temperature
fine control
function
(hardware)
• C/T UP function
- The C/T UP jumper is cut to increase the control temperature 0.5 °C (
≒
3.0 kΩ).
COOL Segment ON OFF
C3 6.2 °C (120.138 kΩ) 8.3 °C (108.747 kΩ)
C2 9.5 °C (102.786 kΩ) 12.0 °C (91.509 kΩ)
C1 Always ON
- Temperature detection resistance range: 160.0 kΩ ~ 12 kΩ
• C/T DOWN function
- The C/T DOWN jumper is cut to decrease the control temperature 0.5 °C
(
≒
3.0 kΩ).
COOL Segment ON OFF
C3 5.7 °C (123.045 kΩ) 7.8 °C (111.344 kΩ)
C2 9.0 °C (105.224 kΩ) 11.5 °C (93.649 kΩ)
C1 Always ON

The above data may vary depending on the method of calculation with figures by
simple computation.
- Temperature detection resistance range: 163 kΩ ~ 13 kΩ

Other
• Cold water temperature thermistor model: MLT-50B
• Thermistor temperature detection error range: ± 0.5 °C or less
• The cold water temperature sensing circuit's partial pressure resistance is D grade
(0.5 %).
• The cold water temperature is checked 100 times and, if it is within a set range at
those 100 times, the temperature is detected as normal.
• Cold water temperature detection range: 0 °C ~ 55 °C (
≒
163 kΩ ~ 15 kΩ)
