"Rapid heat-up" button

Note
To start rapid/comfort heat-up with the "Rapid heat-up"
button, the start screen must be displayed.
Press the "Rapid heat-up" button for two
seconds.
The "heat pump" and "electric emergen-
cy/booster heater" symbols appear.
4.3.1 Rapid/comfort heat-up
Normally, the "Rapid heat-up" key is used to enable rapid/comfort
heating, which lets you cover an unexpectedly high DHW demand
without changing any of the appliance's standard settings.
If quick/comfort heat-up is activated manually by pressing the
relevant key, the heat pump and the electric emergency/booster
heater will start in parallel, irrespective of the selected set tem-
perature, and will remain active until the DHW temperature in the
cylinder has reached 65 °C.
If the water temperature in the upper cylinder section rises by a
hysteresis value above the set temperature on the cylinder top
sensor, the electric emergency/booster heater is switched off.
The electric emergency/booster heater remains in standby mode
until the set temperature has been reached throughout the DHW
cylinder. A flashing "electric emergency/booster heater" symbol
indicates that the electric emergency/booster heater is in standby
mode.
The rapid/comfort heating function remains active until a temper-
ature of 65 °C has been achieved throughout the DHW cylinder
(comfort heating). The appliance then automatically switches back
to the previously set parameters.
Note
The "electric emergency/booster heater" and "heat pump"
symbols are displayed until the rapid/comfort heating
terminates.
Note
To end rapid/comfort heat-up, press the "Rapid heat-up"
button for two seconds.
4.3.2 Emergency mode
If the appliance is faulty, you can use emergency mode to activate
the electric emergency/booster heater.
Following a DHW demand, the appliance checks the temperature
increase every 15 minutes. If the temperature increase is <0.25 °C
during each measurement interval until the end of the maximum
temperature increase time (see "Specification" chapter), the ap-
pliance switches off the compressor.
The "service/fault" symbol flashes on the display and a fault code
indicates that the appliance is not heating.

Press the "Rapid heat-up" button for two
seconds.
The "Electrical emergency/booster heat-
er" symbol appears. The "Service/fault"
symbol flashes.
After the "Quick heat-up" key has been pressed, the indicated fault
code increments by a value of 256, as the fault codes are added
together (see fault code table in the "Troubleshooting" chapter).
"Service/fault" symbol continues flashing. The electric emergency/
booster heater is activated.
The current set temperature (set temperature 1 or set temper-
ature 2) is ignored. In emergency heating mode, the appliance
operates with a fixed set temperature. In the upper cylinder sec-
tion, the DHW is heated up to 65 °C by the electric emergency/
booster heater.
Following one-time enabling of this function by means of the
"Quick heat-up" key, this function remains enabled for 7 days.
Following 7 days of emergency operation the electric emergency/
booster heater is disabled. The fault code shown on the display
decrements by 256.
If you press the "Rapid heat-up" button again for two seconds
within the 7 days of emergency heating mode, the 7-day runtime
for emergency heating mode will restart.
If the 7-day runtime for emergency heating mode has expired,
you can restart emergency heating mode for a further 7 days by
pressing "Rapid heat-up".
Pressing the "Rapid heat-up" button only enables emergency heat-
ing mode if a fault with fault code 8 had previously occurred. In
standard mode, pressing the "Rapid heat-up" button only triggers
one-off heat-up of the DHW cylinder.
Emergency mode is no longer active after an interruption to the
power supply. The appliance tries again to heat with the heat
pump. You can avoid having to wait until the temperature increase
time has elapsed (see chapter "Specification") by starting manual
emergency heating mode.
Manual emergency heating mode
If a fault has occurred and no fault code is displayed, you can
activate emergency heating mode.
Keep the "Plus" and "Minus" buttons
pressed. In addition, press the "Menu"
button and keep all three buttons
pressed for 5 seconds.
The "Electrical emergency/booster heat-
er" symbol appears. The "Service/fault"
symbol flashes.
