Terminology

Constant temperature operation
In constant temperature operation, the heating water is
constantly (continuously) heated to the selected boiler
water temperature.
Heating water temperature
The temperature of the heating water that flows to the
radiators (roughly equal to boiler water temperature).
Boiler water temperature
The heating water in the boiler (boiler water) is heated
to the temperature set at the control unit. This temper-
ature is referred to as boiler water temperature.
Open flue operation
The combustion air is drawn from the room where the
boiler is installed.
Room sealed operation
The combustion air is drawn from outside the building.
Room temperature-dependent operation
A room temperature controller captures the room tem-
perature and compares this with the required room
temperature you set. If the room temperature is lower
than the required value, the boiler is switched on; if the
room temperature is higher than the required value,
the boiler is switched off.
Make any settings on the connected room temperature
controller using the relevant operating instructions.

Information on disposal

Disposal of packaging

You heating contractor will dispose of the packaging of
your Viessmann product.

Final decommissioning and disposal of the heating system

Viessmann products can be recycled. Components
and fluids from your heating systems are not part of
ordinary domestic waste.
Please contact your heating contractor in connection
with the correct disposal of your old system.

Note
The heating water temperature must be set high
enough in order to achieve the required room tempera-
ture.
Safety valve
Safety equipment that must be installed in the cold
water pipe by your heating contractor. The safety valve
opens automatically to prevent excess pressure in the
DHW cylinder.
Drinking water filter
A device that removes solids from potable water. The
drinking water filter is installed in the cold water pipe
upstream of the DHW cylinder or the instantaneous
water heater.
Flow temperature
The temperature of the heating water that flows to the
radiators (in the flow line). Accordingly, the tempera-
ture of the heating water that flows from the radiators
to the boiler (in the return line) is referred to as return
temperature.
Weather-compensated operation
In weather-compensated mode, the flow temperature
is controlled according to the outside temperature. This
means that no unnecessary heat is generated in order
to heat the rooms to the required room temperature
you selected.
The outside temperature is captured and transmitted to
the control unit by a sensor fitted outside the building.
DE: Packaging waste is channelled for recycling to a
certified disposal contractor in line with statutory
regulations.
AT: Packaging waste is channelled for recycling to a
certified disposal contractor in line with statutory
regulations. Use the ARA statutory disposal sys-
tem (Altstoff Recycling Austria AG, licence num-
ber 5766).
DE: Operating fluids (e.g. heat transfer medium) can
be disposed of at municipal collection points.
AT: Operating fluids (e.g. heat transfer medium) can
be disposed of at municipal collection points
(ASZ).
