	7	+Crestron Zūm Wired is a distributed lighting control system that has various global and local control options. Zūm Wired uses industry standard dimming protocols (DALI, 0-10V, and phase dimming) and advanced sensors to provide automated control of a building or facility's lighting. With certain designs, it is also possible to integrate control over DMX fixtures, building management systems, and other third-party devices (such as motorized shades and HVAC).

	13	+Zūm Wired systems consist of ZUMNET-JBOX-* room controllers and a number of connected ZUMLINK-* devices. ZUMLINK-* devices can be ZUMLINK-JBOX-* load controllers, ZUMLINK-OCC-* presence detectors, or ZUMLINK-KP-R-W keypads (wall switches). ZUMNET-JBOX-* and ZUMLINK-JBOX-* devices have additional inputs for third-party presence detectors, 0-10V analog photocells, and contact-closure local override.

	30	+ZUMNET-JBOX-* devices can be set to be either the Primary room controller or a Secondary load controller. There must only be one Primary ZUMNET-JBOX on a given Zūm Link bus, and in a networked system the Primary ZUMNET-JBOX is the one that should be connected to the Zūm Net.

	32	+* In Primary mode, the ZUMNET-JBOX acts as the Zūm Link host, and is able to detect all connected Zūm Link devices. If connected to in Crestron Toolbox, a Primary ZUMNET-JBOX can be used to view and manually address any connected ZUMLINK-* devices. While in App mode, a ZUMNET-JBOX in Primary mode is the logical room controller for the space and is the device that should be used for configuration via the Zūm App.
	33	+* In Secondary mode, the ZUMNET-JBOX acts as if it were a ZUMLINK-JBOX. It does not process any room control logic, and when connected to via Crestron Toolbox it will not be able to see any other ZUMLINK-* devices. Using Secondary mode is rare, and should only be used in cases where a spare ZUMNET-JBOX is being used to add a load to another ZUMNET-JBOX or replace a ZUMLINK-JBOX that has been lost or damaged.

40		-Designs for Zūm Wired systems can be broadly described as being either "standalone" or "networked". Both standalone and networked applications will be designed to have at least one ZUNET-JBOX-* per room with a number of connected ZUMLINK-* devices.

	43	+Designs for Zūm Wired systems are broadly categorized as either "standalone" or "networked" designs. Both standalone and networked systems should be designed with one ZUMNET-JBOX-* per room or logical control space connected to a number of ZUMLINK-* devices within that same space. In networked systems, there is also a control processor which provides centralized control of the entire system. ZUMNET-JBOX-* must be daisy-chained together with Zūm Net and then connected back to the processor. In standalone applications, there is no processor and no Zūm Net cabling connecting different rooms to each other.
