EU - The problem. Run on time, delay start.

E6 - Fault. Internal / external, - control board malfunction (signal receiver does not work).

When checking is closed,

E7 - Incorrect signal generation (incorrect connection, break, short circuit).

E8 control board malfunction (signal receiver does not work).

E9 - wrong connection, break, short circuit.

E0 - Errors in the split system control (signal receiver does not work). Check the remote control unit

E3 - Errors in controlling the split system (error transmission)

E4 - Errors in controlling the split system, - the signal receiver does not work.

E5 - Undervoltage in the network.

EF - M-NET specification, - transmission errors. Check the unit indoors and outdoors.

Ed - Serial transmission errors. Check the temperature and pressure sensors ...

P1 - The thermo sensor does not work, check the resistance of 10 OM (TH1).

P2 - The temperature sensor has overheated, check the system (Th2).

P4 - Condensate drain drained, the liquid level sensor (DS)

P5 - Condensate drain pump does not work. Verification closed, defective

P6 - Freeze / overheating protection, check system pressure.

P8 - Check evaporator temperature. When testing, the sensor is closed.

P9 - Temperature thermistors / condenser / evaporator (TH5)

F1 - Check the phase sequence for the three-phase Huke air conditioners.

F2 - L3 there is no phase.

F3 - 63L connector, no signal, an open.

F4 - 49C connector, see the connection diagram - there is no signal, an open.

F9 - Connector 2 or more no signal, an open.

FA - L2 - phased phase failure, intermittent phase or 51cm connector no signal, breakage.

F7 - Re-phasing is necessary, the compressor is turning in the opposite direction.

F8 - No contact in interconnection.

U2 - Abnormal high return temperatures, check the gas pressure in the system and measure the current overload, possible shutdown of the compressor by current.

U2 - Internal thermostat the error code (49C) does not work.

U1 - Abnormally high pressure (high pressure sensor 63H triggered)

U1 - Gas leakage, the sensor has triggered the minimum gas pressure in the system.

UE - High pressure, overheating (ball valve closed)

UL - Add freon, low pressure.

Ud - The thermal protection of the air conditioning compressor has tripped.

U6 - Malfunction of the compressor Huke (overload) winding in the breakage.

UA - Malfunction of the compressor (Huke thermal protective relay has tripped).

UF - Compressor malfunction (start blocked) winding in the cliff.

UF - Malfunction of Huke air conditioner. Malfunction of the compressor (working blocked) winding in the cliff.

UH - Current sensor error. The voltage in the network has disappeared briefly, the default failure

U3 - Closure of the temperature sensor / sensor is dirty, or leakage is impaired.

U4 - Open the humidity sensor / check terminal contacts, replace the sensor.

Display on the remote control

E0 - Diagnosis of the failure of receiving / transmitting an error signal. When checking is closed,

P1 - Diagnosis of air intake sensor malfunction, sensor is broken. When testing is closed, change the sensor.

P2 - Troubleshooting of pipes, the sensor is broken. When checked, closed, replace the part.

P4 - Diagnosis of sensor failure Drain (humidity) sensor is broken. When checking the sensor is closed.

P5 - Fault diagnosis - gas leakage, protection has tripped. In the test is closed.

P6 - Fault diagnosis, - freezing of the indoor unit of the split system / the overheat protection in the cooling mode has tripped. At check is closed.

P3 - Diagnostics, - inter-unit connection check (signal transmission / reception). At check is closed.

P7 - System error (wrong address) Verification is closed. See email. Scheme of connections.

P8 - Check the temperature and pressure sensors ...

LD1 - compressor failure. LED phase sequence flash, check phasing.

LD2 - Heating does not work. The LED blinks. There is no signal on the three-way valve, valve malfunction.

LD3 - 63H1 Temperature sensors, check resistance.
