A Z-Wave portable primary controller is a device that you need to install (or remove) Z-Wave devices as “nodes” on a Z-Wave network. Internally, it maintains the network management for the network, including all available node ID (addressing) information.

As a portable device, you carry the primary controller around the jobsite, such that you can key in an operation (such as adding a node) while physically next to that device. Most Z-Wave devices have a button or switch that you press to coordinate this operation from the “slave” side.

Z-Wave primary controllers also typically allow you to engineer other facets of a Z-Wave network too, such as adding “groups” and “scenes”. However, it is usually faster and simpler to do this from the Niagara station interface to the Z-Wave network.
