3.3.1 Power store operation
The integral 15 litre stainless steel
power store
provides
instantaneous delivery of domestic hot water from the
aquaPLUS boiler.
When the
power store
is switched ON the boiler will
automatically light periodically to maintain the internal
temperature of the store. When the
power store
is
switched OFF a short delay may be experienced in
obtaining hot water at the tap.
Note!
The power store is factory set off.
• The
power store
is activated by turning the hot water
temperature control knob (1) all the way to the very
right for a short time. Reset the hot water
temperature control knob to the desired setting. The
symbol "C" (comfort) appears in the display and
shows that the
power store
is activated. The boiler
will now provide instantaneous delivery of hot water
directly when a hot water tap is turned on.
• The
power store
is switched off by momentarily
turning the knob (1) to the left, as far as the stop. The
"C" symbol no longer appears in the display. Reset the
hot water temperature control knob to the desired
setting.
Note!
Irrespective of whether the power store facility
is switched on or off, the boiler will
automatically operate to provide hot water
whenever a hot water tap is opened.

3.3.2 Obtaining hot water
When you open a hot water tap (1) at a draw-off point
(wash basin, shower, bath etc.), the appliance supplies
you with the hot water you require.
When a certain volume of water has been drawn off, the
appliance is brought into operation automatically and
the
power store
is re-filled (in some circumstances, the
appliance may operate only after the water has been
drawn off).
Warning!
The appliance is equipped with an automatic
protection function against legionella. If the
temperature in the power store falls below a set
temperature for more than 23 hours the boiler
will operate automatically to thermally disinfect
the store.
Important note!
After completion of the thermal disinfection
process there is a possible risk of scalding when
drawing off hot water.
Hot water temperatures of up to 65°C are
possible immediately from the tap.
