Smart Grid Settings - Daikin Altherma 3 GEO Series Installer's Reference Manual

9 LAN adapter
The system can buffer energy in the following ways:
▪ Heat up the domestic hot water tank
▪ Heat up the room
▪ Cool down the room
The Smart Grid application is controlled by the solar inverter/energy
management system, that monitors the grid, and sends commands
to the LAN adapter. The adapter is connected to the solar inverter/
energy management system (digital outputs) by way of connector
X1A (digital inputs).

Digital output 2
The solar inverter/energy management system controls the state of
the digital inputs of the LAN adapter. Depending on the state of the
inputs (open or closed), the Daikin Altherma system can run in the
following Smart Grid operation modes:
Smart Grid operation mode
Normal operation/Free running
NO Smart Grid application
Recommended ON
Energy buffering in the domestic
hot water tank and/or the room,
WITH power limitation.
Forced OFF
Deactivation of unit and electrical
heater operation in case of high
energy tariffs.
Forced ON
Energy buffering in the domestic
hot water tank and/or the room,
WITHOUT power limitation.
INFORMATION
For the system to run in all 4 possible Smart Grid operation
modes, the solar inverter/energy management system
needs to have 2 digital outputs available. If only 1 output is
available, then you can only connect to SG0, and the
system can only run in the "Normal operation/Free
running" and "Recommended ON" operation modes. For
the system to run in "Forced OFF" and "Forced ON", a
connection to SG1 is required (for those operation modes,
SG1 needs to get "closed").
INFORMATION
In case the system layout includes a controllable wall
socket, and the solar inverter/energy management system
activates this socket, SG0 gets "closed" and the system
runs in the "Recommended ON" operation mode. If the
solar inverter/energy management system deactivates the
socket, SG0 (and SG1) get "opened" and the system runs
in the "Normal operation/Free running" operation mode
(due to the 230 V C detection voltage to X1A/L+N getting
cut off).

Energy buffering
Depending on Smart Grid settings (configuration web interface),
energy buffering either happens in the domestic hot water tank only,
or in the domestic hot water tank and in the room. You can choose
whether or not to have the electrical heaters assist with the buffering
of energy in the domestic hot water tank.
