4.3.8 Demand Function Setting
Press “PSW3” and select the setting condition “0” to “5”, so that the demand function setting “ ” can be set. This function
is available by setting to “1” for the demand current control without inputting the signal to the external input terminal on the
outdoor unit PCB. The table below is shown for the limit of the operating current for this function.
NOTE:
In the case that the demand current control by external input is set and the external input signal is available, this function is
not available even when the demand current control by external input signal is performed.

● Demand Control
Adopting self-demand function, which drastically decreases power consumption, has largely improved energy saving.
< NOTES at Facility Design >
1. The demand current control (%) is value criterion. The value used for this control is calculated from the current, and
therefore is dierent from the value indicated by a wattmeter. If it is required that the maximum power consumption is
managed precisely, a eld-supplied demand controller should be used.
2. The actual value may temporarily be higher than the indicated value shown above depending on the operating control
conditions such as protection control.
Maximum efficiency is secured
within the power setting range.
