Green Button

Enact four energy-saving solutions with a single touch using the "Green" button:

1. "Green" trim: Dimmers reduce their output by 5% throughout their range—without affecting scene LEDs or the level indicated on the dimmer. "Green" trim can be adjusted up or down based on your preferences.


2. Shades: Lower your shades to reflect the sun's heat in the summer, or to create an insulating layer to keep heat in during the winter.


3. Appliances: Turn off unneeded appliances to save energy.


4. Temperature (coming soon): Set back your thermostat to reduce heating/cooling costs.

Multiple green buttons may be programmed to customize your energy-saving strategy for different times of the year, or the day.
