● Cross-technical installation coordination to ensure smooth functional
interplay of the various installations
● Centralized, room-wide access point to operate and monitor a room
The application functions of the individual technical installations contain
functionality required for technical installation-specific control. Additional
functionality assuming coordination with other technical installations is part of
room coordination. As a result, project-specific Desigo room automation
requests and changes can be carried out without changes to technical
installation-specific application functions.
Examples for coordination functions are coordination of HVAC and shading
functions and coordination of shading and lighting functions.
Room coordination offers a centralized, room-wide access point to operate and
monitor a room. This allows users to enter common data for several technical
installations only once and retrieve them as a group.
Examples:
● Predefinition of the room operating mode (across all technical installations)
● Predefinition of a scene for the entire room
● Queries for general occupancy
● Common alarm for system alarms
The room coordination default solution influences the following functions:
Various sources influence and determine the room operating mode:
● Centralized commands from scheduler programs or manual intervention
● Local commands from presence detectors or scheduler program override
Room coordination offers a centralized, room-wide access point to operate and
monitor a room operating mode. The individual technical installations
separately acquire all relevant information.
Scenes are defined to command several or all technical installations in a room
via one single command, e.g., brightness of a lighting zone, or blinds positions
in each shading zone can be defined for each scene. Room coordination:
● Controls a scene as per the predefined values
● Changes the predefined values
Both are carried out by the room user.
Room coordination supports room temperature control via blinds control. The
various HVAC data is analyzed to determine the thermal room load and the
associated signal definition for blinds control:
● Load if energy must be supplied to the room via the blinds position
● Unload if no additional energy must be supplied to the room via the blinds
position
Blinds control determines the optimal blinds position in dependence of room
occupancy and solar position (thermal radiation and glare).
Manual room user manipulations (e.g., manual lighting and shading commands,
or manual changes to the room temperature setpoint) can result in inefficient
energy operation. Each zone and each technical installation is checked for
inefficient definitions to be pointed out to the room user. Room coordination
then summarizes the results and visualizes them on the room operator unit. The
room user can then reset all manual entries (which lead to inefficient plant
operation) by one single pressure of a button.
One common alarm is set up for each room to keep down the number of set up
system alarms. To this end, room coordination acquires status information
(normal/alarm) for each zone and each technical installation, and determines
the room-wide alarm state as a common alarm.
