• When the water temperature setting input signal type is set to 2 (1-5 V)
• External analog input signal of 1.5 V: 0%
• External analog input signal of 4.5 V: 100%
• External analog input signal of between 1.5 and 4.5 V: the percent will be linearly interpolated.
• When the water temperature setting input signal type is set to 3 (2-10 V)
• External analog input signal of 2.9 V: 0%
• External analog input signal of 9.1 V: 100%
• External analog input signal of between 2.9 and 9.1 V: the percent will be linearly interpolated.
100%
0%
1.5 V Input voltage 4.5 V
Load ratio
*%
Preset temperature = 100% * (Input voltage - 1.5) / 3.0 V
Change of 29 mV or less is not recognized.
100%
0%
2.9 V Input voltage 9.1 V
Load ratio
*%
Preset temperature = 100% * (Input voltage - 2.9 V) / 6.2 V
Change of 59 mV or less is not recognized.
*%: 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.
