 Time set for the "Runtime-dependent rapid heat-up"
function
Note
In appliances with no electric emergency/booster heater,
this parameter has no function.
To avoid increased power consumption, only reduce the facto-
ry-set time for runtime-dependent rapid heat-up if necessary. See
chapter "Specification/ Appliance parameters".
Set the runtime using the "Plus" and
"Minus" buttons. After the set number of
hours, the appliance checks whether the
set temperature has been reached. If this
is not the case, the appliance switches on
the electric emergency/booster heater.

 Change units
You can select whether the temperatures and the volume details
are displayed in SI units or US units. If you select 1, the values are
displayed in degrees Celsius and litres. If you select 0, the values
are displayed in degrees Fahrenheit and gallons.
Press the "Menu" button until "SI" ap-
pears on the display.
Using the "Plus" and "Minus" buttons, set
whether the display should use SI units
(1) or US units (0).
 Charge level
Increasing this value increases the minimum available amount of
DHW. The effect corresponds to a virtual shift of the temperature
sensor downwards. This results in a faster recovery at the expense
of higher energy consumption and reduced efficiency. Reducing
this value has the opposite effect and results in a longer recovery
at the expense of DHW availability.
DHW heating is started when the available mixed water volume
decreases to the percentage of the maximum mixed water volume
set in the "Charge level" parameter.
Factory setting
Charge level WWK 222 (H) % 56
Charge level WWK 302 (H) % 64
The displayed mixed water volume is based on a mixed water
temperature of 40°C. At water temperatures below 40°C (±1K),
the mixed water volume is not calculated or displayed.
A further start condition, which overlaps with the charge level
start conditions, is the reduction of the temperature captured by
the cylinder top sensor to 6K below the active set temperature.
Press the "Menu" button until an "L" fol-
lowed by a number appears on the dis-
play.
You can change the value using the "Plus"
and "Minus" buttons. Setting range: 30
- 100 %

Do not change this parameter unless instructed by a Stie-
bel Eltron representative.
 Fault code
If the "Service/fault" symbol is illuminat-
ed or flashes, you can call up the fault
code using the "Menu" button. This menu
remains disabled if no fault has arisen.
See chapter "Troubleshooting/ Fault codes".
 E fault code
A fault code preceded by E appears if the fault relates to the re-
frigerant circuit.
