2: The stepping motor output socket (SWING-MOTOR) is a 6-pin socket with the common side (12V) on both sides. When connecting, the common end of the wind direction motor plug must be inserted into a common end of the stepper motor output socket; if the motor rotates in the opposite direction, the common end of the wind direction motor plug should be inserted into the other common end of the stepper motor output socket.

Air conditioning computer board winter use precautions:

Recently, some users have reported that air-conditioning computer boards have encountered problems during installation and use in winter, causing a lot of trouble. In fact, as long as we understand the principle of air conditioning heating a little, we can avoid these problems, not because of the quality problems of the control panel, please use the user with confidence.

Let me give you an example of the main problems of the user:

The main heating does not defrosting or defrosting occurs frequently, and the machine does not work when heating. First of all, we need to know the working principle of air conditioning heating. In winter, the air conditioning is internal mechanism heat, and the external machine is going to be cooled. Because the outdoor temperature is cold in the winter and the moisture in the air will be in the condenser of the air conditioner. On the thin ice (referred to as frost), the heat conversion rate is reduced, the internal heat is reduced, this time it needs to be defrosted, the defrosting is to make the air conditioner in the cooling state (internal cooling, external mechanism heat), but The internal machine does not blow, and the external machine can melt and remove the frost due to heating, and then switch to the heating state again. Therefore, when using air conditioners in winter, the working state of the air conditioner is heating, and the two processes of defrosting work alternately. How does the air conditioner decide when to defrosting The original air conditioner is equipped with a temperature sensor on the outdoor condenser. When the temperature of the temperature sensor is below zero, the defrosting work is carried out. Above zero, it is not. Work, this is the principle of defrosting of the original air conditioner.

The principle of defrosting of Junda air-conditioning computer board:

Since the modified air-conditioning computer board does not have the outdoor sensor function, because the outdoor sensor has no way to install or install it, the general modified air-conditioning computer board does not have this function. Our air-conditioning computer board uses the timing defrosting and the tube temperature sensor. Intelligent cream two ways to solve the problem of defrosting.

The first type: timing defrosting is for the single sensor of the group (such as QD-U02C, U02B, etc.), the controller will continue to work for 40-60 minutes, and a defrosting operation will be performed. The defrosting time is 5-7. Minutes, when the defrosting, the internal machine stops working, the defrosting ends, and the heating work continues. This defrosting method is to temper a frost at a certain time, no need to defrose.

The second type: tube temperature intelligent cream is for products with tube temperature sensor (such as QD-U03A+, QD-U05G+, etc.), because there is no outdoor sensor, it is determined according to the tube temperature test temperature, every 25-30 Test the tube temperature in minutes. When the tube temperature is lower than 36-38 degrees, the air blown out by the air conditioner will not be hot. It is considered that the outer machine is frosted and needs to be defrost. The air conditioner will perform defrosting work. If it is higher than 36- At 38 degrees, it is considered that the air conditioning heating effect is ok, and no defrosting is required (even if there is frost on the outside machine). This defrosting effect has a lot to do with installation. The installation is very good, the installation is not good will lead to two results, the defrosting is too frequent or not defrosting for a long time, the reason is that different manufacturers will set the position of the tube temperature sensor different, some are excluded The gas port is farther away, the temperature of the heating pipe is relatively lower, and some are closer to the exhaust port, and the temperature of the heating pipe is relatively higher. In order to achieve a good defrosting effect, we need to adjust our tube temperature installation position during installation, not necessarily in the original air conditioning tube temperature installation position. After the installation is complete, we must observe the air conditioning situation. If it is found that the temperature is not defrosted for a long time, it means that the temperature of the original tube temperature is a bit high, and the tube temperature sensor should be moved away from the exhaust port appropriately. Move to a place where the tube temperature is relatively low) and observe the defrosting effect. If the defrosting is found to be too frequent, it means that the temperature of the original tube temperature is a bit low. The tube temperature sensor should be moved closer to the exhaust port (that is, move to a place where the tube temperature is relatively high). Defrost effect. Finally, it is emphasized that the sensor and the condenser should be in close contact regardless of how the tube temperature sensor is installed.

Here are some solutions to the problem of using air-conditioning computer boards in winter.

Question 1: The air conditioner has stopped working for a few minutes, and it takes a long time to start.

Answer: This is the air conditioning in the defrosting work, the internal machine all stopped, I feel the air conditioning is down, in fact, it is defrosting work, it takes 5-7 minutes, so some users can not wait for this time, it is said that the air conditioning is not normal, please Wait patiently, not so long for dozens of minutes.

Question 2: The air conditioner has stopped working for a few minutes. Has not started.

Answer: When the indoor temperature sensor is installed, the condensation fins in the room are too close or in contact. Please install the room temperature sensor away from the condensation fins. It can be installed outside the air inlet. It is recommended to install it. Air conditioning side, but do not seal inside the air conditioner, try to expose the air conditioner outside.

Question 3: The air conditioner does not defrost for a long time.

Answer: The temperature of the original tube temperature is relatively high. Please refer to the second method of the group defrosting method to adjust the tube temperature sensor to a point where the tube temperature is low.

Question 4: Air conditioning defrosting is frequent and the interval is too short.

Answer: The temperature of the original tube temperature is relatively low. Please refer to the second method of the group defrosting method to adjust the tube temperature sensor to a place where the tube temperature is high.

Question 5: The air conditioning is not clean.

Answer: Our product defrosting time is fixed. It is 5-7 minutes per defrosting. It may not be clean when it is cold below 5 degrees, because there is no outdoor sensor. Only use QD-U12A products with outdoor sensors, or use QD-U03C+, QD-U05PGC products with independent control of outdoor fans, the defrosting effect will be much better.

Question 6: There is no frost on the outside of the air conditioner, but the air conditioner will also defrosting.

Answer: If a single sensor product is a timed defrosting, this may be the case. If it is a dual sensor product, please refer to the second method of the group defrosting method to adjust.
