i
Information
Data on sound pressure levels refer to operation at
full load at a distance of 10 m (free space). Sound
pressure and sound power levels are given +/-3
dB(A).
i
Information
Silent mode offers four separate time windows
during which the outdoor unit can be operated
with reduced sound levels. It is set via the OTE
controller.
