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.

For more information about Z-Wave technology, devices, white papers etc. please refer to www.z-wave.info.

Product Description

This device is a Z-Wave controlled electronic radiator thermostat. It is mounted on wall heating valves and controls them by a motor. The device accepts a setpoint that is either set manually using buttons on the device or wirelessly using Z-Wave. Afterwards, the device will regulate the warm water supply to the wall radiator and compare the detected temperature to ensure, that the temperature in the room is kept at the desired level. A small LCD panel on the device displays the setpoint temperature on request.   Beside setting a desired temperature the device will support special heating schemes, such as energy saving and frost protection and intelligent functions like a valve training function to ensure that valves are still operational after longer periods. The Popp radiator thermostat can be mounted to valves with standard M30x1.5 connector or RA2000. Opposite to the Danfoss TRV this device will report the room temperature as detected and calculated by the device’s temperature sensor.

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 the batteries and keep the function button "*" pressed for 5 seconds after the batteries are inserted back.

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.


Adjustment to the radiator

The device can be adjusted to the room size. Three room sizes are known. The factory setting is P2. Use P1 if the radiator appears oversized for the room. Use P3 if it is undersized. To change the assumed room size press (p) for 3 seconds to enter management mode (M in display). Press (v) until a "P" is displayed in the LCD display. Hit the (o) button. Now select 1, 2 or 3 using the arrow keys and exit with (o).


To remove the thermostat, insert an appropriate tool in the hole in the thermostat"s battery chamber (see illustration). Keeping the tool in position, turn the entire thermostat anticlockwise until it is completely unscrewed.

Adjusting to the valve

During the first night of operation TRV will shut off the radiator heat and then open again to detect the exact opening point of the valve. This will allow TRV to control the heat as efficiently as possible. If necessary, the procedure is repeated once a night for up to a week. You might experience the valve being warm during the adjustment procedure, regardless of the room temperature.

Intelligent Control (Forecast)

During the first week of operation TRV learns when it is necessary to start heating the room in order to reach the correct temperature at the correct time. The intelligent control will continuously adjust the heating time compared to seasonal temperature changes.


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.


Click on the middle button will confirm inclusion or exclusion and wakeup the device for wireless communication. A long push for 3 seconds on the middle buttons enters and leaves the management mode indicated by a "M".

Product Usage

The TRV is operated by wireless commands from a Z-Wave controller. 

The actual temperature setpoint is shown in the LCD display and can be overwritten by using the arrow keys on the device. This overwriting is temporary and only valid until the next change of the temperature setpoint (either triggered from external wireless command or from the internal downloaded schedule) becomes active.

The actual measured ambient temperature is not shown on the LCD display but is reported to the central gateway. 

The device will also recognize an open window (sudden temperature drop within short period of time) and turn down the heat for 30 minutes to save energy.

Local LCD Display

The local LCD display gives information about the status of the device

Link Test

The Thermostat allows to check the link quality to the controller device. Press the middle button (o) for 3 seconds until M is displayed. Select "LI" in display using the arrow keys, then confirm the link test with the middle button. A blinking antenna symbol indicates the link test. If the antenna symbol keeps flashing after about 3 seconds there is a problem with the wireless connection. If the antenna symbol stops flashing, the link quality is sufficient. A successfull link test will also terminate the exception mode described below.

The device applies multiple technologies to extend battery life. It is combining multi commands to a single command and adapt its behavior to the capabilities of the network controller. Make sure to use Danfoss Living connects only with Z-Wave controllers fully implementing all battery life time extention methods recommended by Danfoss. All controllers based on Z-Wave.Me software (e.g. RaZberry) fully support these methods.

When the battery level is low, the alarm bell icon flashes and the display will flash 8 times an hour between 19 and 22 hrs. If the battery goes flat, the system switches automatically to frost protection mode.

Node Information Frame

The Node Information Frame (NIF) is the business card of a Z-Wave device. It contains information about the device type and the technical capabilities. The inclusion and exclusion of the device is confirmed by sending out a Node Information Frame. Beside this it may be needed for certain network operations to send out a Node Information Frame. To issue a NIF execute the following action: Clicking the function button

Communication to a Sleeping device (Wakeup)

This device is battery operated and turned into deep sleep state most of the time to save battery life time. Communication with the device is limited. In order to communicate with the device, a static controller C is needed in the network. This controller will maintain a mailbox for the battery operated devices and store commands that can not be received during deep sleep state. Without such a controller, communication may become impossible and/or the battery life time is significantly decreased.

This device will wakeup regularly and announce the wakeup state by sending out a so called Wakeup Notification. The controller can then empty the mailbox. Therefore, the device needs to be configured with the desired wakeup interval and the node ID of the controller. If the device was included by a static controller this controller will usually perform all necessary configurations. The wakeup interval is a tradeoff between maximal battery life time and the desired responses of the device. To wakeup the device please perform the following action: Clicking the function button "*"

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

Local Protection

The device can be turn into a child protection mode. In this mode all local operation is disabled. The protection mode is controlled wirelessly. However there is a sequence to overwrite a protection state and to temporary enable local operation: The protection can not be overwritten locally.
