Does Hisense inverter universal version still need EE?

In this regard, he is a single model, so there is no way to use it universally in this regard, and it is necessary to find a target for him.

The normal ones will be there, unless they are not genuine. >>>More

Compressor starting capacitance, whether the capacity is appropriate, whether the wiring is loose, or fails. >>>More

Hisense inverter air conditioner in sleep mode, the temperature change of air conditioning is relatively slow,It is recommended to turn off the sleep mode first,Turn on the sleep mode when the indoor temperature reaches the required temperature。 >>>More

There are several reasons for the sound problem you said First, the indoor unit is not balanced First, there is something in the fan that causes the fan to be rubbed and hung The fan is not installed and fastened and so on Second, the installation of the air outlet grid is unstable, and when the grid swings back and forth (one side should be looser and the other side should be tighter), there will be a big and a small sound Third, the voltage of the inverter is unstable, the work is unstable, and the inverter emits electromagnetic sound If the sound from the outdoor unit is the sound of the outdoor unit First, the voltage of the inverter is unstable or the inverter itself is a problem that causes the output frequency to be large and small, the compressor will act at a high frequency and a low frequency, resulting in a large and small sound (and at the same time, the pipeline installation is not very fixed, the compressor itself is not very balanced, the screws are not tightened, or the impurities contain deeper this situation) This may be the main reason Second, that is, the outdoor unit is not installed and balanced, the possibility is not very large, but it is also necessary to pay attention to the solution, the order is as follows First, in the case that you determine that the internal machine is unbalanced, adjust the balance The balance adjustment of the external machine is not recommended for you to operate, It's very dangerous (under normal circumstances) Second, unplug the other loads on the air conditioning line (TV or something, etc.), and then change it to other sockets to check (this is mainly to check whether the power supply voltage is stable, enough voltage, if your home lines are unstable, enough pressure will be old fire) For the rest, you can only find the seller to repair or replace the product (this is limited to your non-professional operation) The outdoor unit you said stopped before the set temperature First, some of the set temperature has reached the set value temperature range, Generally up and down one or two degrees, etc., it may stop when it reaches 24 degrees, this general manufacturer set up (in the room temperature to keep the compressor in the range of 24 to 26 degrees, the compressor will not work, otherwise your air conditioner will be frequently turned on and shut down, this is normal, I said the temperature of 24 to 26 degrees is based on what you said 25 degrees), if you are not satisfied, this can be adjusted through the display operation interface, it is recommended not to pay attention. Second, the controller can't accurately output the control signal (the probability of the situation you said is very small) Okay, this is within the scope of my knowledge to explain to you, you can't avoid loopholes, I hope it will help you, if you are satisfied.
