Our BACnet enabled NV1204 Natural Ventilation Controller provides 3 zones of 24VDC control and can operate as a standalone controller or integrated into a BMS with the built-in BACnet communications over MS/TP.
The Natural Ventilation Controller outputs are 24V DC reverse action relays providing proportional positioning control of actuators. An option for a remote manual selection of the ventilation positions is also available.
Each output is individually fused with PCB mounted resettable fuses and the 3 outputs are fed from the high current 24V DC controller supply. Each of the 3 zones can operate independently for individual control of settings based on the corresponding temperature and CO2 levels.
Signals for zone occupancy, external temperature, wind, rain, heat and fire can come from a central BMS over the BACnet communications or from a Master NV1204 controller and these signals will determine the operational status of the controller.
The BACnet ventilation controller is fully compatible with all our CO2 & temperature sensors, outside temperature sensors and the ACO window positioning unit.
We recommend you speak to our team before purchasing the item to check it suits your application and settings.
