Performance
Power failure memory: Should power be interrupted,
the control will return to its previous state when
power is restored.
Tested to withstand surge voltages without damage
or loss of operation, in accordance with
IEEE C62.41-1991 Recommended Practice on Surge
Voltages in Low-Voltage AC Power Circuits.
Tested to withstand electrostatic discharge without
damage or memory loss.
For 3-way and 4-way dimming, use Maestro
companion dimmers. One dimmer can be used with
up to 9 multi-location companion dimmers.

3
SSL-7A-2015 compliant when in forward-phase.
4
When using magnetic (core and coil) low-voltage transformers with halogen lamps set the dimmer to forward-phase. When using with dimmable electronic (solid-state) low-voltage
transformers set the dimmer to reverse-phase.
5
Operation of a low-voltage circuit with lamps inoperative or removed may result in transformer overheating and premature failure. Lutron strongly recommends the following:
Do not operate low-voltage circuits without operative lamps in place.
Replace burned-out lamps as soon as possible.
Use transformers that incorporate thermal protection or fused transformer primary windings to prevent transformer failure due to overcurrent.
6
When using the dimmer / switch to control MLV halogen fixtures, the maximum lamp wattage is determined by the efficiency of the transformer, with 70%–85% as typical. For actual
transformer efficiency, contact either the fixture or transformer manufacturer. The total VA rating of the transformer(s) shall not exceed the VA rating of the dimmer / switch.

Includes Philips Advance Mark 10® ballasts, Sylvania®, Tu-Wire, and POWERSENSE®.

Advanced Programming Mode
Maestro dimmers and switches contain an Advanced Programming Mode (APM) that allows users to customize
the control to meet their specific needs. For a detailed description of APM features and uses please refer to Lutron
Application Note #703 (P/N 048703) at www.lutron.com
Instructions for selecting phase:
1. Open the FASS.
2. Press and hold . Close the FASS and continue to
hold for 5 seconds.
Note: The current phase selection will illuminate:
IL7 (top, forward-phase)
IL4 (middle, phase auto-select-default with no
neutral)*
IL1 (bottom, reverse-phase-default with neutral)
3. Press the or to get the desired selection.
4. Press
T
to exit Phase Selection mode.
*Phase
Auto-Select
* Phase auto-select defaults to reverse-phase unless
the LED load cannot operate correctly. It will then
switch to forward-phase automatically. Phase
auto-select is only available when no neutral wire
is connected.
