Desigo room automation has various room operating modes available to efficiently control shading. The system can efficiently control the room depending on the selected room operating mode. This generally occurs during periods of absence, at night, during holidays, when spaces are not occupied.

Optimum room shading must satisfy both energy and comfort-related demands. The following factors are considered:

  • Presence in the room
  • Brightness value (glare, use of daylight).
  • Global radiation (energy entry in room).
  • Solar radiation angle on facade (basis for optimum slat angle and/or blind height).
  • Heating and cooling demand of room.

See description Central Functions.

Room operating modes

Four different room operating modes are available that can control, via central functions, management platform, schedulers, presence buttons in the room or other BACnet participants in the system.

Comfort: The operating mode Comfort refers to a room currently in use (occupied).

Pre-Comfort: The Pre-Comfort operating mode places control for an unoccupied room in a state that can be quickly reset to the desired setpoints for an occupied room.

Economy: The Economy operating mode controls rooms that remain unoccupied for an extended period, for example, at night or over the weekend.

Protection: The building is unoccupied over longer periods in this operating mode (e.g. no renters, factory holidays).

Shading automation

Shading automation includes the functions anti-glare protection, solar position tracking of slats, annual shading, and energy efficiency functions. Curtains are commanded to height and angle via shading automatic functions. All automatic functions are controlled with Desigo room automation by central functions.

See description Central Functions.

Manual, local operation always overrides automatic. The local, manual commands can also be reset, and automatic functions reactivated. It can occur using a time-controlled reset command from the central functions. A presence detector can also reset blinds to automatic after exiting the room.
