Gree air conditionerConnection of the external machine line:

1. The white wire is connected to No. 1 (compressor signal).

2. The black wire is connected to No. 2 (common end, neutral line, and the power supply line of the compressor controlled by the first line).

3. The red wire is connected to No. 3 (four-way valve.

signal line). 4. The brown wire is connected to No. 4 (the signal line of the outdoor fan electric motor, and the power supply of the outdoor fan motor is controlled by the No. 2 line).

5. The yellow and green two-color wire is connected to No. 5 (power grounding wire.

The role of the outdoor unit of the air conditioner:

The high-pressure and high-temperature gas discharged from the indoor unit is cooled and dissipated outdoors (through a fan) and condensed into the refrigerant.

The liquid is then sent through a capillary to the evaporator of the indoor unit.

The evaporation turns into a gas to absorb the heat in the room, and the temperature in the room gradually drops after repeated cycles.

Five taboos for the use of air conditioners:

1. Tightly closed doors and windows should not rely on air conditioning for a long time to rise and fall the temperature, and the windows should be disconnected for ventilation to maintain indoor air circulation and avoid lack of fresh air.

2. If ventilation equipment is not installed, a negative oxygen ionizer and a ventilator are installed at the same time as the air conditioner is installed, which can deliver a large amount of filtered fresh air to the air-conditioned room.

3. The temperature difference between indoor and outdoor is too large Don't adjust the indoor temperature too low in summer, and the temperature difference between indoor and outdoor should be 5 8.

4. The equipment is not clean The air conditioner and dehumidification device should be checked and cleaned regularly, especially the filter screen should be cleaned on time, so that it can really filter dust, germs and harmful gases.

5. During daily use, do not set the temperature too low, so as not to affect the service life of the air conditioner in high-speed operation for a long time. It is best to set it in automatic mode, which can not only cool down quickly, but also save electricity.

One is the compressor, one is the four-way valve, the other is the zero line, the zero line is determined first, and the other two are not connected to the right and then replaced.

The four wires of the outdoor unit of the Gree air conditioner, the thick two are for power supply, and the thin two are signal wires, which can only be connected together according to the same color.

1. The white wire is connected to No. 1 (compressor signal). 2. The black wire is connected to No. 2 (common end, neutral line, and the power supply line of the compressor controlled by the first line). 3. The red wire is connected to No. 3 (four-way valve signal line); 4. The brown wire is connected to No. 4 (the signal line of the outdoor fan electric motor, and the power supply of the outdoor fan motor is controlled by the No. 2 line). 5. The yellow and green two-color wire is connected to No. 5 (power grounding wire.

Question: There are 3 wires left in the air conditioning pipe.

There are no 5 wires.

The normal ones are five lines, and it is recommended to consult the after-sales service ** to avoid unnecessary trouble.

The wiring diagram is generally pasted on the cover of the electrical box of the internal machine, which is different for different models, and can be disassembled to view the machine.

When I ask you three, you always say five.

The line of the air conditioner is mainly composed of 4 wires and a signal line, and the signal line has a jack, as long as it is plugged in. The 4 wires are docked according to the color, generally marked on the binding post, as long as they correspond, if there is no marking, then the red live wire, the black zero line, and the yellow-green grounding.

Summary. Household air conditioners, outdoor unit wiring, generally live wire, neutral wire, ground wire! As long as the ground wire is connected correctly, it is done!

Five wires, three ports.

The yellow-green wire is the ground wire, which is connected to the iron shell of the air conditioner. The blue line is n, that is, the zero line is carried, and the common end connector of each chilu part of the external machine is the one with the most parallel wires. The brown line is L, that is, the live line, which is generally the control line of the compressor.

The remaining two wires are either red or yellow, one is connected to the four-way valve, and the other is connected to the Senfu external fan.
