ESIE09-08A Field Setting
Test Operation 109

[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 summertime), the cold supply water to the
mixing tap (e.g. shower, bath) will also have a higher temperature. This makes that the temperature of
the hot water from the domestic hot water tank may be lower to reach the same water mixing
temperature from the shower or bath mixing tap. In this way, with a lower domestic hot water tank
temperature setting the comfort level can be kept the same but with a lower energy consumption.
(*) For EKHBRD*AA: Fixed at 70°C
For EKHBRD*AB/AC: [b-04]
Note : The temperatures for weather dependent domestic water heating (see figure) are fixed and can not be
changed.

[b-03] Set point: storage temperature (see figure above)
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.
