Load Shedding (Demand Response); Building Management System (Bms) Interface - Crestron iLux CLS-C6 Series Operation Manual

Crestron CLS-C6/C6M & CLSI-C6/C6M
Operations Guide – DOC. 6347E
When the Override mode is disengaged, all loads revert to their previous values.
While in Override mode, all slave units are placed into Override mode as well,
regardless of the room combining status.
While in Override mode, all Cresnet commands (whether sent by a control
processor, or by a master iLux to a slave) shall be ignored, except for load level
commands, which cause the new final value to be stored and thus recalled when the
unit exits Override mode.
Override mode levels take precedence over any limits set by Load Shed mode.

Load Shedding (Demand Response)

The iLux can enter a Load Shed mode via an external input (such as into a DIN-IO8
or GLS-SIM).
When entering Load Shed mode, any loads that must have their levels reduced shall
do so with a 1/2-second fade.
While in Load Shed mode, all loads must always be kept at or below their load shed
level (the only exception being Override mode).
When exiting Load Shed mode, loads that were commanded to go to a level below
their load shed level shall fade to the originally desired level in 1/2 seconds.
While in Load Shed mode, the 7-segment display shall flash "LS" at a rate of 1
second on, 1 second off, unless the display is actively showing something else.
Using iLux Designer, any value can be entered into the Load Shed Max field (0-
100%). The default Load Shed Max value in iLux Designer is 80% for all loads.

Building Management System (BMS) Interface

A DIN-IO8 unit is supported for the purpose of providing a contact-closure interface
to a Building Management System. A GLS-SIM is supported for the purpose of a
very basic contact-closure interface to a Building Management System.
The DIN-IO8 is required to have a designated Cresnet ID in order to work properly
in this capacity. The designated addresses are 0xD0 for normally open and 0xD1 for
normally closed DIN-IO8 types.
The functionality of the DIN-IO8 and/or GLS-SIM is fixed and cannot be changed
via Setup mode or iLux Designer.
The functionality provided by the DIN-IO8 is as shown in the following table:
DIN-IO8 BMS Functionality
PORT
1 Recall On Scene (edge-triggered)
2 Recall Off Scene (edge-triggered)
3 Recall Scene 14 (edge-triggered)
4 Recall Scene 15 (edge-triggered)
5 Override Mode (level-triggered)
6 Load Shed Mode (level-triggered)
7 Defeat Occupancy. Sensors (level-triggered)
8 Lockout Front Controls (level-triggered)
Four unique Cresnet IDs are defined for the GLS-SIM to allow this unit access to the
following functions (2 per ID):·
• Unit 1 (Cresnet ID 0xC5): Recall On/Off scene
