living connect® Z,
Electronic Radiator Thermostat
Preparation
living connect® Z is an electronic radiator thermostat, intended
for use with water based room radiators. It can be controlled by
a Z-Wave certied controller, which supports the appropriate
command classes.
Z-Wave
controller
living connect® Z
sensor
living connect® Z is supplied with adapters for Danfoss RA valves
and valves with M30 x 1.5 (K) connections, two alkaline AA batteries and a 2 mm Allen key.
Inserting the batteries
Remove the battery cover and insert two AA
batteries. Make sure the batteries are correctly
oriented.
Rechargeable batteries must not be used.
When replacing batteries the programme settings will be preserved, but after two minutes
the settings for time and date are reset.
Including the device to a network
Z-wave
controller
• Ensure living connect® Z is factory reset.
• Activate “Inclusion” on the Z-Wave controller.
• Quickly press and release on living connect® Z.
• Observe both controller and living connect® Z for status of the
process.
Testing the connection
Press for at least 3 seconds until M is displayed.
Press until LI is displayed.
Press to test the connection.
LI disappears when the connection is made.
If no connection can be made, the alarm symbol
and the antenna symbol ashes.
Installing living connect® Z
M must be ashing on the display prior to installing.
1. Start by mounting the appropriate adapter.
2. Tighten RA adapter using the
Allen key, hand-tighten the K
adapter (max. 5 Nm).
3. Screw the thermostat onto
the adapter and tighten by
hand (max. 5 Nm).
4. A large M ashes, press to x the thermostat.

Temperature control and adjustment
The temperature is usually con-trolled via
the controller, but may be changed at any
time using the thermostat’s buttons.
If this is done, the thermostat sends a
message to the controller, which then
syncronises other thermostats in the
same room.

Excluding the device from the network
• Activate “Exclusion” on the Z-Wave controller.
• Quickly press and release on living connect® Z.
• Observe both controller and living connect® Z for status of the
process.
Re-installation mode
If the thermostat has been removed from
the radiator and needs to be reinstalled
(after being used), it is necessary to activate
installation mode to prevent damage to the
thermostat.
To enter installation mode:
• Press until M is displayed.
• Press to withdraw the spindle. M ashes.
• Reinstall the thermostat on the valve.
• Press for approx. 3 seconds to x the thermostat.
If the thermostat is moved to another room, make sure to make
the necessary changes in the controller.
Factory reset
Remove the battery cover and take out one battery. Press and
hold for approx. 5 seconds, while re-inserting the battery.
living connect® Z is now factory reset and in mounting mode.
Wake up
A controller can only communicate with living connect® Z, when
the device is awake. The intervals when the thermostat is awake
can be set using the “wake up command class”.
Press to manually wake up the device. It will stay awake for 10
seconds and send out a node info.

Technical requirements and info
• After a succesful inclusion the controller must send a WAKE_
UP_INTERVAL_SET command to living connect® Z in order to
specify where and when living connect® Z should communicate
wirelessly. If not, the thermostat cannot perform wake ups and
the alarm and antenna symbols will ash.
• 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® Z. This means PC’s with
USB sticks will only work if the PC is never turned o.
• If living connect® Z does not get correct and timely replies (e.g.
if the controller is turned of ) it will automatically switch to 30 minutes wake up intervals. If at next wake up the controller replies
as expected, living connect® Z will switch back to the original
wake up interval.
• After sending the WAKE_UP_INTERVAL_SET command, the
controller must assign return routes, so living connect® Z can
reach its destination, i.e. the no-deID set in the WAKE_UP_INTERVAL_SET command.
• living connect® Z will not commence its periodic communications
if it is in “Mounting mode”. “Mounting mode” is for physical
installation and should not be confused with “Inclusion”. Please
see section “Installing living connect® Z, item 4” for instructions
on how to leave “Mounting mode”.
• Although living connect® Z 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 they all have the same
schedule and the same setpoint.
Troubleshooting
Error code Action
E1, E2, E3, E4 Contact your local Service Technician.
The thermostat is not receiving the expected
replies from the control system.
E5
Check that you have a Z-wave certied
controller running and it has the necessary
functionality to control the thermostat (see
“Technical requirements”).

Safety precautions
The thermostat is not intended for children and must not be
used as a toy.
Do not leave packaging materials where children may be
tempted to play with them, as this is extremely dangerous.
Do not attempt to dismantle the thermostat as it contains no
user-serviceable parts. If error code E1, E2 etc. is shown in the
display or other defects appear, please return the thermostat
to the distributor.
