My Daikin Altherma supports the Daikin LAN adapter option kit but the application keeps indicating that the Daikin LAN adapter is initializing

When Updating the LAN adapter firmware from version 17003901 to 17003902, a mandatory power reset of the Daikin Altherma system is required. This was informed via a pop-up in the Daikin Online Control Heating Application. If you forgot to do the mandatory power reset on your Daikin Altherma system, the application will keep indicating that the Daikin LAN adapter is initializing.

It can take up-to 15 minutes before the Daikin LAN adapter is initialized. If however after 15 minutes the Daikin LAN adapter still indicates initializing in the Daikin Online Control Heating application, please try the following actions:

  • Reboot your Daikin Altherma system by switching the power off and on. 
  • Verify with your installer that your Daikin Altherma user interface is configured to work in “RT control”. At the moment, “LWT control” or “ext RT control” are not supported by the Daikin LAN adapter.
