The storage temperature set point is a 

fi

eld setting. Refer to the

chapter "Field settings" on page 15 for a detailed description how to
set one or more 

fi

 Status: de

fi

nes 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 

w

 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
minimum value is reached. The domestic water heating will continue
until the reheat maximum temperature is reached.

operation of this mode the 

w

  icon will be blinking rapidly with 0.5

second intervals. 

The disinfection temperature set point is a

Activating the emergency mode will stop the heat pump
operation. The pump of the indoor unit will be started, but
heating itself is done by the heater kit. If there are no error
conditions in leaving or returning water thermistors, the heater
kit can start to follow emergency operation.
