Power limit (
PLi
) 1/2
This thermostat complies with EN 50559 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
The heating can be limited by a set number of minutes
per hour The thermostat will then divide the given number
of minutes per hour into 3 periods, depending on the
thermostat’s actual PWM cycle
Note that this function is not applicable to other heating
applications such as wall and/or ceiling heating if it can be
foreseen that unintentional covering up of floor area might
occur. In this case it would be important to assess the
correct period of time for which the floor heating must be
time-limited.
Example:
If obstacles could be present that cover up the floor,
then the heating might need to be limited by a number of
minutes so as to avoid hotspots on the floor
If you want the thermostat to provide heat a maximum of
90% of the time, then the thermostat should be limited by
10% Ten percent of one hour is 6 minutes
