5.3 Power Saving Functions from Wired Controller
The power saving functions are available from the wired controller COW01 as follows.
5.3.2 Water Source 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.
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
maximumpowercorrectly.
2. The cooling capacity will be 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 interrupter and equipment fault.

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.
