TROUBLESHOOTING GUIDE
LEDSMART+ FEATURING MULTIMATE™ TECHNOLOGY

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 subject describes a problem and solution. In some case additional product(s) may be required.

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.

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”.

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.
