Load control

The Load control is a functionality of the Energy Actuator, where the Energy Actuator is parameterized as
a master that can control up to ten further Energy Actuators as slaves. The master receives Power values
from the slaves that are added internally to the Send sum power values. If the Send sum power values
exceeds a parameterized load limit, the master sends Load shedding stages on the bus.
A separate Load shedding stage can be parameterized with every slave for each output. The slave re-
ceives the Shedding stage and switches all outputs off with the respective shedding stage. The master in-
creases the Shedding stage until the Send sum power values falls below the allowed load limit.
The Power values, which the master receives, can be the respective Active power total of another Energy
Actuator, the Active power of an individual output or the Power values of the master. Furthermore, the re-
ceived power values can be the power values of another KNX device, e.g. the Meter Interface Module
ZS/S.
