(a) Summary
1) Capacity control
Capacity control is within the range shown above. If demand capacity of the indoor units exceeds the maximum capacity
of the outdoor unit, the demand capacity will be proportionally distributed.
2) Outdoor unit frequency control (30 ~ 104Hz)
The decision frequency is based on the total indoor demand frequency as follows:
Indoor demand frequency total
30 Hz or less
More than 30 Hz, but 104 Hz or less
More than 104 Hz
Note (1) The total indoor demand frequency is based on the value for each of the units shown in item (b).
(b) Mode switching
Within the selected mode, the unit operates using the values shown below which were obtained by multiplying a conversion
coefficient to the indoor unit demand frequency.
