4.3.2 Emergency mode

If the appliance is faulty, you can use the 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" key for two
seconds.
The "electrical emergency/booster heat-
er" symbol appears. 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" key 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 "Quick heat-up" key only enables emergency mode if
an error with fault code 8 occurred previously. In standard mode
pressing the "Quick heat-up" key only triggers one-time heat-up
of the DHW cylinder.
Emergency mode is disabled by an interruption of the power sup-
ply. The appliance tries again to heat with the heat pump. You
can avoid having to wait until the temperature increase time has
elapsed (see "Specification" chapter) by starting manual emer-
gency heating mode.

button and keep all three buttons
pressed for 5 seconds.
The "electrical emergency/booster heat-
er" symbol appears. Service/fault symbol
flashes.

Appliance Care and maintenance tips
components
Casing Use a damp cloth to clean the casing sections. Never use
abrasive or corrosive cleaning agents.
Air intake Clean the air intake grille and air discharge grille every six
grille / air dis- months. Cobwebs or other kinds of contamination can re-
charge grille strict the air supply to the appliance.
DHW cylinder The DHW cylinder is equipped with a maintenance-free im-
pressed current anode to safeguard it against corrosion. The
power supply must not be interrupted while the appliance is
filled with water to enable the impressed current anode to
provide protection. Otherwise there is a risk of corrosion.
Electric emer- Have the electric emergency/booster heater descaled from
gency/booster time to time. This will extend the service life of the electric
heater emergency/booster heater.
appliance Have the safety assembly and the evaporator checked regu-
larly by a qualified contractor.
Condensate Undo the condensate drain. Check that the condensate drain
drain is clear and remove any dirt from the condensate drain con-
nection.
Scaling
Almost every type of water will deposit limescale at high temper-
atures. This settles inside the appliance and affects both perfor-
mance and service life. A qualified contractor who knows the local
water quality will tell you when the next service is due.
