LED Description Behaviour
LD4 Indication of Smart Grid
activity.
▪ LED ON: system running in
the "Recommended ON",
"Forced ON", or "Forced OFF"
Smart Grid operation mode.
▪ LED OFF: system running in
the "Normal operation"
Smart Grid operation mode,
or operating in normal
operation conditions (space
heating/cooling, production
of domestic hot water).
▪ LED flashing: LAN adapter
performing a Smart Grid
compatibility check.
INFORMATION
▪ The DIP switch is used to configure the system. For more information, see
"9.4Configuration – LAN adapter"[4112].
▪ When the LAN adapter performs a Smart Grid compatibility check, LD4 flashes.
This is NOT erroneous behaviour. After a successful check, LD4 will either stay ON
or go OFF. When it keeps flashing for more than 30 minutes, the compatibility
check failed, and NO Smart Grid operation is possible.
