2
Serial communication abnormality, faulty setting (determined by the water heat exchanger unit, remote control
side)
Faulty remote control reception[E01]
• Detection method: No communication addressed to the device has been received for 3 minutes
Remote control transmission fault [E02]
• Detection method: The device cannot read it’s own transmissions for 3 minutes
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
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
Faulty transmission to the outdoor side from the water heat exchanger unit [E05]
• Detection method: The device cannot read it’s own transmissions for 3 minutes
Duplication of indoor unit address forbidden link cabling [E08]
• Detection method Another unit has the same indoor unit address as the unit
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
Faulty setting, setting not completed (determined by the water heat exchanger unit)
Faulty setting [L16]
• Detection method (setting temperature, chiller/water, shift) switch set outside specification range
Duplication of parallel address (when using RS485 communication) [L19]
• Detection method Another device has the same parallel address as the device
4
Other warnings (determined by the water heat exchanger unit)
Water heat exchanger unit freeze warning [P11]
• Detection method While the outdoor unit is operating, the freeze prevention temperature is detected by
either the freeze prevention sensor, the hot and cold water inlet/outlet sensor, or the refrigerant outlet
temperature sensor.
Interlock warning (ancillary equipment)[P23]
• Detection method Within 30 seconds after a hot and cold water pump operate command, the interlock
does not turn ON, or, the interlock turns off during a hot and cold water pump operate command.
Non-volatile memory (EEPROM) abnormality [F29]
• Detection method Inability to write normally
