19About X-10The OmniLT controls lights and appliances by sending commands over your existing electrical wiring to special switches, outlets,receptacles, and modules, collectively referred to as X-10. Each module (or group of modules) is assigned a House Code and aUnit Number so that the OmniLT can control the modules individually. When a module hears a command from the OmniLT forits house code and unit number, it executes the command.There are 3 different X-10 formats: Standard X-10 (Preset Dim), Extended X-10 (Extended Level), and Compose.Any module that is "X-10 Compatible" will work with the OmniLT. The modules come in various types.House CodeOmniLT can control up to 16 lighting and appliance devices. Each device (switches, modules, and keypad) has its own UnitNumber (1-16). The “House Code” is used to configure the lighting protocol format such as: Standard X-10, Extended X-10,Lightolier Compose, UPB (open UPB format where you can use the programming capability in the OmniLT controller tocommunicate with the UPB network), Lutron RadioRA, CentraLite, or HAI Lighting Control (HLC). Only one House Code canbe configured on OmniLT.Unit NumbersOmniLT systems have 36 total Unit Numbers. They consist of HLC, UPB, Z-Wave, CentraLite, RadioRA, ALC, Compose, andX-10 module unit numbers, hardwire voltage output unit numbers, and internal flag unit numbers as follows:OmniLT Unit Numbers Module / Output Unit Numbers1 - 16 HLC or Z-Wave Room 1 and 2, UPB Unit ID 1-16, Z-Wave Node ID 1-16, CentraLite loads 1-16,RadioRA Lighting Zones and Master Controls 1-16, or X-10 modules 1 – 16 (House Code X)17 - 24 Voltage Outputs (1-16), Fully Configurable on Model 22A00-1 OmniLT Expansion Module*25 Thermostat Output (Fully Configurable)26 Bell Output27 - 28 Hardwire Outputs 1 and 2 (Fully Configurable)29 – 36 Internal Flags“X” Represents the House Code setting on the OmniLT Controller“*” If usedScrolling Through NamesThe OmniLT stores names for Units, Zones, Buttons, Codes, Temperatures, and Messages so that you don't have to rememberthat "UNIT 5" is the "DEN LIGHT" and "ZONE 1" is the "FRONT DOOR". In general, any time you enter a unit, zone, button,code, temperature, or message number, you can press the down arrow key to display its name, then use the up and down arrowkeys to scroll through the list of other names. This is true when entering commands and programming on the console. Onlynamed items are displayed on an OmniTouch touchscreen.
