Description

1)When temperature of the indoor heat exchanger drops below 5°C, the compressor speed is reduced. (P zone)

2)When temperature of the indoor heat 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.

(R zone)

1)When temperature of the indoor heat exchanger rises in the range from 50°C to 55°C, the compressor speed is kept.

(Q zone)

When temperature of the indoor heat exchanger drops in the range from 46°C to under 55°C, the compressor speed is kept. (Q zone)

2)When temperature of the indoor heat exchanger rises to 55°C or higher, the compressor speed is reduced. (P zone)

3)When temperature of the indoor heat exchanger does not rise to 50°C, or when it drops below to 46°C, the capacity control operation returns to the usual control in heating operation.
