Daikin VRV 3 pipe changing mode

[multisync]

This is the problem with Daikin VRV.

In aplication like hotel when access to all indoor units is always a problem then you really need to be able to get data from each indoor unit like,,, mode / set temp / EEV opening / return air temp / gas & liquid refrigerant temps from a remote location.
If other manufacturers VRF system is used you can get all that data from every indoor unit by service engineer setting at the outdoor circuit board & outdoor circuit board LED display.
No need for any service checker laptop computer.

The outdoor unit compressor slow down for pressure equalisation every time an indoor unit changes mode has been a big disadvantage for the VRV system.
Look at the new BSV box & you will find that instead of soleniod valves there is now 5 EEV valves !
Trouble shooting any problem with the new BSV boxes without the service checker I suspect will be an even larger challange.

Do you have a checker as we may need assistance to quickly get to the bottom of this ...
