Wouldn't mind shadowing you for a few weeks with fault finding on different systems 👍👍
Thanks
great teacher nobody like him for me

Welcome
Hi ,this video is just in time, I will have to change the main board to Daikin. Thanks
This is vrv4- A , auto charge system.
-I'm Myanmar Citizen.
-I want to work and learn from you.
-I'm in Singapore now!
It is a very nice tutorial, Sir Bon...I've learned another trouble and how to rectify it..thanks..
Thanks
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 ?
Could you please let me know the details about that copper line connected to pcb
your videos big help for us.Thank you sir...
Thanks
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 ?
Thank You
You're welcome
Sir what would be reason Daikin VRV liquid line is freezing, I check solenoid and sensors and ohms reading look acceptable.
❤️❤️
Thanks
exelente pagina muchas gracias
Welcome

Thanks
Why need to do freon charging when replacing the PCB?
As always
Great jo brother 👍
Thanks bro
Hi, May I ask for Daikin R407c, ds2 and ds3 which button should be on?

Thanks
Hi sir please tell me 99 settings video
Hi. Do you have U3-10 in the manual?
Superb sir.
Thanks
So great video
Thanks
Thank you Mr Bon to share you knowledge
Thank you sir❤❤
Welcome
Do u conduct any course for water cooled package / air cooled package unit?
Thank you sir
Welcome
Great 👍sir
Thanks
Great video, by the way, when auto charge active, is this gonna cause the system over charged?
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.
For this case the the auto charge just run for awile and stop.just a bit charge in only
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 ?
MERCI GREAT JOB
Thanks
Sir if panel fault no need gas recharge? Just to observe the to1 to po9 only?
After reset if U3 , u need to do .
Thanks a lot
Welcome.
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
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。
@@BonMj 老板要怎样分辨哪一个款式是有没有auto charge谢谢
@@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.
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
VRV 4 auto charge system, when you replace the main pcb, this procedure is compoundsery. by manufacturer.
Halo Mr.bon,untukVRV A apabila ada additional indoor perlu melakukan prosedur Auto charge juga ?
Ya...
Hello nice Job bro 🇹🇷👍🛠️
Thanks bro
Hi I got the same model and it show f6 error on the peu controller. Can advise please? Thanks I advance

@BonMj OK sir thanks
What was the error meaning and wht did we get the error
Just reset it and pretend nothing is wrong?
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.
Explain sir Aircon bypass settings
Thanks
Bagus ah you...
Terima kasih master
Hi Mr Bon, if a model RXQ14TY1 VRV4 after replace the main pcb are we can test run without auto charge first?
Depend by error, if no error no need
Hi mr.bon please help we was replacing the main pcb.after that ua is appear please help.what the next step
PCB setting correct?
Yes mr. Bon with thanks
Thank you very much sir, What about error code LC - 14 . AND F6 -02

@@BonMj thank you very much.
Hi mr bon, i have to change both the INV1 pcb and the CU pcb but the problem Still exist, do you have an idea plz
What happens when the three displays are fixed but do not turn off?
Comunication problem
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？
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.
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
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.
Release means reclaim in to a reclaim cylinder , don't want to release" could be misunderstood !
super nice 👌👌👌
Thanks
