BMS System. With the renovation of the building in 2008, a first system for the automation of the systems had already been installed. This was branded "Trend Controls" and provided for a controller in each electrical panel, connected to its probes and relays, with the possibility of communication between the various control units located in the building on a LAN network using proprietary protocol. In order to allow communication between them (in addition to providing internet access to the tenants), a data network was implemented in the condominium, with firewall and central switch in the boiler room and XxX switch for each dwelling. Recently, TECNOZENITH carried out a revamping of the entire BMS system present. A completely new system, branded Swiss Control System, was installed to replace the existing controllers. This new system features significant improvements in performance and thermal system utilization. The new SCS EXD10 controllers feature a native BACnet interface, the open communication protocol developed by the American ASHRAE, which is becoming the most widely used standard in the building management system. However, they are freely programmable, i.e. it is possible to overwrite the regulation strategy at any time, even remotely, from the TECNOZENITH server in Saluzzo, where it is also possible to view and modify the parameters via the internet connection of the Verzuolo building; it is also possible to expand the system by adding the EXD100 expansions (already present in the boiler room), which increases the number of possible controllable points. SCS controllers can interface many protocols used in HVAC systems, such as the KNX, Modbus RTU, BACnet MS-TP or M-bus protocol. Currently, all the controllers installed communicate via Modbus with MID certified electrical meters, to know the consumption of the apartments and the heating system, as well as using the same protocol for interfacing the touch-screen sensor.
