Boiler ECO mode

As long as the boiler is switched on, the temperature
of the water is automatically held constant. Boiling
water is therefore available at any time of the day.
There are, however, times when you don't need
boiling water, for example, when you are asleep. In
order to prevent the temperature of the boiler being
unnecessarily held constant, you can use the energy-
saving ECO function.
Whenever the ECO function is activated, the 6-hour
night period starts immediately. The boiler water is
not heated during the night period. The starting time
of this period applies every day as long as the ECO
function is activated
1 The ECO starting time is not automatically changed at
the start of summer and winter time. You then have to set
the starting time again.
2 The ECO function is deactivated if the boiler is switched
off by means of a CombiSwitch or in the event of a power
failure.
Activating ECO:
The ECO function can only be activated when the
appliance is ON.
