Service by subcontractor
As depicted in the figure, the user can accomplish two things using the sign-up (registration) process:
- Log in the first time on Climatix IC
- Assign the role of owner to the currently connected controller
The installer can then activate other plants in this way or an alternative way.

Short characteristics
- The service business can be outsourced to a subcontractor who works autonomously.
- The plants are assigned to the subcontractor's area by either pre-registering the plants or via the tenant key (not depicted in the image).
