(2) Energy saving control for outdoor unit
For the energy saving control for the outdoor unit, select a time portion to be applied to the energy
saving control items listed in Table 9-2 from 0/3/6/9/15/30 minutes. By dividing those items by the group
numbers in the operation block evenly, the energy saving control is applied.
The rotated operation is applied to the outdoor units starting from that with smaller address.
[In case of the energy saving control of 3 outdoor units for 15 minutes for example]
0 3
1 Times of rotation:
For the control of 15 minutes, 3 minutes control is applied for 5 times (= 15 min./3 min.).
2 Cycles of rotation:
From the times of rotation in 1, the cycle of rotation for 30 minutes is to be 6 minutes (= 30 min./5 times)
3 Intervals of rotation:
From the cycles of rotation in 2, the rotation interval of each group in a block counts for 2 minutes (= 6 min./3 groups).

Figure 9-4 Example of outdoor unit energy saving control
The capacity saving control is a control to suppress the maximum value of the outdoor unit.
Therefore, no energy saving effect can be obtained under the setting to 80% if the operation is
conducted with the capacity below 80%.
Capacity
80%
In the case of the energy saving control, capacity saving control is applied to the outdoor unit
individually.
For this reason, be careful that the control will be applied to the indoor unit being not targeted if the
group setting is made by stepping over the refrigerant system.
In the case of capacity saving control to the outdoor unit, control for a short time may not provide a
normal effect. Control for 30 or 15 minutes is recommended.
For Multi S, set to "No control" so that the capacity saving control will not be applied to the outdoor
units.
