Installation Manual
Cause and corrective measure
The serial number and/or the registration ID may have
been entered incorrectly.
Corrective measures:
• Ensure that the entries are correct.
It is possible that the registration procedure was previously
initiated but not completed.
Corrective measures:
• Perform a complete reset of the
Sunny Home Manager (see Section 10.6,
page 75).
It is possible that the Sunny Home Manager is not cor-
rectly connected to the router.
Corrective measures:
• Ensure that the Sunny Home Manager is correctly
connected to the router (see Section 7.4, page 47).
DHCP is possibly not activated on your router or there is a
proxy server in your network. For this reason,
Sunny Home Manager cannot establish a connection to
Sunny Portal.
Corrective measures:
• Establish the connection to Sunny Portal using the
Sunny Home Manager Assistant (see Section 10.4,
page 73).
