The cassette fan coil has an ABS panel. The surface of the ordinary fan coil is only galvanized. The main advantages of the cassette are beautiful appearance, including sound-absorbing sponge, low noise, and no other accessories, such as air outlets, Metal hoses and the like. Like ordinary fan coil, card fan coil is used in conjunction with chillers to provide cooling or heat to the room. Card fan coil belongs to exposed fan coil, but it can be embedded in the ceiling, so it does not occupy space and is beautiful and elegant.

What is the reason for the small air volume of the cassette fan coil:.
The cassette fan coil is also called ceiling fan coil. During installation, attention must be paid to fixing the stable line smoothly.
1. Check whether the motor capacitor is damaged and whether the line is connected incorrectly.
2. Determine whether the capacitor specification is appropriate, and replace the large capacitor when necessary (for example, 1μF is replaced by 1.5 μF and 1.5μF is replaced by 2μF).
3. Determine whether the wiring of the third power cord of the motor is correct and whether the fan coil has changed.

Card fan coil common can not start 7 reasons, as follows:
1. The power supply is not sent. Confirm that the power supply has been sent.
2. External circuit disconnection confirms that the power supply and control circuits are intact.
3. Electrical wiring errors are checked according to the instructions on the wiring nameplate.
4. The line metal connector is not in good contact with the metal pressure plate of the wiring base to rewire.
5. Loosen the wiring plug of the motor on the wiring base and insert the plug according to the instructions of the wiring nameplate.
6. Contact the after-sales department with the open circuit of the motor lead wire, and it is not allowed to disassemble and inspect the motor without authorization.
7. The motor capacitor wiring of the cassette fan coil is open or the capacitor is damaged and the internal winding of the motor is open.

In the hot summer, the central air conditioner is like a "life-saving straw". Without it, you can imagine what kind of scene it is. There is a component in the air conditioner that is very important. Under the control of the thermostat, it can make the working state of the air conditioner change accordingly. This component is the electric valve of the cassette fan coil, which can flexibly control the internal temperature. It can be seen that when it has problems, The air conditioner can't work normally, therefore, attention should also be paid to maintenance at ordinary times. It is suggested that everyone should proceed from the following three aspects:
1, installation:
From the installation point of view, when this component is installed at a specific position inside the air conditioner, it should check its sealing condition and deal with any problems in time. This is related to the electric valve and whether the whole air conditioner can operate. After that, it should also check whether the screws are loose. If there is, it should be screwed again immediately. Otherwise, the card fan coil electric valve will not only strike, but also cause more harm, let the personal safety of the air conditioning owner face great risk.
2, the working environment:

From the perspective of working environment, it must be ensured that the position of the electric valve of the cassette fan coil unit is dry enough, ventilated enough and clean enough. If the electric valve of the cassette fan coil unit is in a very bad environment, it is humid and hot, and the fan coil unit will be easily affected, thus its components will be gradually worn out. Therefore, it must be ensured that the environment meets the above standards during installation, and usually also pay special attention to maintain this environment, in addition, even if the installation of the environment is up to the standard, but also should always pay attention to clean, found that dirt needs to be dealt with in a timely manner.
3, daily inspection:

From the perspective of daily inspection, regular inspection must be carried out. After the electric valve of the cassette fan coil works for a period of time, various problems may occur. If it is not found, it will become more serious. Therefore, regular inspection is essential. During the inspection, in addition to confirming whether the environment is up to standard, it is also necessary to confirm whether the sealing surface is damaged and other parts are in good condition. If the sealing surface is damaged, then the electric valve can not be well sealed, if other parts are damaged, such as the drive work slack, or strike, then it must be replaced with new parts, so as to avoid the electric valve can not work properly.
