• Bottom Color Off—The LED color for the bottom LED when the LED state is OFF.

Options

• Top LED Link—If checked, swap on and off the state and color on the top LED.

• Bottom LED Link—If checked, swap the on and off state and color on the bottom LED.

• Buttons Attached—If checked, pressing the buttons on the Dimmer or Switch directly

controls the connected load.

• LED Attached—If checked, the LED state is controlled by the button presses. If

unchecked, the LED state and colors can be controlled by custom programming.

Hold Ramp Rate

• Up—The rate in seconds when the load increases when the Top button is held down.

• Down—The rate in seconds when the load decreases if the Bottom button is held down.

Network—The current MAC address and firmware version of the selected Dimmer or Switch.

These fields are not editable.

The following properties apply to the Wireless Dimmer only.

Load Profile—The minimum and maximum load settings for light output which includes the Cold Start

Level and time. Test the settings to determine what fits best with your bulb type. Click Set to save

your changes.

Note: The Navigators show 0% to 100% even though the settings may be set at Minimum On

Level percent at 25%, and the Max On Level percent at 80%.

Minimum On Level (%)—Use the drop-down box to select the minimum % in 1% increments.

The default is 0. The minimum level can vary, depending on the light type (incandescent,

flourescent, LED, etc.).

This is especially important in compact fluorescent (CLF) and LED lighting that sometimes have a

minimum threshold for producing visible light that could be anywhere from the 10 – 40% range.

Some loads will flicker or pulse right at their minimum threshold.

Example: A bulb doesn’t produce visible light until it reaches 20%. The minimum On to 25% will

ensure a clean On transition.

Cold Start Level (%)—Use the drop-down box to select the start level in 1% increments. The default

is 0. This level is set above the Minimum on level % setting.

This setting is mainly applicable to CFL loads. Switching from an Off state to On sometimes

exhibits a higher visible light threshold than after the CFLs have been on and have warmed up. If

a Cold Start % is set (above the Minimum On %), the Dimmer cleanly jumps to that level from Off

to On. However, when the Dimmer has been on for the time period designated by the Cold Start

timer, the Dimmer can ramp below the Cold Start On % to the minimum On%.

Example: Fluorescent lights go on, warm up, and then will dim down to the Minimum On Level %

setting. Tapping the keypad on a 2-button Dimmer sets the light to its preset level. If you press

and hold the button, the light checks the Minimum On Level % setting.
