    Daikin REYQ14P8Y1B - VRV III - Address Issues



    Hello All,

    We have a site with a Daikin REYQ14P8Y1B - VRV III , connected to 11x Floor Mounted Units, BC Box's ( BSVQ16OPV1) and one I touch centralised controller ( controller also controls 1x VAM Unit - VAM1500FA8VE ) - installed in 2008.

    Due to refurbishment of the site we have had to remove one of the floor mounted units from the circuit. The unit removed was 1 of 4 units controlled via 1 BC Box.

    Having removed the unit and pipework we have now pressure tested and recharged. On trying to run the unit we constantly get a U4 error - Communication Error ( before the unit was removed all worked well)

    We have performed a system reset from the condenser but still the U4 error appears.

    The centralised controller is still showing the removed unit , could this be the issue??

    Any help would be appreciated.

    Thanks in advance

    You can also connect a service checker and delete the removed unit and reconfigure the system.
