2.4.8 Air capacity decision when Air capacity is running automatically.

When air capacity is running automatically, based on temperature adjusting sections, you shift the switch for air capacity, namely, enhanced, middle, and weak.

When air capacity is running automatically, shown following air capacity table.

H---High M----Middle L---Low

2.5 Defrost

When the high load precaution control operating, the priority is precaution control operating. Compressor is not off.

During the heat-making operation, communication of outdoor unit will deliver defrosting signal (I21=10), indoor unit will be based on defrosting controlling. It will continue until communication of outdoor unit delivers defrosting released signal (I21=01), indoor unit will be on heat-making operation directly. Air capacity will be of under the temperature controlling section of heat making.

2.6 Air capacity limited

During compressor operating, when the maximum speed of indoor fan be set middle or low speed, the upper limit of indication frequency shown respectively as following:

Frequency number of air capacity limit table:

	Limiting frequency variable	Limiting frequency
Air capacity middle limit	FQLIMMD	90Hz
Air capacity low limit	FQLIMLO	52Hz
Upper and down limit of fresh	FUPHEAL	30Hz
air capacity frequency

Estimate the limiting frequency condition in heat mode; first, estimate it whether is the limiting frequency condition of set low fan or health fan. If there have set low fan, health fan or both of them, to
