Overview

• The municipal building department identified 64 defective thermostats and radiator valves in about 30 classrooms that could not be turned off.
• The malfunction was first reported two weeks ago after staff logged unusually high indoor temperatures with the city’s facility managers.
• Replacement of the faulty parts has now been commissioned and is expected to take place imminently.
• The affected radiators are standardized authorities’ models with preset settings that prevent manual adjustments and delayed emergency fixes.
• Hölderlin-Gymnasium principal Siegfried Feldmar criticized the absurdity of overheating during hitzefrei closures and urged a rapid resolution to restore normal teaching conditions.
