Explanation
0 DHW mode is OFF (only heating mode)
ECO Economy mode. The DHW will only be reheated to
140 °F (60 °C), if the temperature has signifcantly
fallen. This reduces the number of burner starts and
saves energy. As a result the water may be a bit
colder initially.
86 – 140
The temperature set on the BC10 is a temperature
that cannot be changed using a RC thermostat.
Aut The temperature is set on the thermostat (e. g. RC35).
If no thermostat is connected, the maximum DHW
temperature is 140 °F (60 °C).
