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 eld setting. Refer to
"4.15. Field settings" on page 19 for a detailed description how to set
one or more eld settings.
[b-03] set point: storage temperature (see gure "Domestic
water heating modes" on page 8) only valid if [b-02]=0.
[b-02] Status: denes 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.

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.
Reheat
This mode will prevent the domestic hot water from cooling down
lower than a certain temperature. When enabled the indoor unit will
deliver hot water to the domestic hot water tank when the reheat
