Sheath in conduit approx. 2 meters into the room before embedding in concrete; consider location for the sensor
carefully as it must be representative of the whole floor. The end of the sensor must be placed between two
floor heating pipes. Seal the end of the conduit with tape or similar to prevent concrete entering the conduit
bore. Position the conduit as close to the surface as possible as this provides optimum control of floor surface
temperature. Install the cable sensor prior to pouring concrete. The external sensor is slipped into the conduit
before pouring the concrete. Connection instructions to the room thermostats are given above.

Battery replacement
LK Room Thermostat RF ICS comes with three 1.5 volt LR03 batteries (AAA). The batteries have a life
expectancy of two years. Life expectancy is affected by the user's choices, such as activated background lighting.
The thermostat display has a battery icon that shows the battery status. The battery should be replaced when
the icon only shows one segment.
Battery replacement is performed as follows:
1. Remove the thermostat from the wall by gently pushing the securing plate with a screwdriver while at
the same time pulling the thermostat from the back-plate (the push-lock is positioned on the underside
of the thermostat).
2. Replace the batteries and then click the thermostat into position again. After the battery replacement,
the thermostat automatically returns to normal operation.
