Note
The appliance has a second, higher set temperature
which is selected at the factory. This is activated when
there is an external switching signal. Set temperature 2 is
higher ranking than the standard set temperature while
there is an external switching signal.
An external signal transmitter for switching a separate set DHW
temperature (set temperature 2) can be connected to terminal
X3/1-2. In the delivered condition, terminal X3/1-2 is not assigned.
If this terminal is connected at the voltage stated in the specifica-
tion (see "Permissible voltage range, external signal transmitter")
(L to X3/1, N to X3/2), the appliance enables set temperature 2.

Following one-off activation (signal present for at least 1 min-
ute), set temperature 2 applies for at least 20 minutes. When
the relevant DHW set temperature has been reached, the com-
pressor 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.
Example:
- Water temperature = 55 °C
- Set temperature 1 = 50 °C
- Set temperature 2 = 65 °C
