8. Appliance description
For outdoor installation the appliance offers additional frost pro-
tection of the heating water pipes. The integral frost protection
circuit starts the heating circuit pump in the heat pump circuit
automatically at +8°C condenser temperature, and thereby en-
sures circulation in all water-filled sections.
The heat pump starts automatically when the temperature in the
heat pump circuit drops below +5°C.
In dual mode operation, return water from the second heat gen-
erator may flow through the heat pump. The return water tem-
perature must not exceed 60 °C.

9. Preparations
9.1 Sound emissions
The appliance is louder on the air intake and air discharge sides
than on the two enclosed sides. Observe the following information
when selecting the installation location.
Note
For details regarding the sound power level, see chapter
"Specification / Data table".
9.1.1 Sound emissions for outdoor installation
- Lawn areas and shrubs help reduce the spread of noise.
- Noise propagation can also be reduced through dense pali-
sades or similar.
 Ensure that the air intake direction is the same as the dom-
inant wind direction. Air should not be drawn in against the
wind.
 Never direct the air intake or discharge towards noise-sensi-
tive rooms of the house, e.g. bedrooms.
 Avoid installation on large, echoing floor areas, e.g. tiled
floors.
