The auto, on, and off operating modes are possible
for the connected domestic hot water cylinders and
the circulation circuit:
The maximum DHW temperature determines the
temperature to which the domestic hot water cylin-
der should be heated.
The
minimum DHW temperature determines the
limit below which the domestic hot water cylinder is
heated.
Note: The maximum DHW temperature is only dis-
played when the auxiliary hot water heating is ena-
bled (see Menu C7). Without electric auxiliary heat-
ing, the DHW temperature is limited by the pressure
sensor control shut-off in the cooling circuit and
cannot be adjusted!
