13.8 Error codes

When a safety device is activated, an error code will be displayed on the user interface.
A list of all errors and corrective actions can be found in the table below.
Reset the safety by turning the unit OFF and back ON.
In case this procedure for resetting the safety is not successful, contact your local dealer.

FAILURE CAUSE
AND CORRECTIVE ACTION
1.Check the power supply cables should be conneted
stable,aviod phase loss.
2.Check whether the sequence of neutral wire and live wire are
connected reversely.
1. The T3 sensor connector is loosen. Reconnect it.
2.The T3 sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive
3. The T3 sensor failure, change a new sensor.
1. The T4 sensor connector is loosen. Reconnect it.
2.The T4 sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive
3. The T4 sensor failure, change a new sensor.
1. The Th sensor connector is loosen. Re connect it.
2.The Th sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive
3. The Th sensor failure, change a new sensor.
1. The Tp sensor connector is loosen. Re connect it.
2.The Tp sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive
3. The Tp sensor failure, change a new sensor.
1.wire doesn't connect between main control board PCB B and
main control board of indoor unit. connect the wire.
2. Whether there is a high magnetic field or high power
interfere, such as lifts, large power transformers, etc.. To add a
barrier to protect the unit or to move the unit to the other place.
1. Whether there is power connected to the PCB and driven
board. Check the inverter module PCB indicator light is on or
off. If Light is off, reconnect the power supply wire.
2.if light is on, check the wire connection between inverter
module PCB and main control board PCB, if the wire loosen or
broken, reconnect the wire or change a new wire.
3. Replace a new main PCB and driven board in turn.
