ing zone assigned to that button is ON at any level. When issuing an "ON" command, a
ROOM button may only turn zones ON, not OFF.
SCENE Button - A SCENE button is a programmable button whose LED is ON when the
SCENE associated with that button has been activated. The LED will go out when the light

as its preset level. The LED will also go out if the SCENE is turned OFF. When issuing an
"ON" command, a SCENE button may turn zones ON or OFF.
