Remote sensor placement in different under-
floor heating systems
Embedding in concrete
Before applying the concrete or screed, a con-
duit is positioned approximately 2 metres into
the room. The end of the conduit must terminate
centrally between two floor heating pipes. Seal
the end of the conduit with tape or similar so that
concrete cannot enter it. Try to position the con-
duit as high as possible in the structure, as this
will result in a more representative performance
when controlling the floor surface temperature.
Insert the remote sensor in the conduit before ap-
plying concrete or screed and connect to the ther-
mostat as described above.
LK HeatFloor 22, LK EPS 30/50/70 or
LK Silencio
Cut a slot in the upper side of the slotted board, do
not cross the floor heating pipes. Position a con-
duit in the cut slot, terminate the conduit centrally
between two heat distribution plates. Insert the re-
mote sensor in the conduit before laying the floor
and connect to the thermostat as described above.
Underfloor heating in secondary spaced boarding
Position a conduit between two heat distribu-
tion plates and secure the conduit in the edge
of the secondary spaced boarding using conduit
clamps. Insert the remote sensor in the conduit
before laying the floor and connect to the thermo-
stat as described above.

Position a conduit along the long side of the floor
heating installation so that it is pointing towards
the nearest short side. At the short side cut a jack
approximately 1 metres long in the EPS board
measured from the short side. Insert the remote
sensor in the conduit before laying the floor and
connect to the thermostat as described above.
LK Clip Rail 8/LK Clip Rail 12
Position a conduit along the long side of the floor
heating installation so that it is pointing towards
the nearest short side. At the short side, route the
conduit in the centre between two floor heating
pipes and connect as approximately 1 metres in.
Seal the end of the conduit with tape or similar
so that concrete/flooring compound cannot enter
it. Insert the remote sensor in the conduit before
applying concrete or screed and connect to the
thermostat as described above.

Battery replacement

LK Room Thermostat RF ICS.2 comes with three
1.5V batteries LR03 (AAA). The batteries have a
life expectancy of about two years. However, the
life expectancy is affected by the user's selections,
such as enabled backlight. The room thermostat
display has a battery icon showing the status of
the battery. The battery should be replaced when
the icon is only showing one segment to the right
of the icon.
Change the battery as follows:
Remove the room thermostat from the wall by
gently pushing the locking tab with a screwdriver
while you detach the room thermostat from the
back plate. (The locking tab is positioned on the
underside of the room thermostat.) Replace the
batteries and snap the room thermostat in place
again. After completing the battery replacement,
the room thermostat automatically returns to
normal operation after a short synchronisation.
