Sequence of Operations – Embedded OpenADR
The following is the communication path between OpenADR VTN server and nLight networked devices:
1. The nECY receives a DR event signal from the OpenADR VTN server.
2. The nECY invokes the appropriate "Automated DR Level" setting in nLight devices connected to it which corresponds
to the severity of the event indicated in the DR signal.
3. Each nLight device is capped at its individual Automated DR Level setting; distributed control algorithms within each
device are capable of controlling light levels below the Automated DR Level setting (e.g., in response to daylight, occu-
pancy, or manual wall controls) but they cannot exceed this maximum output level.
4. At the end of the event, the Automated DR Level is released by the nECY allowing networked devices to output light
levels up to their normal High Trim setting.
The Automated DR Levels can be configured for specific luminaires, devices or zones using SensorView software interface.
Networked control devices supporting ECLYPSE Embedded OpenADR have ADR settings enabled out-of-box with the
£
following default settings (can be changed during system startup):
– Automated Demand Response: Enabled
– Automated Demand Response Low Level: 90% max light output
– Automated Demand Response Medium Level: 80% max light output
– Automated Demand Response Max Level: 70% max light output
Automated DR Level settings are individually configurable for specific luminaires, devices, or zones.
£
– Light outputs of 100% to 1% (in 1% increments) and "Off" can be configured for each severity level of Automated
DR.
– Luminaires can be enabled or disabled to respond to ADR events invoked by the nECY.
The nECY can issue a Test Event to demonstrate DR commissioning to the owner and/or commissioning agent.

The Automated DR Levels can be configured for specific luminaires, devices or zones using the SensorView software in-
terface.
Application Requirements
The utility VTN server must support OpenADR 2.0a VEN clients.
The nECY must have an outbound https connection to the OpenADR VTN IP address (TCP 443).
