1. Due to the negligence of the installer, the control power supply of the outdoor fan of the air conditioner may not be controlled by the host at all.

2. The air conditioner installer can connect the power supply of the outdoor fan to the air switch. As long as you turn on the air switch, the outdoor fan of the air conditioner will keep turning, and the outdoor fan will keep turning whether you turn on or off the main air conditioner.

3. The solution is to connect the main power supply of the outdoor fan of the air conditioner to the air conditioner control power supply (that is, the output point of the same contactor as the compressor). When the compressor is started, the outdoor fan will start running. On the contrary, when the compressor stops, the outdoor fan stops rotating.

Because this air conditioner is powered by three-phase power supply, the fan of the outdoor unit of the air conditioner cannot be connected reversely. If the power cord is connected backwards, the fan will reverse, which will affect the refrigeration effect of the whole machine.

Your machine is newly installed, so you can ask the supplier to reconnect the electricity correctly to avoid unnecessary losses such as electricity charges.
