"Actual temperature" display
In the "Mixed water volume" menu, press
"Menu" once to access the "Actual tem-
perature" menu.
The "Actual temperature" symbol ap-
pears.
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 temperature.

Set temperature 1
Note
For hygiene reasons, never set the DHW temperature
below 50 °C.
Set temperature 1 is the DHW temperature to which the appliance
regulates if no external signal transmitter is connected and active.
Set temperature 1 is factory-set to 55 °C.
In the "Actual temperature" menu, press
"Menu" once to access the "Set temper-
ature 1" menu.
"Set temperature 1" symbol appears.
Adjust set temperature 1 from 20 °C to
65 °C using the "Plus" and "Minus" keys.
Note
Another way to adjust set temperature 1 is to press the
"Plus" or "Minus" keys from within the default display
(mixed water volume).
Frost protection
Only frost protection remains active if
you set the set temperature to below
20 °C using the "Minus" key. The display
shows "-- °C".

Set temperature 2
Note
For hygiene reasons, never set the DHW temperature
below 50 °C.
Set temperature 2 is the DHW temperature to which the appliance
regulates if an external signal transmitter is connected and active.
In the "Set temperature 1" menu, press
"Menu" once to access the "Set temper-
ature 2" menu.
The "External signal transmitter" symbol
appears.
Adjust set temperature 2 from 20 °C to
65 °C using "Plus" and "Minus".
Operation with external signal transmitter
Material losses
!
See "Permissible voltage range for external signal trans-
mitters" in the "Specification/data table" chapter.
As standard, the appliances feature the ability to assign a spe-
cific, individual set DHW temperature ("set temperature 2") to a
connected external signal transmitter, such as a PV system or a
low tariff transmitter.
This set temperature 2 is activated if the terminal connected to
the external signal transmitter receives a signal (see "Electrical
connection/external signal transmitter connection option" chap-
ter). While activated, set temperature 2 replaces the standard set
DHW temperature (set temperature 1).
If set temperature 2 is activated by the external signal transmitter,
this set temperature will then be active for at least 20 minutes.
If the external signal remains active after these 20 minutes have
passed, the compressor will run until the external signal drops
out. If not, the selected set temperature 1 is re-enabled.
When the relevant DHW set temperature has been reached, the
compressor switches off and remains off for a minimum idle time
of 20 minutes.
The following diagram illustrates the connections by means of a
sample signal sequence from an external signal transmitter.
