Quickstart

This is a Z-Wave Device for Europe. To run this device please connect it to your mains power supply.

Important safety information

Please read this manual carefully. Failure to follow the recommendations in this manual may be dangerous or may violate the law. The manufacturer, importer, distributor and seller shall not be liable for any loss or damage resulting from failure to comply with the instructions in this manual or any other material. Use this equipment only for its intended purpose. Follow the disposal instructions. Do not dispose of electronic equipment or batteries in a fire or near open heat sources.

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 a 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 Z-Wave 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.

Product Description

This unit allows the control of the heat dissipation on a heating radiator. With the local manual control the user presets the convenience temperature on a scale between one (16°C) and five (28°C) and anti-freeze protection like on any other conventional thermostatic radiator valve. It will be included and controlled in a Z-Wave network by a remote control, a wireless control centre or any other kind of Z-Wave controller including a PC-software. Via Z-Wave the TRV can be turned into an energy saving mode, where the room temperature is regulated to about 3…4K lower than in convenience mode. This is the recommended temperature difference used to save energy while protecting the room climate. An indicator on top of the device shows the mode. A sun-icon indicates convenience mode, moon-icon indicates the energy saving mode. Since the normal regulation of the temperature is done mechanically like in conventional TRV&rsquos and only the switching between convenience and energy saving move is done with a motor consuming electrical energy, the battery lasts for up to four heating periods.
To enable energy saving even when the central Z-Wave wireless control is not available the device can be preset with up to four different heating times per day. Once programmed it will change the heating mode without any further interaction. Preset heating modes can always be overwritten either manually on the device or wirelessly with an overwrite command.

There are multiple connection systems to the wall radiator. Please check the documentation of Danfoss to find out which system fits to your needs. We offer the two most common systems RA 2000 and RA/K. Other connection types are on request."

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 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.

Quick trouble shooting

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

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

Explanation of Z-Wave specific terms

Controller — is a Z-Wave device with capabilities to manage the network. Controllers are typically Gateways,Remote Controls or battery operated wall controllers.
Slave — is a Z-Wave device without capabilities to manage the network. Slaves can be sensors, actuators and even remote controls.
Primary Controller — is the central organizer of the network. It must be a controller. There can be only one primary controller in a Z-Wave network.
Inclusion — is the process of adding new Z-Wave devices into a network.
Exclusion — is the process of removing Z-Wave devices from the network.
Association — is a control relationship between a controlling device and a controlled device.
Wakeup Notification — is a special wireless message issued by a Z-Wave device to announces that is able to communicate.
Node Information Frame — is a special wireless message issued by a Z-Wave device to announce its capabilities and functions.
