EXTERNAL INPUT/OUTPUT AND FUNCTION SETTING

5.5 Functions from Wired Controller

The functions are available from the wired controller CIW01 as follows.
Regarding setting procedure, refer to the "Operation Manual" for the Wired Controller.
5.5.1 Power Saving Function
NOTE:
The following functions (1)~(3) cannot be operated at the same time.
(1) Outdoor Unit Capacity Control
The demand function setting can be controlled from wired controller. Select from "Peak Cut Control"
and "Moderate Control" according to the situation.
"Peak Cut Control" Function
The peak cut control reduces the power consumption range when it exceeds the value of the power
saving setting.
NOTES:
1. The power set value (%) is just a criterion. The power set value for this function is different from the
actual power value in precision. Use the demand controller (option) when it is necessary to manage
the maximum power correctly.
2. The cooling capacity is decreased according to the power saving setting value for the reducing of
compressor motor revolution.
3. The actual electrical power consumption may be higher than the value displayed on the screen under
certain operating condition such as protective control.
4. This function is used to inhibit power consumption of the operating. Do not use it for minimize the
capacity of current and the voltage for the power circuit, power supply wiring, GFCI, transformer, etc. It
may cause actuation of the interrupter and equipment fault.
5. Power consumption depends on connected outdoor unit.
"Moderate Control" Function
The moderate control moderate the air conditioning capacity not to exceed the value of the power
saving setting.
NOTES:
1. The moderate control setting value can be set from 40% to 100% of regular capacity by every 10%.
2. The setting value is just a criterion. It might be different according to the actual service condition and
operating condition.
