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

The varmo TZ eco radiator valve regulates your radiator with energy-saving Z-Wave wireless standard. Thus, you can add a component to your Z-Wave Smart Home network.Thanks to the FLiRS (Frequently Listening Receiver Slave), the heating valve responds to incoming commands without any major delays, for example changing the temperature.Design covers are available in various colors, so you can change them according to your wishes and interior design.The varmo TZ eco radiator valve is easy to operate, has an orange backlit display and an extra large temperature display. Heating periods are programmable, the daily and weekly times are individually programmable and the valve detects when a window is open. The manual adjustment is of course possible at any time.In addition, the valve has a child safety lock and various security levels, a frost and lime protection function and fits on many common radiator valves.The display can be rotated 180 degrees.

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.

Reset to factory default

This device also allows to be reset without any involvement of a Z-Wave controller. This
procedure should only be used when the primary controller is inoperable.

Remove batteries. Press and hold boost button. While still holding boost button insert batteries. The LCD shows RES. Release boost button. To perform the factory reset press boost button.

Safety Warning for Batteries

The product contains batteries. Please remove the batteries when the device is not used.
Do not mix batteries of different charging level or different brands.

Installation

Mounting the Donexon TZ eco Thermostat

After adding the Donexon TZ eco Thermostat to a network, it is ready to be installed on the radiator. The LCD shows INS. Do not press the boost button yet.

Installation at the radiator without Adapter

Mechanical Installation

Press the boost button to start mechanical installation.

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

Press the Boost-Button.varmo TZ eco will show the assigned Node ID.

Exclusion

Press and hold the boost button of the varmo TZ eco for at least 5 seconds.

Inserting batteries

Remove the battery cover by simply pulling it off. Now insert the batteries. Pay attention to the correct

polarity! At a later battery change, the configuration of your Donexon TZ eco Thermostat is maintained.

Setpoint adjustment

The setpoint is adjusted via plus and minus button.

Altering the setpoint locally will set the Donexon TZ eco Thermostat in heating mode.

The energy saving setpoint can only be adjusted via Z-Wave.

The configurable setpoint range is 8°C to 28°C.

If the setpoint is increased/decreased above/below the set point limits, the

Donexon TZ eco Thermostat will change into boost / off mode.

Child protection

Press and hold plus and minus button simultaneously for 3 seconds to enable/disable the child protection.

If theDonexon TZ eco Thermostat is set into the highest protection level it is no longer possible to operate the device locally.

Altering the operating states

Off-Mode

Press minus button until OFF is displayed.

Boost-Mode

Push the boost button.

Alternatively, press the plus button until ON is displayed.

Heating-Mode

If the operating state is not heating mode, pressing the plus or

minus button will bring the device in heating mode.

Window open detection

If the room temperature drops, the window open detection will trigger.

Donexon TZ eco Thermostat will change temporarily in off mode for 15 minutes.

Window open detection will end automatically after 15 minutes and the previously active

operating mode will be restored.

Window open detection can also be canceled by a button press.

The window open detection is disabled during manufacturer specific mode.

The sensitivity of the window open detection can be configured

Display NodeID

Press and hold the boost button for 3 seconds to display the NodeID.

Quick trouble shooting

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

1. Make sure a device is in factory reset state before including. 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 device to benefit from the meshing

Association – one device controls an other 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 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 case of a two byte value the same logic applies: Values greater than 32768 may
needed to be given as negative values too.

• 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.
