Field Setting ESIE09-08B
102 Test Operation
[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 o
f 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/AD: [b-04]
Note : The temperatures for weather dependent domestic water heating
(see figure) are fixed and can
n
ot 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.
