Reset method [common for 1. to 3.]: After correcting the fault, allow for automatic recovery or press the
reset button.
1. Sensor faults (related to the water heat exchanger unit)
1) Faulty water heat exchanger refrigerant inlet temperature sensor (primary or secondary) [F01]
• Detection method: Open (-20ºCt) or short circuit (130ºC≤t)
2) Faulty water heat exchanger freeze prevention sensor (primary or secondary) [F02]
• Detection method: Open (-20ºCt) or short circuit (130ºC≤t)
3) Faulty water heat exchanger refrigerant outlet temperature sensor (primary or secondary) [F03]
• Detection method: Open (-20ºCt) or short circuit (130ºC≤t)
4) Faulty hot/cold water inlet temperature sensor [F10]
• Detection method: Open (-30ºCt) or short circuit (100ºC≤t)
5) Faulty hot/cold water outlet temperature sensor [F11]
• Detection method: Open (-30ºCt) or short circuit (100ºC≤t)
2. Serial communication faults or faulty settings (related to remote control of the water heat exchanger
unit)
1) Faulty remote control reception [E01]
• Detection method: There has been no communications addressed to the device for 3 minutes
2) Remote control transmission fault [E02]
• Detection method: The device cannot read it’s own transmissions for 3 minutes
3) Faulty reception from the remote control by the water heat exchanger unit [E03]
• Detection method: There has been no communications addressed to the device for 3 minutes
4) Faulty reception from the outdoor side by the water heat exchanger unit [E04]
• Detection method: There has been no communications addressed to the device for 3 minutes
5) Faulty transmission by the water heat exchanger unit to the outdoor unit [E05]
• Detection method: The device cannot read it’s own transmissions for 3 minutes
6) Duplication of indoor unit address [E08]
• Detection method: Another unit has the same indoor unit address as the device
7) Faulty transmission by the water heat exchanger unit to the remote control [E13]
• Detection method: The device cannot read it’s own transmissions for 3 minutes
3. Other warnings (determined by the water heat exchanger unit)
1) Water heat exchanger unit anti-icing warning [P11]
• Detection method: While the outdoor unit is operating, freezing temperature is detected by either
the anti-icing sensor, the hot/cold water inlet and outlet sensor, or the refrigerant
outlet temperature sensor.
2) Interlock warning (ancillary equipment) [P23]
• Detection method: Within 30 seconds after a hot/cold water pump start command, the interlock
does not turn ON, or the interlock turns OFF during a hot/cold water pump
start command.
3) Non-volatile memory (EEPROM) fault [F29]
• Detection method: Inability to write normally
