Z-Wave Setting

Include into Z-Wave network
Under the normal working interface, long press the” A “and” V ” buttons synchronously for 3sec, and the device will enter the Z-WAVE MENU interface, long press the” A “and” V” buttons synchronously for 3sec again or without any operation for 10sec, it will back to the homepage. Before the device is included in the network,”- – -” will display on the screen. Then shortly press the” A” button, the device will enter learning mode to get a node ID. If inclusion is a success, a node ID will display on the screen in a few seconds. Note: A node ID can always inform us whether the device is in the network or not.

Exclude from Z-Wave network
Under the normal working interface, long press the” A “and” V ” buttons synchronously for 3sec, and the device will enter the Z-WAVE MENU interface, long press the” A “and” V” buttons synchronously for 3sec again or without any operation for 10sec, it will back to the homepage. Current ID displays on the screen, short press the” A” button, and the device will enter learning mode, current ID will flash, once “- – -” is displayed on the screen, the device has excluded from the Z-Wave network.
