1. Error
Code
Return air temperature sensor (TH21) fault (Indoor unit)
Return air temperature sensor (TH4) fault (OA processing unit)
Pipe temperature sensor (TH22) fault (Indoor unit)
Pipe temperature sensor (TH2) fault (OA processing unit)
Reverse connected inlet/outlet pipe (indoor unit)
Gas-side pipe temperature sensor (TH23) fault (Indoor unit)
Gas-side pipe temperature sensor (TH3) fault (OA processing unit)
Intake air temperature sensor (TH1) fault (OA processing unit)
Intake air temperature sensor (TH24) fault (All-fresh (100% outdoor air) type indoor unit)
2. Error definition and error detection method
If a short or an open is detected during thermostat ON, the outdoor unit turns to anti-restart mode for 3 minutes. When the
error is not restored after 3 minutes (if restored, the outdoor unit runs normally), the outdoor unit makes an error stop.
Short: detectable at 90°C [194°F] or higher
Open: detectable at -40°C [-40°F] or lower
Sensor error at gas-side cannot be detected under the following conditions.
During heating operation
During cooling operation for 3 minutes after the compressor turns on.

Cause
Check method and remedy
(1)
Thermistor failure
Check the thermistor resistor.
0°C [32°F]: 15 kohm
10°C [50°F]: 9.7 kohm
20°C [68°F] : 6.4 kohm
30°C [86°F] : 4.3 kohm
40°C [104°F] : 3.1 kohm
(2)
Connector contact failure
(3)
Disconnected wire or partial disconnected
thermistor wire
(4)
Unattached thermistor or contact failure
(5)
Indoor board (detection circuit) failure
Check the connector contact.
When no fault is found, the indoor board is a failure.
