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
fl
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
ff
.
• 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 min-
utes 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_IN-
TERVAL_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.

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.
