SYSTEM OVERVIEW • INTRODUCTION
Chapter 1: System Overview
Leviton’s Centura System is the convenient, Fluorescent Dimming and Energy Management System.
The system is designed with both the average user and the building administrator in mind.
By combining a number of state-of-the-art lighting control and sensor products, Centura provides
numerous functional advantages.
• Daylight Harvesting Exploits Outside and Ambient Light
• Lights Turn On and Off Automatically Based on Occupancy and Lighting Needs
• Computer Control Over Light Fixtures
• Lighting Adjustments Using Hand-held Remote
• Centralized Control Over Lighting System Settings
• Interface with Auxiliary Systems for Additional Savings and Safety
(HVAC, Emergency, Time Clock, and Loadshed)
As you will see, Centura provides a number of options for interfacing with the system.While both
the average user and the lighting administrator can, of course, use any of the wall-mounted controllers
or the remote control to adjust lighting, Leviton also provides “Personal Dimmer” software tailored to
the needs of each group.The average user, who wants to know how to use the system to make
temporary and long-term adjustments to your lighting, should reference Chapter 2 next. If you are
a building administrator responsible for lighting, you will also be interested in Chapter 3. Before
you move on, take a few minutes to make sure you are familiar with a few concepts that are essential
to Leviton’s Centura system.
INTRODUCINGTHE CENTURA COMPONENTS
Centura consists of a number of components that can be mixed
and matched to create a lighting system with tailored levels of
automation and user control. Every Centura system must
incorporate the CN100 Centura Dimming Power Pack (Figure 1-1),
which retains all settings and serves as the central link between
peripheral devices. After that, what you choose to incorporate into
your Centura System is up to you. It may vary from room to room
depending on: the needs of the user, if it has windows or not,
existing occupancy patterns, real-life safety issues, and a number
of other variables.

SYSTEM OVERVIEW • DEFINITIONS
Light Maintain Level
The level of light that the photocell
measures and that the Centura
System will try to constantly
maintain when using the
daylight-harvesting feature.
This light level should be set to
the optimal level for a specific
user in a specific area of a room.
Occupancy Sensing
Motion sensors that monitor
a space and turn lights off after
everyone leaves and on again
when someone returns.
Automatic light switching is
hands-free and provides users
with top convenience. Occupancy
sensors can provide considerable
energy savings by ensuring that
lights are not left on by mistake.
Address & Address Set
Within the Centura System, an address
is a unique label that groups Centura devices together so that specific controllers
and Personal Dimmer locations control specific fluorescent fixtures.The Address
Set refers to all the components that are grouped together under one address.

KEY CENTURA DEFINITIONS
Leviton's Centura Fluorescent Dimming & Energy Management System is a more comprehensive
system than you may be used to. In order to understand Centura, you should understand a few, key
concepts and terms.
Daylight Harvesting
Using surrounding ambient (often natural) light to supplement artificial light in order to keep a constant
lighting level while saving electricity. Within the Centura System, daylight harvesting requires connecting
the CN100 Power Pack directly to an ODC0P photocell, light fixtures, and a dimming controller and/or
software and SmartJack combination.

SYSTEM OVERVIEW • SENSOR COMBINATIONS
HOW DIFFERENT SENSOR COMBINATIONS OPERATE
Because the Centura System is a combination of components that may vary from installation to
installation, as well as from room to room, how it works is dependent on which components are
selected.The two components that have the greatest impact are the photocell and the occupancy
sensors, as you can see by the examples below.The devices or methods you choose for interfacing
with the system in a particular room are more a matter of preference (for example, using a computer
or a traditional switch) and have little effect on how lighting will function.
Keep in mind that you can have a number of different setups for different address sets within a
single installation. For example, Address Set A may be for a cafeteria and may have a photocell
but no occupancy sensors, while Address Set B may be located in a private office and incorporate
both components.
Also note that the system may not behave as described when overriding Emergency, Service Switch,
or Time Clock inputs are active.
•When in Emergency Mode, lights will remain on at full brightness.
•When the Service Switch is activated, lights will stay off so maintenance and repairs on lighting can
take place.
•When a Time Clock setting is active, lighting behavior may be dictated by company-wide settings.
These scheduled lights off occurrences can be overridden by manual switching or occupancy
detection.
Photocell Only
In general, the photocell will help keep an area lit at the same approximate level (Light Maintain Level) at
all times with automatic dimming and brightening. Although the light fixtures themselves may dim and
brighten, depending on how much natural and artificial ambient light is coming into a room, there will be
little, if any, perceptible difference in the level of lighting. Lighting adjustments to maintain the desired
light level will happen automatically but may be overridden by manual adjustments if certain tasks
require different lighting.You may notice that 30 minutes after you’ve manually adjusted the lights to a
brighter level, they will return to the Light Maintain Level by themselves. Environmental regulations in
some states require this override.
Note:The photocell measures light in a relatively finite area: a 60ºpattern from itself.The system will
adjust lighting levels based on the measurement of light within that area alone, so lighting levels
may vary in different areas within an irregularly-shaped or extra large room. Placing additional,
separately controlled lamps or fixtures in certain areas can compensate for these conditions.
Occupancy Sensors Only
If you’ve got an occupancy sensor (or several sensors) in an area, the lights should immediately turn on
to the last brightness setting when someone enters the empty room, and automatically off again after
everyone leaves it.The period of time it takes for lights to turn off can be seconds or minutes, depending
on occupancy patterns, user-configurable settings, and model number.

