15 - FAN SMART ACOUSTIC SYSTEM™
15.1 - Function
The CLIMATIC™ 60 controls the fan speed limit by the Smart Acoustic System™ which allows progressive
adaptation of the unit to the building load while respecting the noise level constraints and the operating limits.
15.2 - Description
The maximum sound level and the fan strategies can be adjusted according to the schedule mode in order to
benefit from the different modes “High performance”, “Quiet” and “Quiet++” operation as well as in heating or
cooling mode.
The acoustic mode offers 2 possibilities to manage the condenser fan:
15.2.1 - “Quiet”
In this mode, the fan capacity is limited according to the sound level desired. For fan using low / high speed, the
high speed is locked. In case of condensing temperature too high, the CLIMATIC™ 60 unlocks the limit or the high
speed to prevent from unloading compressor.
