| Introduction
The ability to define and view ClimaVision profiles in Hayloft and use them in CCU is a smarter way of streamlining system profiles under a common platform. This integration ensures automatic subscription to all changes made in Hayloft, with tags and points created directly in Hayloft. Consequently, CCU no longer needs to create tags or points when a new profile is paired.
Moreover, the editing and updating ClimaVision profiles in Hayloft, with the updated model available in CCU, ensures that existing models in CCU are synchronized with changes made in Hayloft, eliminating the need for code-level adjustments in CCU whenever there are modifications in points or changes in tags or enums.
There are about 28 system and zone profiles used for controlling HVAC equipment. These profiles, consisting of read and write points, are created independently in each CCU during pairing. There are several constraints which are addressed with this feature:
- Standardization: Points and tags created by CCU lack consistency across profiles and developers, failing to conform to Haystack standards.
- Normalization: Tags in different profiles often have varying meanings, complicating comprehension and usage.
- Development Cycle Time: The absence of standardization increases development time for creating profiles or tags.
- CCU Performance: Tags are extensively used in CCU to display data, impacting performance. A significant improvement of 60-70% in query performance is expected when CCUs fully migrate to fetch models from Hayloft.

VAV Staged RTU | System | vavStagedRTU | No |
VAV External AHU Controller | System | vavExternalAHUController | No |
- Searching with the domain model name, would display the VAV system profiles
The description of the model's name and the model level tags can be observed under the ClimaVision models.
- Click on a VAV model
The associated points and tags related to the model is displayed.
