Z-Wave wireless network
heatapp! radio components communicate with the
heatapp! gateway
using the Z-wave wireless standard.
The Z-Wave radio system is a wireless communication standard specially for use in the smart home sector.
The wireless communication is optimised for low energy consumption and maximum communication safety.
Z-wave uses two-way communication with acknowledgement. Only confirmed telegrams are classed as sent successfully. If a
communication error occurs, the transmit process is repeated three times.
heatapp! floor
,
heatapp! single floor
and
heatapp! repeater
are constantly active in the wireless network and can therefore
serve as Z-Wave routers. Battery operated devices such as
heatapp! drive
and
heatapp! sense
control and
heatapp! sense
are
mainly inactive, only waking periodically to receive and send commands. They cannot be used as routers.
Z-Wave has implemented the feature of a mesh-networking technology in which every mains operated device can send
telegrams to other devices in its own network. The resultant meshed network is controlled by the
heatapp! gateway
and the
routes updated upon changes to the network.

Notes for radio coverage
The radio coverage depends on the building type and the building properties and condition. To achieve good radio coverage, it
may be necessary to use repeaters. Radio coverage can be improved or worsened by changes in the object. As the manufacturer,
we are responsible for the functionality of the goods produced by us. The radio network is set up through the installation and
therefore does not form part of the supplied goods.
If you have questions on the installation, radio and network technology, please contact our technical support or visit our
heatapp! training events.

Radio coverage
Transmitted radio waves have a limited energy which decreases with distance.

Wireless coverage is not the same as wireless range. Wireless is affected by various factors. Radio waves are absorbed, reflected
and attenuated.
