3.1.10 Trace boiler

The trace boiler setting is included to ensure that the heating cable tem-
perature 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 tempera-
ture difference from 5°C between boiler temperature and maintain tempera-
ture. 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.
