This thermostat complies with EN 50559:2013 (VDE 0705-559) for electrical floor
heating . The regulation applies to electrical floor heating, with a maximum floor
weight of 4 kN/m² . To ensure that hotspots due to unintentionally covering up the
surface are avoided, the heating function can be time-limited as per EN/DIN .
Note that this function is not applicable to other heating applications such as wall
and/or ceiling heating
If it can be foreseen in advance that unintentional covering up of a floor might occur,
then it is important to assess the correct period of time for which the floor heating
must be time-limited .
The heating can be limited by using a set number of minutes per hour .
The factory setting is 0 minutes .
