EKHBRD011~Y1
Indoor unit for air to water heat pump system and options
4PW60971-1
Automatic storage
In this mode, the indoor unit will deliver hot water to the domestic hot
water tank based on the daily
fi
xed 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 ful
fi
l the domestic hot water
requirements throughout the day.
The storage temperature set point and the timing are
fi
eld settings.
Refer to the chapter "Field settings" on page 15 for a detailed
description how to set one or more
fi
eld settings.

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.

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.

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 suf
fi
cient 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 suf
fi
cient 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.
