Central functions basics

What are central functions?

Central control functions permit and support the centralized control and coordination of defined groups. Typical centralized control functions include:

• Central occupancy definition
• Central setpoints.
• Central hot water/chilled water coordination (Optimization of primary plants, supply chain optimization).
• Central lighting control.
• Central emergency lighting control
• Central blinds control.

Various source provide input for a central control function, including:

• Signals from an external system.
• Commands from a system operator.
• Commands from a building user.
• Signal from Desigo automation stations
• Commands from a scheduler program.
• Commands from superposed central control.

These signals and commands are evaluated by the central control function. The central control function sends the result via the group manager and group members to the subordinate control functions.
