18The first unit number in each room (i.e. 1 and 9) is reserved for controlling the room. The name for this unit should reflect theroom name (e.g. Kitchen, Great Room, Theater, etc.). Vizia RF or Z-Wave lighting devices cannot be associated with these unitnumbers.If one or more pushbutton controllers are used, the first pushbutton controller should be set to the first unit number in the group(i.e. Unit 1); additional pushbutton controllers can be used by setting each to any other unused unit number in the group(i.e. Units 2-8).Using a console, touchscreen, or other interface to OmniLT, the room can be turned off (all loads in the group are turned off),turned on (all loads in the group are turned on), or set to one of 4 lighting scenes (A-D).About CentraLiteCentraLite is a centralized lighting control system that uses hardwired lighting control or wireless radio frequency technology tocontrol lighting loads, fans, and mechanical low voltage relays.CentraLite lighting scenes are used to control groups of lights which are preset to turn on to various levels of dimming.When set to CentraLite, the OmniLT controller can:¾ Send commands (on, off, and level) to individual loads and relays¾ Receive status (on and off) from individual loads and relays¾ Execute scene commands (on and off) to control lighting scenes¾ Receive commands when buttons are pressed on a CentraLite keypadAbout Lutron RadioRALutron RadioRA uses wireless communication technology to control lighting. Each Switch or Dimmer controls one Zone, or area,of lighting in a RadioRA system. Accessory Switches and Dimmers are used to control the lights locally from up to 9 additionallocations. Master controls provide control and monitoring for all the lights in a RadioRA system.Phantom Buttons are “virtual” buttons in the RS232 Interface. Though there are no physical buttons that represent these PhantomButtons, they work very similarly to buttons on RadioRA Master Controls. Phantom Buttons are intended to give the RS232Interface control over multiple RadioRA Switches and Dimmers with one command. To control more than one device at one time,Phantom Buttons are recommended.A Zone is any individual RadioRA Switch or Dimmer.When set to RadioRA, the OmniLT controller can:¾ Send commands (on, off, and level) to individual Switches and Dimmers¾ Receive status (on and off) from individual Switches and Dimmers¾ Receive commands when buttons are pressed on Master Controls¾ Execute Phantom Button commandsAbout ALCALC is intended for installation in homes, which have been pre-wired for installation of ALC system products. OmniLT controlslights and appliances by sending commands over the ALC signal wiring to ALC Switch Modules. ALC Switches communicatewith the OmniLT over low voltage signal wire. They are two-way devices, so the controller always knows the actual status of theswitch. In addition, ALC switches can be used to set scenes by triggering macros in OmniLT.When ALC Lighting Control Modules are being used, it is also possible to "ramp" the lighting level of an ALC Dimmer Switch toa new level at a controllable ramp rate.ALC Module TypesThe ALC modules types are: Dimmer Switch, Relay Switch, Slave Switch, Program Switch, and 4-Button Scene Switch Modules.
