Connectivity - Energy state
The sub menu 'Energy state' can be used to influence the heat pumps's operation based on
availability of renewable energy - for instance from PV-panels.
There are two options to make use of this logic:
- Use Modbus: LG Energy Storage System (ESS) or another third-party device is connected by
Modbus serial line.
- Use Digital inputs: A third-party controller (e.g. SmartHome controller or PV inverter) is
connected through 230 V inputs ("SG-Ready contacts").
Using Modbus RTU allows to use eight different energy states, while Digital inputs provides four
different energy states.
NOTE
Use setting ‘Digital inputs assignment’ to replace Energy state 3 and/or 4 with any of Energy
states 3~8.
