LOAD MONITOR
Integrated load monitor
F470 is equipped with a simple form of integrated load
monitor, which limits the power steps for the electric
additional heat by calculating whether future power
steps can be connected to the relevant phase without
exceeding the specified main fuse. If the current would
exceed the specified main fuse, the power step is not
permitted. The size of the property's main fuse is spe-
cified in menu 5.1.12.
