Data Sheet

living connect®, Z-Wave Certified Electronic Ra­diator Thermostat

Application

This documents provides information about the
Z-Wave commands supported by living connect®
and guidelines on the implementation of Z-Wave
controllers as well as general description of the

living connect® and how to mount it on a radiator.

living connect® is a electronic radiator thermostat.

It can be controlled by either a Danfoss LinkTM CC
(Central Controller) or a Z-Wave certified control­ler.

(For control by Danfos LinkTM CC see separate da­ta sheet)

living connect® uses Z-Wave wireless communica­tion technology, is easy to install and is supplied
with adapters for all thermostatic valves manu­factured by Danfoss and most other radiator
valve manufacturers.

living connect® is battery powered, compact and
very easy to operate with only three buttons on
the front.

The temperature can be changed at any time us­ing the buttons on living connect®. The change is
transmitted directly to the controller, which can
synchronize the other electronic radiator thermo­stats in the same room. living connect® features
an open-window function, which closes the valve
if the temperature in the room is falling dramati­cally. Main features in a system with the control­ler:

Marking

Installation

living connect® is supplied with adapters for
Danfoss RA valves and valves with M30X1.5
(K) connections (code no. 014G0002), two al­kaline AA batteries and a 2 mm Allen key.

Inserting the batteries

Remove the battery cover and insert the two
batteries. Ensure that the batteries are cor­rectly inserted. A capital "M" must flash on the
display before installation.

RA K

Start by mounting the adapter.

▪

Tighten the RA adapter using the Allen

▪

key. Tighten the K adapter by hand (max.
5 Nm).

Screw the thermostat onto the adapter

▪

and hand-tighten (max. 5 Nm).

2 mm Allen key

Press and hold for approx. 3 seconds

▪

to fix the thermostat.

Connecting living connect®
to a Z-Wave controller

In Z-Wave connecting a device is called “Inclusion” or “Learn mode”.

To connect living connect® to a Z-Wave controller then:

Ensure living connect® is factory reset as explained in the user manual.

▪

Activate "Inclusion" on the Z-Wave controller.

▪

Quickly press and release the select button on living connect®.

▪

Observe both controller and living connect® for status of the process.

▪

Technical requirements:

After a succesful "Inclusion" the controller must send a WAKE_UP_INTERVAL_SET command to

▪

living connect® in order to specify where and when living connect® should communicate wire­lessly.

After sending the WAKE_UP_INTERVAL_SET command, the controller must assign return routes,

▪

so living connect® can reach its destination i.e. the nodeID set in the WAKE_UP_INTERVAL_SET
command.

living connect® will not commence its periodic communications if it is in "Installation mode". "In-

▪

stallation mode" is for physical installation and should not be confused with "Inclusion". Please
consult the user manual of living connect® for instructions on how to leave "Installation mode".

A Z-Wave controller will have access to all living connect® features, which are exposed using

▪

standard Z-Wave command classes.

See other section of this document for more information.

Disconnecting living con­nect® from a Z-Wave con-

troller

Activate special awake
mode on living connect®

In Z-Wave disconnecting a device is called “Exclusion”.

To disconnect living connect® from a Z-Wave controller then:

Activate "Exclusion" on the Z-Wave controller.

▪

Quickly press and release the select button on living connect®.

▪

Observe both controller and living connect® for status of the process.

▪

living connect® will turn on radio communication for short periods of time at specific intervals in or­der to communicate with its controller, unless such a controller has yet to be configured. When radio
communication is not needed by living connect® it will turn the radio off to conserve battery life.

If a user needs to configure a controller for living connect® or send more information to living con-

nect® then the user can activate a special 5 seconds awake mode by pressing the select button on
living connect®.

Important

living connect® and Z­Wave repeaters

Implemented Z-Wave de­vice classes

The nodeID set in the WAKE_UP_INTERVAL_SET command must be for a permanently listening

▪

device which reponds to the commands sent from living connect®. This means PC's with USB
sticks will only work if the PC is never turned off. If the controller is turned off for extended peri­odes, living connect® will use the batteries too fast.

To preserve battery - Wake_Up_intervals should not be set to less than 5 min. Increasing the

▪

time between intervals will increase battery life but can reduce user satisfaction due to long re­action times.

Although living connect® supports single commands, multi commands must always be used to

▪

ensure two years battery lifetime.
If multiple thermostats are installed in the same room it is important that the controller ensures

▪

that they all have the same schedule and the same setpoint.
In order to ensure proper routing with battery operated devices, the controller must support

▪

SUC.

living connect® may benefit if more mains powered Z-Wave devices are added to a Z-Wave network.

Mains powered Z-Wave devices improve the reliability of a Z-Wave network as they can act as re­peaters and thus provide alternate routes for communication.
