COOL control function (compressor control)
Function Explanation
1.
Compressor
control
function
• If the COOL selection switch is ON, the compressor is controlled according to
water level and cold water temperature.
- Compressor ON temperature: 7.8 °C (111.344 kΩ)
- Compressor OFF temperature: 5.7 °C (123.045 kΩ) + 20 minutes delayed
operation (when 30 °C or more)
- After 1 minute of compressor operation, cold water temperature sensor detects
and then a delay time is decided.
- It is set at 20 minutes for 30 °C or more; 9 minutes for between 15 °C and 30 °C;
and 0 minutes for 15 °C or less.
- If the temperature sensor detects 5.7 °C, the compressor stops after 20 minutes'
delayed operation regardless of changes in temperature. If the temperature
becomes 7.8 °C (compressor ON temperature) or more, the 20 minutes' delayed
operation is canceled.
• COOL selection switch ON
- The COOL function is selected if the COOL selection switch is pressed briefly
(200 ms or more).
- Compressor output is controlled according to water level and cold water
temperature after the COOL selection switch is ON for 5 minutes.
- The compressor only operates if low water level is detected. The compressor
does not operate if there is a water level sensor error or low water level is not
detected.
- FND display status
→ C1 kept always ON
→ C2/C3 controlled ON/OFF according to cold water temperature
• COOL selection switch OFF
- The COOL function is turned off if the COOL selection switch is pressed and
held (1s or more).
- Compressor output is turned OFF after the COOL selection switch is OFF for
1 second.
