6. Hot water temperature sensor error display
1) Hot water temperature sensor open/short circuit
- Only H1 on the FND flashes.
- The heater output is turned off.
2) When the hot water temperature sensor is in normal operation, the FND and the heater operate
according to the hot water temperature.
7. Overheated water sensing
1) When the hot water temperature is 98°C (14.323kΩ) or higher, the water is deemed overheated
and the following measure is taken.
- The heater output is turned off.
2) When the hot water temperature is 88°C (19.833kΩ) or lower, the overheating status is cancelled.
The heater operates according to the hot water temperature.
8. Compressor and heater operation control with intervals
1) When the compressor and heater operate at the same time, there will be at least 1-second
interval between them.
9. When there is a water level sensor error or overflow, the heater is turned off.
Cold water control (compressor control)
1. When the cold water selection switch is on, the compressor is controlled according to the current cold
water temperature.
1) Compressor-on temperature: 7.3°C (114.042kΩ) or higher
2) Compressor-off temperature: 17 minutes after sensing 4.5°C (130.351kΩ) for 1 second
(only when the temperature is 6°C or lower)
2. Cold water selection switch on
1) When the cold water selection switch is pressed, the function is selected.
2) When the cold water selection switch is on, the compressor output is controlled according to the
cold water temperature. Re-operation starts 5 minutes later.
3) FND display status: Cold water LED segment (C1) is turned on together with the LED that
corresponds to the current cold water temperature (C2, C3, C4, C5).
3. Cold water selection switch Off
1) When the cold water selection is On, pressing the cold water selection switch for 2 seconds or
more turns off the cold water function.
2) FND display status: All the COLD LED segments (C1/C2/C3/C4/C5) are turned off.
4. FND display control specifications according to the cold water temperature
1) C2/C3/C4/C5 is turned on according to the cold water temperature.
2) The On/Off control specifications according to the colt water segment are as the following:
COLD segment ON OFF Remark
C5 4.5°C (130.351kΩ) 6°C (121.291kΩ)
C4 7°C (115.647kΩ) 9°C (105.224kΩ)
C3 10°C (100.412kΩ) 13°C (87.392kΩ)
C2 14°C (83.48kΩ) 17°C (72.866kΩ)
C1 - -
Cold water selection switch is on
→ It is On all the time.
