Functional Description - Fronius Ohmpilot Bedienungsanleitung

Functional The Fronius Smart Meter records the current power at the feed-in point and transfers the
Description data to the Datamanager. By controlling the Ohmpilot, the Datamanager adjusts any sur-
plus energy that is available to zero. In detail, this takes place by continuously adjusting
the heating element connected to the Ohmpilot.
This means that the surplus energy is used up by the heating element in a continuously
variable manner.
If no temperature sensor is fitted, an external source (e.g. gas-fired heating) must be
used to ensure the minimum temperature is met.
As an alternative, the Ohmpilot can also ensure the minimum temperature. For this, a
temperature sensor must be connected so that the Ohmpilot can measure the tempera-
ture. This may result in electricity being sourced from the grid.
The maximum temperature must be set on the heating element thermostat.
If the heating element does not have a thermostat, the Ohmpilot can also carry out this
task as an alternative (see "Optional Settings" section).
