Appendix HVAC Room Control 9 9 Appendix 9.1 HVAC Room Control HVAC plants and their devices in the room influence the room conditions in closed rooms. A pleasant room climate is achieved during occupancy by controlling temperature, humidity, and air quality. HVAC plants in the room are divided up into plant families that differ in principle in design and how they act.
9 Appendix HVAC Room Control 9.1.1 BACnet Priorities for HVAC Applications The following table illustrates the priorities used in Desigo. Priorities in HVAC Priority Description Example 1 Emergency mode 1 ‒ 2 Emergency mode 2 Life safety (fan cannot be switched due to smoke) 3 Emergency mode 3 ‒ 4 Protection mode 1 ‒ 5 Protection mode 2 Locking via a dependent object (for example, the damper must be opened before the fan can be switched on).
Appendix Lighting Control 9.2 9 Lighting Control Control requires a variety of information about external influences and user actions to be able to cover requirements. The following illustration provides an overview of influences considered as part of lighting control.
9 Appendix Lighting Control Gray: Entire building Green/yellow: Rooms for a renter, for example, one floor. Orange: Local manual operation The control concept is oriented on the following principles: Distribute into independent functions that determine a lighting command. Prioritization of individual functions. Evaluation of all functions and decides, based on the priorities, which state the lighting assumes. 9.2.
Appendix 9 Lighting Control 9.2.1.1 Local Operation BACnet priority Room state An object is switched at priority 13 with the room operator unit. So that light switches, presence detectors, scheduler, or Management System (priority 13) are equal at switching. In other words, the last condition always applies. 8 13 13 8 13 13 7:00 17:00 18:00 Action 13 Off On Off 13 On Off On Off On Off On Off Local Operation for Lighting 9.2.1.
9 Appendix Lighting Control 9.2.1.3 Central Function The central function can override or switch multiple rooms in a building with the same priority. Central functions are classified by building requirements: Renter Sections Occupancy function (office/production) Floors Entire building Central functions use the same BACnet priorities as local control. So that override at priority 8 is permanent and only temporary at priority 13.
Appendix 9 Lighting Control 9.2.1.5 Remote Operation and Emergency 2 8 13 13 Action BACnet priority Room state All pending commands are overridden on emergency lighting until the state is reset.
Appendix Lighting Control 2 8 13 13 Action BACnet priority Room state 9 2 8 13 13 7:00 13 Off On On Off Off Emergency Lighting through Operation on the Management System 9.2.2 BACnet Priorities for Lighting The following table illustrates the priorities used in Desigo. Priorities in Lighting Priority Description Example 1 Emergency mode 1 ‒ 2 Emergency mode 2 Lighting can be switched on during a fire alarm to light escape routes or in support of first responders.
Appendix Shading Control 9.3 9 Shading Control Control requires a variety of information on environmental influences and user interventions to meet requirements. The following figure provides an overview of influences considered as part of blinds control. Positioning of blinds in the building, how the rooms are used, and assignment of rooms to organizational units determine what information acts on blinds control: Wind speed monitoring acts on all blinds in the building or portions thereof.
