Centralized ventilation and heating control with remote access.
The project included the design, the control cabinet planning, the control cabinet construction, the programming of the PLC and the visualization. 4 ventilation systems with rotary heat exchangers, 11 heating circuits, 2 boilers and a cogeneration unit are controlled.
The temperature sensors are queried decentrally via an ASi bus.
External access is secured via a VPN service and incoming fault messages are sent as SMS and e-mail.
