Some of our RTD and FDP3 products may have similar Modbus register lists. But you cannot use an FDP3 with a Daikin unit or an RTD with a Toshiba unit.
The reason is:
Our FDP3 products interface to Toshiba's wired remote controller network TCC-Net AB.
Our RTD products interface to Daikin's wired remote controller network P1P2.
TCC-Net AB and P1P2 are not the same.
