INFORMATION
▪
The DIP switch is used to configure the system. For more information, see
"10.4 Configuration – LAN
▪
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.
Integrating the LAN adapter into the heat pump system allows for the following
applications:
▪ App control (only)
▪ Smart Grid application (only)
▪ App control + Smart Grid application
