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

Living Connect 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.

The device has an internal scheduler, that allows to define up to 9 setpoints for up to 7 week days. Once programmed, these setpoints will be activated without any further manual or wireless interaction. Beside setting a desired temperature the device will support special heating schemes, such as energy saving and frost protection and intelligent functions such as detection of open windows or a valve training function to ensure that valves are still operational after longer periods.

The living connect can be mounted to valves with standard M30x1.5 connector or RA2000 (Danfoss snap in).

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 battery cover and take out one battery. Press and hold the (o) button for about 10 secs while reinserting the battery. The device will go into management mode.

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

Installation

Adjustment to the radiator

The device can be adjusted to the room size. Three room sizes are known. The default size is P1. 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).

Removal

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.

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

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”.

Exclusion

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 Danfoss device is operated by wireless commands from a Z-Wave controller. It is operated in two different modes:

• Direct setting of Temperature Set Point by Controller. (Attention: There may be a delay in execution of a setpoint command due to the wakeup interval of the device. If the setpoint is to be changed at e.g. 16.00 and the wakeup interval is 15 minutes, make sure to send the command latest at 15.45)
• Downloading of a whole weekly schedule into the device that will then regulate the heat independent of the controller. The device is capable holding a complete schedule with up to 9 different setpoints for each individual week day. The device will calculate the best time to start heating up or heating down.

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 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.

_ Known Problems in Z-Wave Networks : This device is sleeping and wakes up regularly. When waking up the device needs a wireless connection to the controller to get clock and heating schedule updates if needed. If no wireless connection to the controller can be found the device will enter an exception mode indicated by a flashing bell in conjunction with flashing antenna symbol on the LCD display. To exit this exception mode as soon as possible the device tries to reestablish a wireless connection by applying the so-called “Lost” procedure defined by Z-Wave with the help of a Static Update Controller (SUC) in the network. In case of success the execption mode is terminated. In case of failure – e.g. because the controller is still shut off – the device will remain in the exception mode and repeats the “Lost” process. This drains the battery very fast. To avoid this situation make sure the following requirements are made: (a) the thermostat has a stable direct wireless connection to the controller or (b) there is a static controller serving as SUC in the Z-Wave network and there is a valid route between the device and this SUC._

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:

Click on the middle button will send out a Node Information Frame (if not in exception mode).

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:

Click on the middle button will wakeup the device for wireless communication (if not in exception mode).

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.
