i Information
Data on sound pressure levels refer to 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.
