External sensor placement in different under-
floor heating systems
Concrete & screed encapsulated systems
Before applying the concrete or screed, a conduit is
positioned approximately 2 metres into the room.
The end of the conduit must terminate centrally be-
tween two floor heating pipes. Seal the end of the
conduit with tape or similar so that concrete cannot
enter it. Try to position the conduit as high as possi-
ble in the structure, as this will result in a more rep-
resentative performance when controlling the floor
surface temperature. Insert the remote sensor in the
conduit before applying concrete or screed and con-
nect to the thermostat 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 conduit
in the cut slot, terminate the conduit centrally be-
tween two heat distribution plates. Insert the remote
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 distribution
plates and secure the conduit in the edge of the sec-
ondary spaced boarding using conduit clamps. Insert
the remote sensor in the conduit before laying the floor
and connect to the thermostat as described above.
LK EPS 16
Position a conduit along the long side of the floor heat-
ing 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. The conduit is positioned in this jack. Insert the re-
mote 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 con-
nect 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.
Change the battery as follows:
Remove the room thermostat from the wall by
gently pushing the striking plate with a screw-
driver while you detach the room thermostat
from the back plate. (The striking plate is posi-
tioned on the underside of the room thermostat.)
Replace the batteries and snap the room thermo-
stat in place again. After completing the battery
replacement, the room thermostat automatically
returns to normal operation.
