4.4.3 Selecting energy saving mode
eco comfort (factory setting)
This energy saving mode always offers you the maximum amount of hot water and therefore maximum
comfort.
In ECO Comfort energy saving mode, the set temperature is automatically reduced after a week from
85 °C to 60 °C.
In ECO Comfort energy saving mode, you can also adjust the set temperature manually at any time between
61 °C and 70 °C. This is also possible immediately after commissioning and after automatic reduction of
the set temperature. If you select a set temperature higher than 70 °C, the set temperature is automatically
reduced again after a week to 60 °C.
eco plus (with single circuit operation)
This energy saving mode offers you the advantage of energy savings, as heating is only carried out after
considerable draw-off.
In ECO Plus mode, the appliance heats up automatically to the set temperature of 60 °C once you have
drawn off 40% of the water heater content.
eco dynamic (with single circuit operation)
This energy saving mode offers you maximum energy efficiency through intelligent dynamic matching to
your draw-off behaviour.
When you select ECO Dynamic mode, the appliance evaluates your draw-off times and quantities for a
week. The next week, you have the required mixed water volume available at the draw-off time. The ap-
pliance monitors your user behaviour and automatically adjusts the heat-up times as required.
This energy saving mode is optimal if you require hot water at the same time during a week. If your draw-
off times change, hot water is available the next week at the new times.
The set temperature is set immediately to 60 °C.
note
in commercial mode (see chapter "commercial mode") and in manual operating mode
(see chapter "appliance description"), the eco menu functions are skipped.
