heating
If the temperature at store sensor S1 falls below the value [Max. temp. - Hystere-
sis], the electric heating is enabled. If the store temperature reaches the adjusted
maximum temperature, the store will no longer be loaded in order to avoid damage
caused by overheating.
The Reserve is an adjustable excess power which is fed into the grid and not used
for heating. The reserve can be used, e.g. in large PV systems, in order to start the
heating at a later point in time. This reduces power peaks at noon.

10V IN
With the 10V IN variant, the power control takes place via an external 0-10 V
signal. The signal is issued at the terminals 17 and 19.
The parameters Volt 0kW and Volt 3kW can be used for adjusting the power
control curve.
Note
Since there is no communication with the sensor module in this variant, no
excess is measured and balanced.
