EXAMPLES OF LAYING ADPSV CABLE
c) Regulation
For economical operation it is necessary to install a thermostatic regulator, which is currently available
at FENIX – for example, the EBERLE EM 524 87 + moisture probe ESD 524003 + thermal sensor
TFD 524004. Or you should install a differential regulator that is suitable for smaller-sized applications
and roofs that are well insulated externally: EBERLE DTR-E 3102, EB-Therm 800. It is recommended
to set the temperature to -5°C to +3°C.
3. Use in accumulating and semi-accumulating floor heating
a) Dimensioning

If the floor heating is to be used to heat a room, it is necessary to know the thermal loss value for the
building in order to select the most suitable heating system. The installed output for the accumulating
heating system should correspond to a multiple of 3 times the calculated thermal loss of the building
and increased by 10% to 30%. For a semi-accumulating system, the installed output should
correspond to a multiple of 1.1 to 1.3 times the calculated thermal loss. If the full amount of the output
calculated in this way cannot be installed in the floor, due to the maximum recommended outputs, an
additional heating device must be used.

Recommended flat output for accumulating heating is between 200 and 300 W/m 2
. Maximum is
400 W/m
2
.

For semi-accumulating heating, we recommend using flat outputs of 150–250 W/m 2 .
b) INSTALLATION
Installing into concrete

Please read first the General Terms and Conditions.

The perimeter of the area must be separated from the vertical structures by an expansion joint.

In case that cables are laid in an area larger than 20 m 2
or with a diagonal greater than 7 m, it is
necessary to account for expansion of the foundation materials. The heating cable must not cross the
expansion joints. The non-heating connecting cables located at the expansion joints must be laid
loosely in a protective tube. All installed elements – cold connection end, thermostat’s probe – where
they pass from the wall to the floor must be placed in installation tubes and must allow for movement
of the floor and wall relative to one another.
