"ECO" button
By pressing and holding the "ECO" button
lights, you can switch between Comfort mode and Economy
mode.
Comfort mode: button is not lit (factory setting)
The appliance is held constantly at the set temperature. This
means that hot water is available almost instantaneously at the
tap. Consequently the appliance will switch on at intervals, even if
no hot water is being drawn.
ECO mode with demand detection, button is lit
The demand detection function enables maximum gas and water
economy.
Briefly turning a hot water tap on and then off again signals
demand to the appliance which then heats up the water to the set
temperature.
Hot water is thus available in about 1 minute.
ECO mode, button is lit
Water is not heated up until hot water is drawn. This means that
there is a longer waiting period before hot water is available.
