Error Code [1302] (during operation)

1. Error code definition

High pressure fault 1 (Outdoor unit)

2. Error definition and error detection method

1) If the pressure of 3.78MPa [548psi] or higher is detected by the pressure sensor during operation (the first detection), the out-

door stops once, turns to antirestart mode for 3 minutes, and restarts after 3 minutes automatically.

2) If the pressure of 3.78MPa [548psi] or higher is detected by the pressure sensor again (the second detection) within 30 min-

utes after the first stop of the outdoor unit, the outdoor unit stops once, turns to anti-restart mode for 3 minutes, and restarts

after 3 minutes automatically.

3) If the pressure of 3.87MPa [561psi] or higher is detected by the pressure sensor (the third detection) within 30 minutes of the

second stop of the outdoor unit, the outdoor unit will make an error stop, and the error code "1302" will be displayed.

4) If the pressure of 3.78MPa [548psi] or higher is detected more than 30 minutes after the stop of the outdoor unit, the detection

is regarded as the first detection, and the operation described in step 1 above will start.

5) For 30 minutes after the stop of the outdoor unit, preliminary errors will be displayed on the LED display.

6) The outdoor unit makes an error stop immediately when not only the pressure sensor but also the pressure switch detects

3. Cause, check method and remedy

Cause

Check method and remedy

(1)

Indoor unit LEV actuation failure

Perform a heating operation and check the operation.

Cooling: LEV on the indoor unit

BC controller LEV1,3,

SVM1,1b,2,2b, SVA

Heating: LEV on the indoor unit

BC controller LEV3,

SVM2,2b, SV4a,SV4b,

SV4c,SV4d

Refer to the following page(s). [8-8 Troubleshooting

LEV Problems](page 322)

(2)

BC controller LEV malfunction

Heating only or heating main : Indoor LEV 3

Defrost : LEV3

(3)

BC controller SVM1 and 2 malfunction

→Cooling only or defrost

(4)

BC controller SVA and SVC malfunction

→Cooling only or cooling main

(5)

BC controller SVB malfunction →Heating only or heating main

Solenoid valve actuation failure (SV4a, SV4b, SV4c, or SV4d)

→Cooling only or cooling main

(6)

Port address setting error.

Confirm the port address of the indoor unit.

(7)

Refrigerant service valve actuation failure

Confirm that the refrigerant service valve is fully

(8)

Short cycle on the indoor unit side

Check the indoor units for problems and correct

them, if any.

(9)

Clogged filter on the indoor unit

(10) Reduced air flow due to dirty fan on the indoor unit fan
(11) Dirty heat exchanger of the indoor unit
(12)

Indoor fan (including fan parts) failure or motor failure

Items (7) through (12) above reduce the condensing capability of

the unit, resulting in high-pressure rise during heating operation.

(13) Short cycle on the outdoor unit

Check the outdoor units for problems and correct

them, if any.

(14) Dirty heat exchanger of the outdoor unit
(15)

Outdoor fan (including fan parts) failure, motor failure, or fan con-

troller malfunction

Items (13) through (15) above reduce the condensing capability of

the unit, resulting in high-pressure rise during cooling operation.

Check the fan on the outdoor unit.

Refer to the following page(s). [8-7 Troubleshooting

Outdoor Unit Fan Problems](page 321)

(16) Solenoid valve (SV1a) malfunction

The by-pass valve (SV1a) can not control rise in high pressure.

Refer to the following page(s). [8-6 Troubleshooting

Solenoid Valve Problems](page 315)

(17) Thermistor failure (TH3, TH7)

Refer to the following page(s). 3 [3-3 Functions of the

Major Components of Outdoor Unit(page 78)

(18) Pressure sensor failure

Refer to the following page(s). [8-5-1 Comparing the

High-Pressure Sensor Measurement and Gauge

Pressure](page 313)

(19) Failure of the thermistor input circuit and pressure sensor input

circuit on the controller board

Check the sensor temperature/pressure on the LED

monitor.

(20) Thermistor mounting problem (TH3, TH7)

Check the sensor temperature/pressure on the LED

monitor.

(21) Disconnected male connector on the pressure switch (63H1) or

disconnected wire
