Measured value display: The measured values are
displayed in the status menu. The temperature of
the cold water probe and the operating hours of
the distribution valve are displayed after the fresh
water values.
Temperature of the cold water probe: The corre-
sponding minimum/maximum value is displayed
when "SET" is pressed.

Operating hours of the distribution valve: When
"SET" is pressed, the delta value and the cumula-
tive value of the operating hours are displayed
alternately.

tive value of the operating hours
In cascade operation, this function may only be
activated for the master controller. This func-
tion is blocked in the slave controller. The slave
controller sends its cold water temperature to
the master controller. If both stations are
active, the higher cold water temperature is
used as the switching value.

Sliding hot water temperature
Adjusts the domestic hot water target temperature
to the temperature level of the buffer tank for pre-
heating systems that are discharged from the
Buffer tank without re-heating
(Tww target = T
VL
- 5 K).
This function works according to fixed parameters.
No further settings are required. If this function is
active in operation, this is symbolised by a flashing
temperature.
The function can only be activated or deactivated.

In cascading operation, this function is recom-
mended only in exceptional cases because
high temperature fluctuations occur at the dis-
pensing connection when switching the mod-
ules. If the function is selected despite this, it
must be activated in the master and slave con-
trollers. The function works independently in
each of the controllers.
