IntesisTM INMBSDAI001R000 User’s Manual r3.8 EN 2. Connection The interface comes with a plug-in terminal block of 2 poles to establish direct connection with the AC indoor unit. It comes as well with a plug-in terminal block of 2 poles to establish direct connection with the Modbus RTU EIA-485 network. 2.1 Connect to the AC indoor unit The INMBSDAI001R000 connects directly to the Daikin P1P2 Bus, which is not provided within the interface.

IntesisTM INMBSDAI001R000 User’s Manual r3.8 EN 2.2 Connection to the EIA-485 bus Connect the EIA-485 bus wires to the plug-in terminal block (the one of two poles) of INMBSDAI001R000 and keep the polarity on this connection (A+ and B-). Make sure that the maximum distance to the bus is 1,200 meters (3,937 ft). Loop or star typologies are not allowed in the case of the EIA-485 bus. A terminator resistor of 120Ω must be present at each end of the bus to avoid signal reflections.

IntesisTM INMBSDAI001R000 User’s Manual r3.8 EN 4. Modbus Interface Specification 4.1 Modbus physical layer INMBSDAI001R000 implements a Modbus RTU (Slave) interface, to be connected to an EIA-485 line. It performs 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 INMBSDAI001R000 User’s Manual r3.8 EN 4.2.3 Considerations on Temperature Registers • AC unit temperature setpoint (R/W) (register 4 – in Protocol address / register 5 – in PLC address): This is the adjustable temperature setpoint value that must be required by the user. This register can be read (Modbus function 3 or 4) or written (Modbus functions 6 or 16).

IntesisTM INMBSDAI001R000 User’s Manual r3.8 EN This register always informs about the current temperature setpoint which is being used by the indoor unit and it is also includes the temperature setpoint that will be shown by an additional remote controller from Daikin connected to the indoor unit, if it is present on the system.

IntesisTM INMBSDAI001R000 User’s Manual r3.8 EN 4.6 EIA-485 bus. Termination resistors and Fail-Safe Biasing mechanism EIA-485 bus requires a 120Ω terminator resistor at each end of the bus to avoid signal reflections. In order to prevent fail status detected by the receivers, which are “listening” the bus, when all the transmitters’ outputs are in three-state (high impedance), it is also required a fail-safe biasing mechanism.

IntesisTM INMBSDAI001R000 User’s Manual r3.8 EN 8. Annex 1: Master/Slave of Operation Mode The Master/Slave of Operation mode only applies under the following conditions: 1. The AC system is VRV 2. The VRV system uses a Heat pump as outdoor unit 3. There more than one indoor unit in a unique system working at different modes (Table 8.1) If they are not matched the parameter is going to be ignored. The Heat pump outdoor unit of a VRV system can only work in one mode (either Heat, Cool or fan).
