f Switch the menu function on using the plus button f
or off using the minus button and confirm with the

If you switch off all energy saving modes, ECO Comfort is switched
on automatically.
4.4.4 Commercial mode
The heating contractor can adjust the appliance for commercial
applications, e.g. in doctors' practices or butchers (see chapter
"Installation/settings"). The set temperature is then adjusted
manually. The energy saving mode button is not enabled in com-
mercial mode.
4.4.5 Adjusted use of off-peak tariff periods
(reverse control with dual circuit operation)
This function is not enabled in the factory settings. The heating
contractor can enable reverse control of the appliance.
This means that the appliance evaluates the cheap rate periods of
your power supply utility for 7 days to make the most of off-peak
times. The aim is to start heat-up at the right time so that the
full water heater content heated to the set temperature is only
available to you at the end of the off-peak time (optimum standby
energy consumption).
4.4.6 Setting the temperature limit
Note
If you switch on the temperature limit in ECO Plus or
ECO Dynamic energy saving mode, the appliance switches
automatically to the ECO Comfort energy saving mode.
You can limit the set temperature to between 40 and 60 °C or
switch off the temperature limit.
