The storage temperature set point and the timing are field settings.
Refer to "5.12. Field settings" on page 18
how to set one or more field settings.
■
[1-00] Status: defines whether the domestic water heating
(storage mode) during night is enabled (1) or not (0).
■
[1-01] Start time: time of the night at which the domestic water
should be heated.
■
[1-02] Status: defines whether the domestic water heating
(storage mode) during daytime is enabled (1) or not (0).
■
[1-03] Start time: time of the day at which the domestic water
should be heated.
INFORMATION
Be aware that despite the automatic storage is a
pre-programmed schedule timer, it is only active when the
schedule timer is enabled. This means that you have to
push the rp button and confirm that the p is displayed to
make sure that the automatic storage will operate.
■
[b-03] set point: storage temperature (see figure
water heating modes" on page
■
[b-02] Status: defines whether the weather dependent domestic
water heating is turned ON (1) or OFF (0).
If enabled, the storage set point will be set weather dependent.
In case of a higher ambient temperature (e.g. during summer-
time), temperature of supply water to the domestic hot water
tank will be higher too, so that storage temperature set point can
be set lower in order to keep the overall equivalent hot water
amount the same during the whole year. Therefore it is
recommended to use this function.

■
The ambient temperatures for weather dependent
domestic water heating (see figure) are fixed and can
not be changed.
■
If weather dependent domestic water heating is
enabled [b-02], the storage temperature will be set
automatically and the field setting [b-03] will be of no
importance.
INFORMATION
■
Make sure the domestic hot water is only heated up to
the domestic hot water temperature you require.
Start with a low domestic hot water storage
temperature set point, and only increase if you feel
that the domestic hot water supply temperature is not
sufficient for your needs (this depends on your water
using pattern).
■
Make sure the domestic hot water is not heated
unnecessary. Start with activating automatic storage
during night (default setting). If it seems that the
domestic hot water night storage operation is not
sufficient for your needs, an additional storage during
daytime can be set.
■
For energy-saving purposes, it is advised to enable
the weather dependent domestic water heating.
