Description
1 When temperature of the
exchanger drops below
5°C, the compressor speed
is reduced. (P zone)
2 When temperature of the
indoor heat exchanger rises
exchanger rises in the range
from 6°C to under 7°C, the
compressor speed is kept.
(Q zone)
3 When temperature of the
indoor heat exchanger rises
to 7°C or higher, the
capacity control operation
returns to the usual control
in cooling operation.
