To Be Considered When Designing The System - Fronius Ohmpilot Bedienungsanleitung

6 - 9 kW
Other resistive loads such as infrared heaters, towel dryers, etc. can also be con-
trolled.
To be considered
NOTE!
when designing
the system Ohmpilot phase control
The Ohmpilot controls to the sum of all phases. The Ohmpilot is not suitable for
the rare case of phase-accurate billing.
NOTE!
Ohmpilot and Fronius Datamanager / Hybridmanager
Only one Ohmpilot can be used per Fronius Datamanager / Hybridmanager.
NOTE!
Ohmpilot and dynamic power reduction
From software version 3.13.1-x and onwards on the Fronius Datamanager or
1.11.1-x onwards on the Fronius Hybridmanager, the Ohmpilot can be used toge-
ther with the dynamic power reduction of 0-100%.
NOTE!
Use of other generation sources
With the Fronius Datamanager Box 2.0, any other generation source (CHP, third-
party inverter, etc.) can also be used. However, since information about the power
produced and the consumption is missing, this cannot be displayed in Fronius
Solar.web.
NOTE!
Due to high heat outputs, the Ohmpilot cannot be operated in backup power si-
tuations.
It is therefore recommended to install the Ohmpilot outside of the backup power
branch. If the Ohmpilot is installed in the backup power branch, the existing au-
tomatic circuit breaker of the Ohmpilot must be switched off in the event of a
power failure. Alternatively, the heating element measurement must be changed
to manual, and the minimum temperature and legionella prevention must be de-
activated. (See chapter
for these functions exceeds the power limits in backup power mode. Since these
functions are blocked when backup power mode starts, these settings cannot be
changed during a power failure.
Danger from connecting an incorrect load (e.g. fan heater).
The result is destruction of the load.
