the buffer with a flow temperature of 61 °C, and
from the solar system with 74 °C.
3 Temperature of the hot water tank.
The temperature in the lower area of the tank only
appears if an additional temperature sensor is
installed.
4 [Load immediately] button.
Immediate charging of the hot water, independent
of the set time slots.
5 [Settings] button.
In this menu, the time window can be set, for
example.
[Load immediately] button
This button causes the hot water to be charged
to the highest set temperature of all time slots
and days of the week if the current temperature
has dropped below [Switch-on diff.], ignoring the
current time slot. When active, the button is highlighted
in yellow
.
Mode of operation
In the settings menu ( button), the time window for
charging the hot water and the desired hot water
temperature can be set. See chapter
5.4.1 "Setting the
hot water charging times" .
Within the charging times, the hot water is charged to
the set hot water temperature (for example: 60 °C).
The charge starts as soon as the current hot water
temperature is lower than the set hot water
temperature by the adjustable difference [Switch-on
diff.].
Example:
In the time window, the hot water temperature is set to
60 °C. The difference [Switch-on diff.] is 15 °C.
=> Charging starts as soon as the hot water
temperature drops to 45 °C, and it ends as soon as the
hot water has reached 60 °C.
If an additional temperature sensor [] is installed
for the lower part of the hot water tank, charging
ends as soon as this sensor has reached the configu-
rable temperature [HW bottom off].
