Zone Grouping within ClimaVision

A zone represents a single thermal space or logical control group within the system. Typically, a zone corresponds to a relatively small physical space (such as an office, meeting room, or retail section) where a single temperature setpoint and schedule are configured and managed by the user.

In some scenarios, however, the space may be large or served by multiple pieces of equipment. This is common for smaller equipment like Fan Coil Units (FCUs). In such cases, multiple edge controllers (modules) may be deployed within the same zone to control different pieces of equipment serving that space.

Some sample spaces that this configuration is useful :

• Open offices

• Auditoriums

• Retail floors

• Gymnasiums

• Warehouses

• Airport halls

In these cases, each edge controller still manages one piece of equipment for conditioning the space, while all of these controllers operate under the coordination of the CCU enforcing each of the controllers work together in a systematic way so as not to waste energy by the equipment fighting against each other. 

The following control parameters will be shared among all the controllers that are assigned to the same zone: 

• Temperature setpoints (including any setpoint adjustments)
• Conditioning mode (heating, cooling, auto, off)
• Fan mode for standalone equipment
• Schedules
• Occupancy states

Impact of Zone Grouping (a.k.a. Multi-Module) across portals, apps and CCU

Zone Grouping (Multi-Module) is a configuration in which more than one device is paired within a zone. The ClimaVision system supports up to 3 modules per zone currently.  These may be paired as a device profile (e.g., VVT-C Zone), a system influencing profile (e.g., OTN), or a standalone profile (e.g., Hyperstats, MyStat). 

NOTE: Multiple profiles may be used within one zone.

In CCU multiple modules can be added as shown below.

A maximum of 3 modules per zone can be added.

In Zone Grouping (Multi-Module) zones, all of the modules will have the same schedule state, which is indicated on the zone screen on the CCU and in ClimaVision.

In Portals

Any external schedule influence once triggered will be influencing the entire zone, irrespective of whether the other modules are enabled via configuration for that state.

Once the schedule state is consumed by the zone from the module of the highest rank in the multimodule, then the desired temperatures are inherited by other modules in the multimodule zone.

The table below is about various possible combinations of schedule states that a multi-module zone in the building can experience at any given point of time, along with the zone status and Desired temperatures.

Note: A CCU operates according to a time zone that is set during the CCU registration process. If there are any changes to the time zone, the set schedule will be altered according to the time zone set. Therefore, it is recommended to restart the application whenever the time zone is modified to ensure the schedule remains accurate and the system functions correctly.
