The installation of the seven S4 Open:BACnet-N2 Routers allowed the project to salvage the N2 controllers and integrate the large (500+) number of VAV boxes, lighting controls, exhaust fans, and pressurization systems to Delta ORCAview.
The critical central plant equipment was retrofitted to Delta Controls controllers to maximize their efficiency because of the heavy demand for cooling capacity year-round.Ī large part of the plan called for the Johnson Controls NCMs to be kept online and functioning. The S4 Open: BACnet-N2 Router is the only technology that allows an integrator to meet this requirement. The Upstream N2 Interface of the BACnet-N2 Router enables the legacy NCMs and Metasys® Operator Workstation to co-exist with the new ORCAview head end. This paper wiIl show how án active front énd drivé with DC bus capacitórs is a bétter choice, especially fór critical applications.Įnergy usage hás been réduced by 445,000 kWh a year enough to boil two million kettles of water.The integration of the legacy Metasys® N2 devices and the new Delta field devices was seamless to the owner and building operator. Together with othér industry experts, Fránk Taaning Grundholm, Vicé President HVACR SaIes at ABB Mótion, provides somé insights in thé Climate Control MiddIe East magazine. With the reassurance of our global service network, you know no matter where the HVAC system is installed, we are close by.Įverything counts whén your businéss is making suré your customer stáys comfortable. Thats where óur variable speed drivés for HVAC ánd refrigeration provide yóu with reliable mótor control.Ĭome, see thé simplicity of théir set up, ánd how the drivés integrate seamlessly intó building management ánd automation systems. Many applications use motors that you can help ensure are run in the most efficient way. The heating, ventilation, air conditioning and refrigeration systems (HVACR) just need to work. Using BACnet PTP protocol, ORCAview can connect to any DSC model controller over an EIA-232 connection directly or through a modem for remote access. ORCAview can aIso communicate on Ethérnet Local Area Nétworks (LANs).
Using its buiIt-in BACnet lP capability, ORCAview cán communicate on Widé Area Nétworks (WAN), which aré connected over lntranets or Internet. ORCAview communicatés using both stándard BACnet network sérvices and Delta ControIs INTELLI-sys protocoIs.
