LK HeatFloor 22, LK EPS 30/50/70 or
LK Silencio
Mill a slot on the upper side of the board. Place a
conduit in the slot, end the conduit right between
two heat distribution plates. Take into conside-
ration that the placement is at a representative
point for the area that is going to be adjusted. The
external sensor is slipped into the conduit befo-
re laying the floor and is connected to the room
thermostat as instructed above.
Floor heating in secondary spaced boarding
Place a conduit right between two heat distribu-
tion plates, attach the conduit on the edge of the
secondary spaced boarding using a clip for con-
duits. Take into consideration that the placement
is at a representative point for the area that is
going to be adjusted. The external sensor is slip-
ped into the conduit before laying the floor and
is connected to the room thermostat as instructed
above.
LK EPS 16
Place a conduit along the long sides of the floor
heating installation facing the nearest short end.
Saw an approx. 2 meters long slot in the EPS-
board and place the conduit in the slot. Take
into consideration that the placement is at a re-
presentative point for the area that is going to be
adjusted. The external sensor is slipped into the
conduit before laying the floor and is connected
to the room thermostat as instructed above.
LK Clip Rail 8/LK Clip Rail 12
Place a conduit along the long sides of the floor
heating installation facing the nearest short end.
Place the conduit at the short end between two
heating pipes and end it approx. 2 meters in. Seal
the end of the conduit with tape or similar to pre-
vent concrete from getting into the conduit. The
external sensor is slipped into the conduit befo-
re pouring the concrete and is connected to the
room thermostat as instructed above.
