™dimmers, timers, switches and occupancy sensors are designed to control dimmable lighting
loads.
Sometimes these products need to control non-dimmable loads, for example fluorescent lighting, non-
dimmable LED lamps, or bathroom exhaust fans.
Direct wiring of these loads to MultiMate™products may cause incorrect function of the load or the
MultiMate™product.
To Control fans and non-dimmable loads
The MMSR MultiMate™Slave Relay presents a dimmable load to
MultiMate™devices. When the dimmer level exceeds a threshold,
the relay is operated and switches on a non-dimmable load.
Combinations loads are possible on a dimmer: a dimmable LED
load may be used on the same circuit as non-dimmable loads. In
this case, when the dimmer level is higher than a threshold, the
relay is operated to switch the non-dimmable load(s) on and the
dimmable load will continue to respond normally. This is shown in
the wiring diagram below.
Properties of the MMSR Slave Relay
The Slave Relay has voltage-free contacts, and is rated at 10AX.
SELV load control is possible when using the isolating barrier that
is included.
The Slave Relay is suitable for use with trailing edge phase control dimmers. The Slave Relay can satisfy the
load requirements of LEDsmart+ dimmers / timers / switches or occupancy sensors by itself. Using an
additional dimmable lighting load is optional.
