To Be Considered When Designing The System - Fronius Ohmpilot Instructions De Service

Other resistive loads such as infrared heaters, towel dryers, etc. can also be controlled.

when designing
Ohm pilot phase control
the system
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 Datamanager, the Ohmpilot can be used together with the dyna-
mic 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 in-
verter, etc.) can also be used. However, since information about the power produced and
the consumption is missing, this cannot be displayed in Solarweb.
NOTE!
Due to high heat outputs, the Ohmpilot cannot be operated in emergency power
situations.
It is therefore recommended to install the Ohmpilot outside of the backup power branch.
If the Ohmpilot is installed in the emergency power branch, the existing automatic circuit
breaker of the Ohmpilot must be switched off in the event of a power failure. Alterna-
tively, the heating element measurement must be changed to manual and the minimum
temperature and legionella prevention must be deactivated. (See chapter

when emergency power mode starts, these settings cannot be changed during a power
failure.
