3.1.10 Trace boiler
The trace boiler setting is included to ensure that the heating cable temper-
ature does not exceed the boiler temperature. The boiler temperature is
measured with the external temperature sensor. The HWAT-ECO memo-
rizes 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
selected temperature difference from 5°C to max 15°C between boiler tem-
perature 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 trace
boiler LED will be on.
