They are all definitions for automatic optimisation of hvac control systems by microprocessor controls to maintain a comfortable environment
They can be integrated with security access, fire alarm, lighting control & facility management systems to further optimise building performance, safety & efficiency
Why DDC?
Precise, accurate, automatic control loops continuously adjust performance based on varying indoor & outdoor conditions with no manual tuning
Provides computing power at a low cost/small size/high performance for ahu, vav, fcu & chillers
Software applications make changes easy to suit expansion or eorganisation
“Standalone” or networked with pc(s) again suits expansion or eorganisation
Self checking diagnostics improve reliabiity
Coordinated capability, with remote communications to other units & site(s) to automatically transmit alarms & collect historical data
