Setting Switching Times Of The Auxiliary Output (E.g. Dhw Circulation Pump) - Viessmann vitocal 300-g Operating Instructions Manual

Selecting constant DHW heating
The operating mode for the selected time
period (15 min block, top left) is dis-
played by bar height and number (1, 2, 3
or 4).
■ In "TOP" operating mode, a reduced
volume of DHW is made available.
Only a part of the DHW cylinder is
heated to the "Set DHW temp." tem-
perature.
■ In "STANDARD" operating mode, the
entire DHW volume in the DHW cylin-
der is heated to the "Set DHW
temp." temperature.
■ In "STANDARD" and "TEMP. 2"
operating modes, the lower cylinder
temperature sensor is used as a shut-
down criterion (if installed).
■ In "TEMP. 2" operating mode, "Set
temp. 2" is selected as the constant
DHW temperature. The "Set temp.
2" is higher than the "Set DHW
temp." temperature. This is connec-
ted to "Pasteurisation" (see
page 34).
