Setting The Water Temperature Using Analog Signal Input; Select The Analog Input Format - Mitsubishi Electric QAHV-N560YA-HPB Installation & Operation Manual

Setting the water temperature using analog signal input

Select the analog input format

• When the water temperature setting input signal type is set to 0 (4-20 mA)
• External analog input signal of between 5.9 and 18.3 mA: the preset temperature will be linearly interpolated.
temp B 90ºC
temp A 40ºC
• When the water temperature setting input signal type is set to 1 (0-10 V)
• External analog input signal of between 1.0 and 9.1 V: the preset temperature will be linearly interpolated.
temp B 90ºC
temp A 40ºC
• When the water temperature setting input signal type is set to 2 (1-5 V)
• External analog input signal of between 1.5 and 4.5 V: the preset temperature will be linearly interpolated.
temp B 90ºC
temp A 40ºC
• When the water temperature setting input signal type is set to 3 (2-10 V)
• External analog input signal of between 2.9 and 9.1 V: the preset temperature will be linearly interpolated.
temp B 90ºC
temp A 40ºC
5.9 mA 18.3 mA Input current
1.0 V 9.1 V Input voltage
1.5 V 4.5 V Input voltage
2.9 V 9.1 V Input voltage
Preset temperature = (B - A) * (Input current - 5.9 mA) / 12.4 mA + A
Change of 0.12 mA or less is not recognized.
Preset temperature = (B - A) * (Input voltage - 1.0 V) / 8.1 V + A
Change of 59 mV or less is not recognized.
Preset temperature = (B - A) * (Input voltage - 1.5 V) / 3.0 V + A
Change of 29 mV or less is not recognized.
Preset temperature = (B - A) * (Input voltage - 2.9 V) / 6.2 V + A
Change of 59 mV or less is not recognized.
