(9) Setting the capacity control ratio using analog signal input
• When dip switch SW2-7 is set to ON (Enable external input) and item code 1051 is set to "1", the capacity control
ratio varies with the type of analog input signal.
• When the water temperature setting input signal type is set to 0 (4-20 mA)
• External analog input signal of 4-6 mA: 0%
• External analog input signal of 18-20 mA: 100%
• External analog input signal of between 6 and 18 mA: the percent will be linearly interpolated.

0%
• When the water temperature setting input signal type is set to 1 (0-10 V)
• External analog input signal of 0-1 V: 0%
• External analog input signal of 9-10 V: 100%
• External analog input signal of between 1 and 9 V: the percent will be linearly interpolated.
Load ratio

0%
• When the water temperature setting input signal type is set to 2 (1-5 V)
• External analog input signal of 1-1.5 V: 0%
• External analog input signal of 4.5-5 V: 100%
• External analog input signal of between 1.5 and 4.5 V: the percent will be linearly interpolated.
Load ratio
100%
0%
• When the water temperature setting input signal type is set to 3 (2-10 V)
• External analog input signal of 2-3 V: 0%
• External analog input signal of 9-10 V: 100%
• External analog input signal of between 3 and 9 V: the percent will be linearly interpolated.

*%: When the compressor frequency drops below 30 Hz, the compressor stops.
The frequency value that causes the compressor to stop varies depending on the outside temperature and water temperature.
