  If the Walther Temperature Controller displays '-1999' (blinking!), it indicates that the displayed value is below the measuring range. To resolve this: * Verify that the medium being measured is within the controller's measuring range (not too hot or too cold). * Check the sensor for a break or short circuit. * Inspect the sensor connection and connecting clamps. * Examine the line. * Ensure the connected sensor matches the configured sensor type.
