3.1.10 Trace boiler
The trace boiler setting is included to ensure that the heating cable
temperature does not exceed the boiler temperature. The boiler
temperature is measured with the external temperature sensor.
The HWAT-ECO memorizes the highest measured temperature over
the last 24 hours. With the up/down arrow keys the setting can be
altered between OFF and ON with a temperature difference from 5°C
between boiler temperature and maintain temperature. Press Enter to
confirm your choice. If the boiler temperature is too low the maximum
temperature is lowered to the boiler temperature minus the trace
temperature. In this case the green trace boiler LED will be on.

With this setting you can switch the sound into different modes:
continuous, 10 minutes, 1 minute, 10 seconds or off.
