Newer Wall Switches and Preset Dim

Question

I bought an X10 dimming wall switch in 2007 or later and its manual does not seem to describe its behavior correctly. Do you have updated instructions?

Answer

Most X10 dimming wall switches manufactured in 2007 or later have SoftStart and Preset Dim features added. By default, tapping the switch will bring the switch on at full brightness. You can set the switch to come on at a dim level instead.

Setting Preset Dim

Tap the switch so it comes on at full brightness. Press and hold the switch; the light will dim. Release the switch at the desired level. Tapping the switch will now alternate between off and dimmed.

Clearing Preset Dim

If the light is off, tap the switch once so it is on but dimmed. Press and hold the switch for 5 seconds; the light will dim further until it is almost off. Release the switch, then press and hold it for five more seconds; the light should come on at full brightness.

Controlling From Active Home Pro
