Operation manual
8
Manual storage
This mode is to be selected manually and will make the indoor unit
immediately deliver hot water to the domestic hot water tank. This
mode will continue until the storage temperature set point is reached.
It is a one-time hot water making feature.
Selecting manual storage operation for domestic water heating
1
Push and hold the
button for 5 seconds to activate manual
storage operation.
The
icon will start blinking with 1 second intervals.
The storage temperature set point is a field setting. Refer to the
chapter
"Field settings" on page 16
for a detailed description how to
set one or more field settings.
■
[b-03] set point: storage temperature (see figure
"Domestic
water heating modes" on page 7
) only valid if [b-02]=0.
■
[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. Therefor it is
recommended to use this function.
■
[b-04] Automatic maximum domestic hot water storage
temperature: default = 70°C.
Manual storage is deactivated automatically when the set point for
the domestic hot water storage temperature is reached. It can also be
stopped at any time by pushing the
button.
NOTE
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.
NOTE
■
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.
NOTE
Remark that the
icon will only be blinking
during effective operation.
During the operation it is always possible to
cancel the operation by pushing the
button
once.
Be aware that after pushing the
button, it is
possible that the permanently lit
icon still
displays, meaning that the reheat function is
enabled.
