Vendor Name: Lutron Electronics Co., Inc.
Product Name: myRoom BACnet Integration
Applications Software Version: 2.0
Firmware Revision: 3.3

Product Description
BACnet IP is embedded in the myRoom processor. There are two types of BACnet devices available in myRoom:
subsystem devices and area devices. The subsystem devices are main BACnet devices; typically, one main device
per guestroom of the building. The area devices are virtual BACnet devices of the subsystem device, typically one
per guestroom of the building. It is normal to have multiple subsystem main devices and area virtual devices
in a project.

Notes: The Area Name is the logical name that typically corresponds to a physical location in a building. The Instance is the same as the
unique Device ID assigned to each area.
Lighting Level AV 2 X X X % 0 100
Notes: The intensity level of all lighting fixtures in the area. The lighting level will be an analog value between 0% and 100%. If the lighting
fixtures in the area are at different light levels, this value will be set to the level of the highest intensity in that area. Does not include
RF zones.
Lighting State BV 3 X X X 0 1 Off On
Notes: The lighting state will be ON if any of the lighting fixtures in the area are in the On state; if all lighting fixtures are off, the lighting
state will be set to OFF.
Lighting Scene MSV 4 X X X 1 Number
of scenes
defined
for this
area
{SceneName}
Notes: The lighting preset to which the lighting fixtures in that area are currently set. If the value is set to 1, the Off Scene will be selected,
which will turn all lights to OFF. All other scenes are defined within the Lutron system configuration software. If lights are currently
not set to a valid lighting scene, then the value will be set to an unknown preset level.
Occupancy State MSV 8 X X 1 4 1 = Unoccupied
2 = Occupied
4 = Unknown
Notes: A read-only property that indicates the occupancy of physical sensors in a guestroom area. Occupied means that at least one sensor
in the area is indicating Occupancy. Unoccupied means that all of the sensors in the area are indicating Unoccupied. Unknown means
that not all of the sensors in the area have reported their status. The myRoom system uses Guest Presence Detection (GPD) to
determine the overall occupancy of the guest room and reports this via a state variable. See the myRoom main device BACnet PIC
statement (P/N 3691088 at www.lutron.com) for details.
Number of Lamp
Failures
AV 15 X X 0 none
Notes: For all digitally-controlled EcoSystem or DALI® fluorescent ballasts and LED drivers controlled by a DIN power module, the number of
ballasts with lamp failures in the area will be displayed. If the value is 0, there are no lamp failures for the area.
Number of Devices
Not Responding
AV 16 X X 0 none
Notes: For any QS device, EcoSystem or DALI® digital fluorescent ballast or LED drivers controlled by a DIN power module, the number of
devices that are programmed into the system but are not responding will be displayed. If the value is 0, there are no device failures
for the area.
Total Lighting
Power
AV 18 X X watts 0 none
Notes: A calculated value that indicates the total instantaneous power consumption for all of the lighting loads in the area.
Maximum Lighting
Power
AV 19 X X watts 0 none
Notes: The maximum connected lighting load of the area. This value is the maximum value that Total Power can achieve. Maximum Power
minus Total Power equals the power being saved. Typically, this value does not change.

Notes: If a wireless input (e.g., occupancy sensor) that is connected to the system is no longer communicating with the Lutron system, the
device output will be greater than 0. The value will be equal to the number of failures in the area. This could be because of battery
failure, the device being out of range of the QSM, or device failure. If the value equals 0, all wireless inputs in the area are reporting
properly.

Notes: The light level intensity of a specific zone of lighting within an area. The light level will be an analog value between 0% and 100%.
There can be multiple lighting zones defined within each area. Each lighting fixture in the area will be assigned to one, and only one,
lighting zone. Each will have a unique instance ID from 1000 to 1999. RF zone controls are not included.
{ShadeGroupName}
Level
AV 2000 to
2999
X X X % 0 100
Notes: The shade level of a specific shade group of Lutron Sivoia QS shades within an area. The shade level will be an analog value between
0% and 100%. 100% equals fully open; 0% equals fully closed. There can be multiple shade groups within each area; each group will
have a unique instance ID from 2000 to 2999.
