Passivent has introduced the iC9000 – a new and improved control system for use with its natural and hybrid ventilation systems. It offers all the benefits of the existing iC8000 controller in terms of energy and operational efficiency, multi-zone control and occupant comfort, but with added features and benefits that make it a more sustainable solution.
Using Passivent’s own natural ventilation software, it can be used as a stand-alone system or integrated with a Building Management System via BACnet communication.
The iC9000 includes the new ‘Rotary’ sensor, a networkable, feature-rich user interface which combines the room sensor and room override into one unit. Its rotating dial, menu options and push-to-select functions via a full LCD display with configurable readouts, make the user experience more intuitive. It also features a colour‑coded halo LED ring, with green, yellow and red signalling changing CO₂ levels in the building.
The system monitors air quality in real time, reducing the burden on building services by using CO₂ and temperature-based demand control to regulate airflow within the required zones. It includes options for remote monitoring and data logging and, with less field wiring required compared to the iC8000 system, it can also offer a reduction in the overall cable and labour costs for a project.
