DHW
15 ... 60 °C(80 °C): set the required DHW
temperature. The temperature depends on
the temperature of the buffer cylinder.

Start
If the DHW circulation pump is active via the

DHW circ.
or if it is permanently switched on (DHW
circulation pump operating mode: On), this
setting affects the DHW circulation pump
operation.
1 x 3 minutes/h ... 6 x 3 minutes/h: the DHW
circulation pump goes into operation once ...
6 times per hour for 3 minutes. The default
setting depends on the installed heat
generator.
Permanently: the DHW circulation pump is
continuously in operation.
Circulation
Yes | No: the circulation can be switched on

Daily heat-up
Yes | No: the entire DHW volume is
automatically heated up daily at the same
time to 60 °C.

Fault display
Yes: if a fault develops in the freshwater
system, the output is activated for a fault
display. If the fault display is active, only a
3-wire 3-way valve can be connected to
terminal VS1, PS2, PS3.
No: if a fault develops in the freshwater
system, the output is not activated for a fault
display (always de-energised).
Inverted: the fault display is activated but the
signal is inverted. This means that the output
is energised and switched to the de-
energised state when a fault is displayed. If
the fault display is active, only a 3-wire 3-way
valve can be connected to terminal VS1,
PS2, PS3.
Keep hot
Yes | No: activation of heat maintenance
function. If the freshwater system is far away
from the buffer cylinder, it can be kept hot by
means of circulation.
