6.5.1 Setting the hot water temperature
You can change the DHW temperature:
Hold the DHW button down and select the desired DHW temperature with the
dial.
Release the DHW button. The newly-selected DHW temperature is saved within
approximately 2 seconds. The permanent display will then appear again.
6.5.2 Single DHW charge
If the "DHW" LED lights up, only a limited amount of hot water remains in the
DHW storage tank. Should you want a larger amount of DHW, proceed as
follows:
Press "DHW".
The "DHW" LED flashes, and a single DHW charge is started.
Depending on the size of the storage tank and the boiler output, DHW will be
available after approximately 10 to 30 minutes. With instantaneous water
heaters or combination boilers, DHW is available almost immediately.
WARNING!
RISK OF SCALDING
from DHW.
Hot water temperatures above 122 °F (50 °C) can cause scalding almost
immediately.
z Do not draw off DHW unmixed.
z Ensure that a thermostat-controlled mixing valve is installed as protection
against scalding.

USER NOTE
For thermal disinfection, the DHW will be heated to at least 140 °F (60 °C) once
or twice per week to kill off possible bacteria (e.g. legionella).
