IntesisTM INMBSDAI001I000 User’s Manual r2.3 EN 4. Modbus Interface Specification 4.1 Modbus physical layer INMBSDAI001I000 implements a Modbus RTU (Slave) interface, to be connected to an EIA485 line. It performs an 8N2 communication (8 data bits, no parity and 2 stop bit) with several available baud rates (2400 bps, 4800 bps, 9600 bps -default-, 19200 bps, 38400 bps, 57600 bps, 76800 bps and 115200 bps). It also supports 8N1 communication (8 data bits, no parity and 1 stop bit). 4.

IntesisTM INMBSDAI001I000 User’s Manual r2.3 EN This register reports the temperature that is currently used by the Daikin indoor unit as the reference of its own control loop. Depending on the configuration of the indoor unit, this value can be the temperature reported by the sensor on the return path of the Daikin indoor unit or the sensor of its Remote Controller. It is a read-only register (Modbus functions 3 or 4).

IntesisTM INMBSDAI001I000 User’s Manual r2.3 EN scenario, the setpoint value shown or written in register 4/5 will always be the same as the current setpoint value of the indoor unit. o • Notice that, the use of the “external temperature reference” (register 22/23) (e.g., writing a value different from -32768 / 0x8000 in it) has the following relevant consequences: ▪ The mechanism of “Virtual Temperature” is applied.
