IMPORTANT! Plug & Play - no further settings are required for this application after suc-
cessful connection to the inverter.
The Fronius Smart Meter records the current power at the feed-in point and transfers the
data to the inverter. By controlling the Ohmpilot, the inverter adjusts any surplus 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 consumed in
a continuously variable manner with the heating element.
Depending on the surplus power, the individual phases are switched on or off and the
remaining power is consumed at L1. As a result, the heating element output is divided by
three.
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 ensure the minimum temperature. To do this, a tem-
perature sensor must be connected so that the Ohmpilot can measure the temperature.
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 chapter
IMPORTANT! A heating element with implemented neutral conductor is required.
