The capacity limit can be
selected by the external
input terminal (CN133) when
operating with the "Energy

Saving Peak Cut function."

The lower the level, the more
the effect of energy saving, but
the cooling/heating performance
will also drop.
If the cooling/heating
performance becomes
insufficient when the low noise
l
mode is set, it is possible to
- set "capacity priority" that
¡
*1 automatically cancels the low
noise mode (once performance
is restored, the mode will
automatically return to the low
noise mode).

NOTE:
In the VRF system with multiple outdoor units,
the recovery operation is unable to activate
if any one of the outdoor units, in which all
compressors are malfunctioned, breakdowns
due to the uncontrollable pressure equalization
between the outdoor units.
If in the event that the recovery operation were to
operate under the malfunctioned condition, it will
lead to accumulation of refrigerant in the faulty
outdoor unit.
