Priva provides the route to upgrading controls for Marks & Spencer
The capabilities of Priva control equipment to be integrated with other manufacturers’ peripheral equipment is being exploited in the remodelling of Marks & Spencer stores.
As part of Marks & Spencer’s remodelling of its stores, Matrix Control Solutions is upgrading building-management systems in 13 stores using controllers from Priva Building Intelligence. At the Reading store, for example, the ability of Priva equipment to utilise other manufacturers’ peripheral equipment is being exploited — with existing cabling and sensors being retained, leading to a much simpler upgrade solution and savings in capital costs. The Priva controllers at Reading are generally a direct replacement for the older BMS. However, Matrix has also linked the BMS serving the HVAC systems to the existing IT network. The approach has been to use Priva Compri HX8 controllers to manage HVAC services using the XML protocol to provide information that can be transmitted across modern TCP/IP networks. In a new store at Derby, eight Compri HX4 controllers have been installed, together with a Compri HX8 to enable the building-control system to be interfaced with each of the chillers via Modbus. Phil Ingleby, a director of Matrix Control Services, says, ‘IT infrastructures offer ideal communications paths for intelligent controllers, and controls manufacturers such as Priva Building Intelligence, have taken steps to ensure that their products can communicate with a range of protocols over modern networks. As a result, the end user benefits from being able to fully utilise their existing network — ensuring a simpler installation that delivers savings in capital costs and engineer.’
