Retrofit Market Hall Burgdorf

The market hall, which was opened in 1932 and is now a listed building, was extensively renovated and technically modernised in 2015. The building
has a surrounding gallery, a multifunctional event hall with modular partition walls and separate entrance and toilet areas. The capacity is 1,200 seated or 3,000 standing guests. Our aim was to modernise the building automation system within just five days without significantly disrupting operations. The outdated system from GTS Automation GmbH, which had to be replaced due to the company's closure in Switzerland and its takeover in Austria, was modernised with a new CX5120 control unit that separates logic from PC operation. In the "FOPPA" panel, we extended the existing PLC unit with a BK9100 IO coupler to improve the signalling. The KNX connection is now made directly via the PLC. Commissioning began with the transfer of current parameters and fine adjustments based on operational findings. A new optimisation was carried out after 2 months. The biggest challenge was not to interrupt operations and to implement the modernisation quickly.
