 When the water temperature setting input signal type is 0-10 V
• External analog input signal of 0 V: Preset temp. A
• External analog input signal of 10 V: Preset temp. B
• External analog input signal of between 0 and 10 V: the preset temperature will be linearly interpolated.

Preset temp A
 When the water temperature setting input signal type is 1-5 V
• External analog input signal of 1 V: Preset temp. A
• External analog input signal of 5 V: Preset temp. B
• External analog input signal of between 1 and 5 V: the preset temperature will be linearly interpolated.

 When the water temperature setting input signal type is 2-10 V
• External analog input signal of 2 V: Preset temp. A
• External analog input signal of 10 V: Preset temp. B
• External analog input signal of between 2 and 10 V: the preset temperature will be linearly interpolated.

6. Setting the capacity control ratio using analog signal input
When dip switch SW5-7 is set to ON (Enable external input), SW5-8 is set to ON, and SW5-9 is set to OFF, the capacity control
ratio varies with the type of analog input signal.
 When the water temperature setting input signal type is 4-20 mA
• External analog input signal of 4 mA: 0%
• External analog input signal of 20 mA: 100%
• External analog input signal of between 4 and 20 mA: the percent will be linearly interpolated.
