Ventilation and heating control

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.
