Reduced room temperature
For periods when you will be absent or
during the night, select the reduced room
temperature. Set the periods using the
time program for central heating. During
these periods, the interior is heated to a
reduced room temperature.
Safety valve
A safety device that must be installed in
the cold water pipe by your heating con-
tractor. The safety valve opens automat-
ically to prevent excess pressure in the
DHW cylinder.
Set temperature
Default temperature that should be
reached, e.g. set DHW temperature
Drinking water filter
A device that removes solids from pota-
ble water. The drinking water filter is
installed in the cold water pipe upstream
of the DHW cylinder or the instantaneous
water heater.
Weather-compensated mode
In weather-compensated mode, the
heating flow temperature is regulated
according to the outside temperature.
This means that no more heat is gener-
ated than is actually required to heat the
interior to the set room temperature you
selected.
The outside temperature is captured and
transmitted to the control unit by a sen-
sor fitted outside the building.
Efficient and clean operation
To ensure efficient and clean operation
of your heating system, please note the
following:
■ Only qualified and trained personnel
may install and adjust the system.
■ Only use the fuels specified in our
operating instructions (see chapter
"Ordering fuel"). This is essential for
ensuring clean, efficient and reliable
operation of your heating system.
■ Regularly carry out the recommended
maintenance and cleaning work on
your system. For details, see chapter
"Maintenance and cleaning" in the
operating instructions. This guaran-
tees not only the operational reliability
of the heating system and its safety
equipment, but also its efficient and
clean operation. For the best support
of your heating system, we recom-
mend taking out a maintenance con-
tract.
