 “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.
In the "Actual temperature" menu, press
"Menu" once to access the "Set temper-
ature 1" menu.
"Set temperature1" symbol appears.
You can change the value using the
"Plus" and "Minus" keys. Setting range:
20 - 65 °C
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 tempera-
ture2" menu. The "External signal trans-
mitter" symbol appears.
You can change the value using the
"Plus" and "Minus" keys. Setting range:
20 - 65 °C
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 specific,
individual set DHW temperature (“set temperature2”) to a con-
nected external signal transmitter, such as a PV system or a low
tariff transmitter. This set temperature 2 is activated if the termi-
nal connected to the external signal transmitter receives a signal
(see “Electrical connection/external signal transmitter connection
option” chapter). 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 the 20minutes have
passed, the compressor will run until the external signal drops
out or set temperature2 is reached. Afterwards, the selected set
temperature1 is activated again.
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.
