    Hi to all.
    I need service manual for new VRV 4.
    The DK tech line is not relevant enough (for the moment) to give us informations...!
    But next i will try to start one RXYQ10T7Y1B by myself...
    Once a service man tried to launch TEST and on step 10 on the new display (?) the system failed to U3.
    He tried again and then after it failed to U3-P2.
    I think it's a matter of auto charge or something like that...maybe i could disable?
    He has calculate the amount of refrigerant like III series upon the lengh and weigh of the liquid lines and he charged the amount.
    I will go there with the latest version of vrv checker software (1.53a) but i need advise to lead commissioning as well.
    Hope i'll find (nice) RE member to help me ?
    Thanks

    Re: New Daikin VRV 4 service manual

    10 point of test start - a unit stop.
    U3 in this case - the unit is efficient, but function of automatic search of leak which joins in a mode 2-88 isn't included, and by default not activated.
    Cheker won't help, there now new software and a new box for 400 euros.

    Re: New Daikin VRV 4 service manual

    As you remember to vrv3 and others it was possible to carry out test start having excluded check of amount of freon. Here too there is this function 2-88, it is initially active and it needs to be disconnected, (2-88 to put instead of 0 - 1) and then to refuel system with the help of software. Problem that the software meanwhile isn't available. And your second start the test of a mode showed an error of P2 - extraordinary low pressure in a gas station mode. Advise to open the gas valve)))

    that it is advisable to disconnect check of amount of freon

    Change of value of the control chosen in a mode 2:
    - Execute transition to a mode 2 (for this purpose press the button
    BS1 also hold it within not less than 5 seconds),
    then choose the necessary control. It becomes
    BS2 button pressing.
    - Receiving access to value of the chosen control
    it is carried out by single pressing of the BS3 button.
    - Now the BS2 button serves for a choice demanded
    values of the chosen control.
    - Having chosen demanded value, set change
    current value single pressing of the BS3 button.
    - That the system started working in compliance
    with the chosen value, press the BS3 button once again.

    p.s. I mixed a little, 2-86 control of system on leaks. As I understood periodically supervises freon volume in system.

    Ok i think i understand...
    Didn't know mode 2 setting 88 binary set 1 or 0 before, that's why i was confuse.
    I've had this kind of problem with the RQYQ series it was sometimes difficult to achieve the TEST...
    So i can disable the function and of course check the stop valves and run the service checker with the latest version. I think 1.53c instead of 1.53a.
    Many thanks (if i'm wrong please advise!)

    Re: New Daikin VRV 4 service manual

    Yes, everything is correct. Just in case steps which are passed in a test mode.
    Stages of automatic procedure of trial start:
    - "t01": control before start (alignment
    pressure)
    - "t02": control at cooling start
    - "t03": stable condition of cooling
    - "t04": connection test
    - "t05": check of locking valves
    - "t06": check of length of pipes
    - "t07": check of quantity of a coolant
    - "t08": if [2-88]=0, collecting detailed information
    about a coolant
    - "t09": coolant pumping
    - "t10": block stop

    Hello
    Here i'm back with my new VRV IV.
    During the Test the system failed to LC-14 fault as i understand it means pb of communication between main
    board and Inverter board.
    And on new series they are 2 INV pcb with 2 INV scroll comp i think from 14 to 20 Hp.
    I've check the whole wires and connectors, each Pcb has a green led flashing on it...
    Local DK tech service ask me to change the 3 pcb's !!!
    I think I REALLY NEED THE SERVICE MANUAL ON IT
    Awaiting to any suggest

    Re: New Daikin VRV 4 service manual

    Excuse dude but I have no service manual. Cheker connected to system? Tried to start without a test mode? What did it show on loading of 1 inverter and current?

    INV1 -A1P (X20A, X28A, X40A)
    Check here these connections, check wires.

    Hi i'm still with my new one!
    We've finaly change the inv pcb boards and lead the test run (run fine now)
    The new test can last from 3 to 4 hours (!) so...take time while you decide to push the button or disable this function.

    Yes it was with detection of leak first.
    Without this function it takes 35 to 55 mn
    I've got recording with short test cooling mode and heat also, if someone's interesting of, it's about 1 RXYQ10 and 1 RXYQ12T7Y1B

    Ps: sorry Rusbuka i don't have your chiller software as you asked by your PM

    Re: New Daikin VRV 4 service manual

    Hi Bratosin
    You'll need at least 1.53A software and even better with 1.53C
    To have a short TEST you will read above that Rusbuka helped me by changing the setting 88 in mode 2.
    My opinion is you can start with the short test and after you have to launch the long test (be careful i don't speak about auto-charge!!!).
    But if you do that you have to calculate the amount of refrigerant depending on the lengh, size, and combination of indoor, and then charge by the service port (the same as for auto-charge) using the setting 20 in mode 2.

    Re: New Daikin VRV 4 service manual

    Actually never used autocharge function as conditions for this opertion practically weren't. Main thing pumping and filling of evaporators, and working parameters. Only through a cheсker)

    p.s. WOW sow interesting logs, many thx )))

    Re: New Daikin VRV 4 service manual

    Hi everyone,

    I am on the processes of buying a VRV unit for my house. There are daikin VRV-III available in the market where I live and VRV 4 will be available in 4-6 weeks. I will use the unit only for cooling purpose for 3 months a year since I have a seperate heating system already installed. Do you think that it will be worth for me to wait for the model? Please note that worth means I need to bear hot weather till mid August. I will appreciate your input.

    I'm surprised that you need a VRV 4 system for your house, unless you are very rich and have multiple rooms.

    Wouldn't a simple 'split' or 'multi split' system suffice?

    And if you are very rich, best choice is MHI, Samsung S or ME
