Automatic Storage; Manual Storage - Daikin EKHBRD014AAV1 Operation Manual

Automatic storage

In this mode, the indoor unit will deliver hot water to the domestic hot
water tank based on the daily fixed pattern. This mode will continue
until the storage temperature set point is reached. During operation
of this mode, the w icon will be blinking with 1 second intervals.
Automatic storage is the recommended domestic hot water mode. In
this mode, water heats up during the night (when space heating
requirements are lower) until the storage temperature set point is
reached. The heated water is stored in the domestic hot water tank at
a higher temperature so it can fulfil the domestic hot water
requirements throughout the day.
Remark that the w icon will only be blinking during
NOTE
effective automatic storage operation. Presence of the
permanently lit w icon does not mean that automatic
storage is enabled, but only means that reheat is
enabled.
During operation it is always possible to cancel the
operation by pushing the w button once.
Be aware that after pushing the w button, it is possible
that the permanently lit w icon still displays.
The storage temperature set point and the timing are field settings.
Refer to the chapter "Field settings" on page 15
description 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.
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. Therefor it is
recommended to use this function.

require.
Start with a low domestic hot water storage
temperature set point, and only increase if you
feel that
temperature is not sufficient for your needs (this
depends on your water using pattern).

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.
