Heating up DHW once
1)
To save energy, during day mode DHW is
only reheated automatically when its
temperature falls 5 °C below the set DHW
temperature.
If you need large amounts of hot water one
evening or outside the set times for day
mode, you can heat up the DHW.
This function is not available with boilers
with UBA1.x.
You can see by the lighting-up of the LED of the
button, that the DHW temperature has fallen
below the set value

Heat-up starts, and is later terminated
automatically.
If no heating is necessary (because the water is

circulation pump will start (if fitted) to transport
the hot water more quickly to the draw-off points.
B If you want to stop the heating process:
press again.
Heating up DHW regularly If you regularly need large amounts of hot water
outside the set times for day mode, you can set a
separate program for DHW (Æ page 38).
