4.2.1 Symbols
Symbol Description
Mixed water volume: The currently available amount of mixed
water at 40°C and at 15°C cold water temperature is shown.
Set temperature adjustment: Subject to intake temperature and
hot gas temperature, the appliance may temporarily reduce the set
temperature to the actual value captured by the integral sensor.
The appliance displays the "set temperature adjustment" symbol
and blocks DHW heating until the actual temperature captured by
the integral sensor is below the temporary set value by a value
equal to the reduced start hysteresis. DHW heating is then re-ena-
bled and the originally selected set temperature is again applied.
Actual temperature: The current actual temperature is shown. The
actual temperature indicates the temperature in the upper section
of the DHW cylinder and largely corresponds to the outlet temper-
ature.
Set temperature
External signal transmitter: Set temperature2 is the DHW tempera-
ture to which the appliance regulates if an external signal transmit-
ter is connected and active.
Standby: The symbol flashes, if the appliance PCB and load (com-
pressor) are separately supplied with voltage. This connection
option is required, if the appliance is to be operated via switchable
sockets in an energy management system (see "Electrical connec-
tion" chapter) for example.
Electric emergency/booster heater: This symbol indicates the pres-
ence of a demand on this component. This symbol being displayed
does not necessarily mean that the electric emergency/booster
heater is in operation.
Heat pump: This symbol indicates the presence of a demand on
this component. This symbol being displayed does not necessarily
mean that the compressor is running.
Defrost active
Symbol Description
Service/fault: Notify your qualified contractor if the "Service/fault"
symbol appears on the display. Continuous illumination of the sym-
bol indicates that the fault is not preventing appliance operation.
A flashing "Service/fault" symbol indicates that water is not being
heated and that it is essential you notify your qualified contractor.
Switching the appliance to emergency mode is a special case. The
electric emergency/booster heater will then heat the water despite
the flashing "Service/fault" symbol.
The symbols for electric emergency/booster heater and heat pump
are displayed when there is a demand for these appliance compo-
nents. These symbols being displayed does not necessarily mean
that the electric emergency/booster heater and the heat pump
are running.
Example: The appliance is in rapid/comfort heat-up mode. The
electric emergency/booster heater switches off when the temper-
ature in the upper cylinder section has reached 65°C. The heat
pump has not yet heated the lower section to 65°C and the rapid/
comfort heat-up function has therefore not been terminated yet.
The electric emergency/booster heater symbol is displayed until
the rapid/comfort heat-up function has terminated.
