Product Item 
This guide provides installation, setup and specification information for the LEDsmart+Push Button Dimmer/Switch, item number 
MMDM/PB. 
Product summary and capabilities 
Designed in Australia to provide optimised dimming of LED based lamps and drivers, this high quality, two-wire phase control 
dimmer can be connected in parallel to other LEDsmart+devices to provide a simple solution to multi-way control. 
Although optimised for LED lighting loads, the dimmer also provides excellent compatibility with other common lamp types such 
as incandescent lamps, 12V halogen (dichroic) lamps and dimmable CFL’s. 
Programmable setup functions 
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 
The maximum brightness level provided by the dimmer can be set to suit customer requirements 
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 
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 
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 
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™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.
