The latest version of the TR002Y-1 has only one button for the lights rather then two. On the older model each of the lighting groups (ceiling light and panel lighs) could be activated seperatly.

Only one set of light can be activated from the electronic control pad, to activate the other set you must use the Remote control to do so.

Alternatively you may choose to wire ALL of the lights together and use the button on the Electronic control pad to activate all lights at once.
