It is a very nice tutorial, Sir Bon...I've learned another trouble and how to rectify it..thanks..

Hi ,this video is just in time, I will have to change the main board to Daikin. Thanks

[@BonMj]

This is vrv4- A , auto charge system.

[@deshanabeysekara5124]

your videos big help for us.Thank you sir...

[@BonMj]

Thanks

[@Tirumalaaircontrols]

Could you please let me know the details about that copper line connected to pcb

[@ismaielchaudhary]

Sir what would be reason Daikin VRV liquid line is freezing, I check solenoid and sensors and ohms reading look acceptable.

Great jo brother 👍

Hi Mr Bon, i love watching your instructional videos i just wondered how would you charge the extra refrigerant, if you could not determine the pipe length, does the auto charge procedure automatically detect the correct refrigerant charge ?

[@jiezhang730]

Hi, May I ask for Daikin R407c, ds2 and ds3 which button should be on?

[@NOVAAIRCONDITIONINGNOVAAIRCOND]

mr bon juat wanna ask when i want to do auto charge should i open valve to release gas from compressor first or dont open the valve and auto charge it and then release the gas from compressor ?

[@CircinusMusic]

Sir if panel fault no need gas recharge? Just to observe the to1 to po9 only?

[@BonMj]

After reset if U3 , u need to do .

[@Marcelo.M.Quaiotti.01]

Hi. Do you have U3-10 in the manual?

[@BonMj]

Correction.
The model is RXQ16AYM.
Thanks

[@pappykwabee5296]

I have worked on the vrv 2 and 3 a lot but I have not worked on vrv 4 yet.Please why do you have to do all these settings(auto charge and test run) after you have replaced the main Pcb.On vrv 2 and 3
Is straight forward you don't need to do anything.
What is auto-charge by the way?Is it something to do with the refrigerant being recharged into the system?
PLEASE advise.thank you

[@BonMj]

VRV 4 auto charge system, when you replace the main pcb, this procedure is compoundsery. by manufacturer.

[@BonMj]

Check incoming first

[@joycetan4180]

Hi I got the same model and it show f6 error on the peu controller. Can advise please? Thanks I advance

[@BonMj]

May system overcharge
Or check liquid pipe thermistor

[@Lee-mu2jc]

老板谢谢你每次用心讲解
如果是换其他电板也是一样要这样做吗
也是vrv4 还是只是换你这样的电板才需要这样做 谢谢

[@BonMj]

VRV4 有两个款
1)有Auto charge
2)没有Auto charge
这个video 是 vrv4 有auto charge,所以要这样做。
如果没有auto charge, 只需要test run 就好。

[@Lee-mu2jc]

@@BonMj 老板要怎样分辨哪一个款式是有没有auto charge谢谢

[@BonMj]

@@Lee-mu2jc你注意看service valve那边(check gas 的地方右手边)，有个进gas 的service port.
你注意看我video,蓝色pipe就绑在那个service port.

[@choonhaukwa1878]

请问Auto charge 出现 P9 过后，是不是就说明gas已经足够，不用再进了？

[@BonMj]

其实auto charge 最多可以进4kg.
如果新装的VRV要先算pipe的长度，在auto charge之前要先进gas，然后再auto charge.
如果像这个video,只是换电板，程序上一定要做auto charge,但是过程是很快的，应为gas是足够的。
对，P9是完成了auto charge.

[@Ramprasad-fo5ui]

So great video

[@syaha-dw9pj]

Hi Mr Bon, if a model RXQ14TY1 VRV4 after replace the main pcb are we can test run without auto charge first?

[@BonMj]

Depend by error, if no error no need

[@traduccion1024]

What happens when the three displays are fixed but do not turn off?

[@BonMj]

Comunication problem

[@SasiKumar-gj3jg]

What is the reason for E2 error in Daikin vrv4 outdoor unit and how to rectify?and also three times second inverter compressor changed but again second inverter compressor grounded

[@BonMj]

E2 you need to check the high pressure switch and high pressure sensor reading.
Compressor replace 3 times!suggest you release all the gas,make the pipe calculation ,and recharge gas with correct quantity.

[@CHOPPA78]

Release means reclaim in to a reclaim cylinder , don't want to release" could be misunderstood !

[@alanwang2900]

Great video, by the way, when auto charge active, is this gonna cause the system over charged?

[@BonMj]

When new air con is done,u can gauge the amount of refrigerant needed to be charged by measuring the pipe lenght and pipe size.
Auto charge can only charge 4kg of refrigerant.

[@BonMj]

For this case the the auto charge just run for awile and stop.just a bit charge in only

[@CHOPPA78]

Hi Mr Bon, i love watching your instructional videos i just wondered how would you charge the extra refrigerant, if you could not determine the pipe length, does the auto charge procedure automatically detect the correct refrigerant charge ?

What was the error meaning and wht did we get the error
Just reset it and pretend nothing is wrong?

[@BonMj]

U3-Test run execution failure.
This error appear when we do the test run after replace new pcb.
Try it twice is same error U3.
Use the new installation method, Auto charge and after that test run.
The unit but to normal.
