Issue
The Analogue Input (AI) Objects were functioning correctly but suddenly failed. Instead of displaying the expected default value of 20.0, they now show their last recorded value. Upon testing, the inputs return different values, and temperature detectors consistently read 150°C, while heat flow rates show 0 m³/hr.
