I have an older VRV II-S system RXYMQ-M. There were four ducted FXSQ-M units connected and recently I replaced one air handler due to coil failure. The new air handler is FXMQ-TB. With this upgrade I added Nav controller BRC1E73. Now I have two Nav BRC1E71 controllers (one controls two FXSQ air handlers the other controls one FXSQ) and one 1E73 unit that controls the new FXMQ.

I’m looking for the fan off field setting when thermo is off for the new FXMQ air handler. I have it set properly in heat mode (22-3-3) and I thought the correct off fan setting in cooling was 22-6-3, but the fan does not go off. Any help on this is appreciated.
