After a Sunny WebBox
is replaced,
Sunny Portal contains
two plants with the
same name.
A Sunny WebBox that is
supplied as a replacement
device logs into Sunny Portal
with a new plant identifier.
Sunny Portal creates a new plant
for this plant identifier, even if
you gave the plant the same
name.
Assign the plant identifier of the old
system to the replacement device
(see section 9.2.3 ”Adjusting the Plant
Identifier for Sunny Portal” (page 52)).
In the replacement device, enter the
e-mail address of a user who has Sunny
Portal administrator rights to the plant.
In Sunny Portal, delete the new plant the
replacement device created.
