What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This device is suited for use in the region mentioned in the Quickstart section.
Z-Wave ensures reliable communication by reconfirming every message (two-way communication) and every mains-powered node can act as a repeater for other nodes (meshed network) in case the receiver is not in direct wireless range of the transmitter. This device and every other certified Z-Wave device can be used together with any other certified ZWave device regardless of brand and origin as long as both are suited for the same frequency range. If a device supports secure communication it will communicate with other devices secure as long as this device provides the same or a higher level of security. Otherwise, it will automatically turn into a lower level of security to maintain backward compatibility. For more information about Z-Wave technology, devices, white papers, etc. please refer to www.z-wave.info.

Product Description

Prepare for Installation / Reset

Please read the user manual before installing the product. In order to include (add) a Z-Wave device to a network, it must be in the factory default state. Please make sure to reset the device into factory default. You can do this by performing an Exclusion operation as described below in the manual. Every Z-Wave controller is able to perform this operation however it is recommended to use the primary controller of the previous network to make sure the very device is excluded properly from this network.
Safety Warning for Mains Powered Devices
ATTENTION : only authorized technicians under consideration of the country-specific installation guidelines/norms may do works with mains power. Prior to the assembly of the product, the voltage network has to be switched off and ensured against re-switching.

Inclusion/Exclusion

On factory default, the device does not belong to any Z-Wave network. The device needs to be added to an existing wireless network to communicate with the devices of this network. This process is called Inclusion.
Devices can also be removed from a network. This process is called Exclusion. Both processes are initiated by the primary controller of the Z-Wave network. This controller is turned into exclusion respective inclusion mode. Inclusion and Exclusion is then performed doing a special manual action right on the device.
Inclusion
In a normal working interface, press & hold S4 to enter interface for inclusion of Z-Wave network. Before the device is included into the network, “- – -” will display on the screen. Then press S4 once, the device will enter learning mode to get a node ID. If inclusion is successful, a node ID will display on the screen in a few seconds.
Exclusion
In a normal working interface, press & hold S4 to enter interface for exclusion of Z-Wave network. Before the device is excluded into the network, a node id will display on the screen. Then press S4 once, the device will enter learning mode to get a node ID. If inclusion is a success, “- – -” will display on the screen in a few seconds.
Auto-Inclusion
Besides the standard inclusion, these devices support the so-called auto inclusion. Right after powering up the device remains in an inclusion state and can be included by (any) gateway without further actions on the device itself. The auto inclusion mode will time out after some time.

Quick troubleshooting

Here are a few hints for network installation if things dont work as expected.

1. Make sure a device is in a factory reset state before including it. In doubt exclude before include.
2. If inclusion still fails, check if both devices use the same frequency.
3. Remove all dead devices from associations. Otherwise, you will see severe delays.
4. Never use sleeping battery devices without a central controller.
5. Dont poll FLIRS devices.
6. Make sure to have enough mains-powered devices to benefit from the meshing.

Association – one device controls another device

Z-Wave devices control other Z-Wave devices. The relationship between one device controlling another device is called association. In order to control a different device, the controlling device needs to maintain a list of devices that will receive controlling commands. These lists are called association groups and they are always related to certain events (e.g. button pressed, sensor triggers, …). In case the event happens all devices stored in the respective association group will receive the same wireless command, typically a ‘Basic Set’ Command.
Association Groups:

Configuration Parameters

Z-Wave products are supposed to work out of the box after inclusion, however, certain configuration can adapt the function better to user needs or unlock further enhanced features.
IMPORTANT: Controllers may only allow configuring signed values. In order to set values in the range 128 … 255 the value sent in the application shall be the desired value minus 256. For example: To set a parameter to 200 it may be needed to set a value of 200 minus 256 = minus 56. In the case of a two-byte value the same logic applies: Values greater than 32768 may be needed to be given as negative values too.
Parameter 1: Upload temperature format automatically
Size: 1 Byte, Default Value: 2

Parameter 2: Upload temperature and humidity automatically
Size: 1 Byte, Default Value: 3

Parameter 3: Upload temperature difference
Size: 2 Byte, Default Value: 5

Parameter 4: Upload time interval regularly
Size: 2 Byte, Default Value: 30

Parameter 5: Upload humidity difference
