SWE Energie GmbH is planning to set up an intelligent house connection station system (IHAST system) in digitization stage 4. For this purpose, the construction of the communication infrastructure for the heating network must be established; existing house connection stations must be upgraded.

In order to connect the existing stations to the communication infrastructure for the heating network, switch cabinets must be replaced, specifically dismantling controllers, probes, cables and cables and lines and then reassembled. After assembly and upgrading, the prerequisites are met for these stations to be integrated into the communication infrastructure for the heating network

- Conversion of 265 existing control cabinets, each with one or more controllers

- partially re-laying of a total of approx. 10,000 meters of electrical Cables and wires of different cross-sections in small quantities divided into 265 HASTs

- approx. 1,400 meters of cable carrier systems

- Replacement of a total of 262 outside temperature sensors

- Replacement of 1,750 temperature sensors in existing plants
