Contractor level parameters
The boiler circuit pump operates constantly if the outside
temperature stays below the selected value. The burner starts and
heats the boiler to a min. of 38 °C, if the boiler water temperature
falls below +5 °C.
Note:
Only change the factory setting if you can ensure that the heating
system and its components will not freeze up at low outside
temperatures.

Setting range: 0 / 1
Individual setting: ______
The boiler circuit pump is switched OFF during DHW cylinder
heating with DHW priority (0) . The boiler energy will then be
used exclusively for heating the DHW cylinder. The cylinder
primary pump will only start, if the boiler water temperature is
5 °C higher than the actual cylinder temperature. The burner
shuts down and the heating circuit pump is started, as soon as
the cylinder has reached its set temperature. The cylinder primary
pump runs on for the maximum period selected under parameter
HG19 (cylinder primary pump run-on time).
The heating circuit pump continues to operate in parallel DHW
mode (1) . The cylinder primary pump starts, if the boiler water
temperature is 5 °C warmer than the cylinder temperature. The
cylinder is fully heated up when the cylinder has reached the
selected water temperature. The cylinder primary pump runs on
for the maximum period selected under parameter HG19 (cylinder
primary pump run-on time).
In the parallel DHW mode (1), the heating circuit can temporarily
be operated at a higher temperature.

°C
Factory setting: 65 °C
Setting range: 60 to 80 °C
Individual settings: _________
This temperature can be enabled at 80 °C, if for commercial
reasons a higher DHW temperature is required.
If pasteurisation has been activated (BM), the DHW cylinder will
be heated to the selected maximum DHW temperature during the
fi rst cylinder heating of the day.
Take adequate measures to prevent scalding. Parameter HG22
(maximum boiler water temperature) should be set at least 5 K
higher than the selected maximum DHW temperature.