SYSTEM OVERVIEW • SENSOR COMBINATIONS
Photocell PLUS Occupancy Sensor
The combination of both types of sensors automates on/off switching and dim/bright fluorescent
lighting adjustments.
What to Expect as You Enter the Room
When you enter an empty room, the lights will turn on to the Light Maintain Level or the level the lighting
was manually set to at the time the lights were turned off if that level was lower than the Light Maintain
Level.The lights will remain off if sunlight or other artificial light is enough, by itself, to meet the Light
Maintain Level.
What to Expect while You’re in the Room
As you remain in the room, the lighting level should appear constant even when outside or indoor
ambient lighting conditions change throughout the day because Centura will automatically dim and
brighten the lights, so you won’t have to.This means it won’t get too dark in the room because it’s cloudy
outside or too bright because it’s extremely sunny.
What to Expect whenYou Leave the Room
When everyone leaves the room, the lights will turn off after a period of seconds or minutes—depending
on model, occupancy patterns, and/or manual settings.
Without Either Component
Without either the photocell or occupancy sensor, the Centura System will function as a dimming system
that although, not automated, provides a number of different manual control options—including lighting
adjustments via computer and a hand-held remote control.

BASIC LIGHTING CONTROL • BASIC CENTURA SETTINGS
Chapter 2: Basic Lighting Control
Centura offers a number of different methods for adjusting lighting levels and settings.The most
traditional method is, of course, using wall-mounted switches or controllers and Leviton provides three
options.The CN221 and CN220 are designer-style Decora rocker switches, while the CN200 is a
pushbutton entry pad with an infrared receiver for use with the next option: the NE200 remote control.
Finally, the Leviton Personal Dimmer is a familiar Windows-like graphical user interface that enables you
to adjust light levels and basic settings, and turn lights on and off from your computer.
BASIC CENTURA SETTINGS
Although basic lighting control needs no explanation, you may not be familiar with the terminology we
use to describe each certain setting or why you might want to adjust each setting.
Light Maintain Level
The level of light that the Photocell measures and that the Centura System will try to constantly maintain
within a daylight harvesting system.
Maximum Light Level
The maximum Power Pack output is adjustable between 60% and 100% of the maximum ballast output.
By setting a maximum light level under 100%, you may be able to realize energy savings without
impacting the perceived brightness in an area. For example, lights set at 90% may not appear any less
bright than at 100% output.
Minimum Light Level
The minimum Power Pack output is adjustable between 0% and 40%, which is greater than the minimum
ballast output.The ability to adjust this level can be very useful because some ballasts are not reliable at
the lowest dim levels, causing light bulbs to flicker.*
Preset Light Levels
The four brightness levels that the remote can store and select. Setting Preset Light Levels allows you to
adjust lighting to an exact level by pressing a single button on the remote.This is especially useful where
repeated tasks require specific levels of lighting.
Unoccupied State
Any time the occupancy sensor detects an absence of motion, it can either turn the lights off or dim
them to the Minimum Light Level, depending on the status of this setting.You might want lights to stay
on at a low level when an area is empty as a safety measure or as a theft deterrent.
*This value represents the Power Pack output, not the ballast minimum light output.
