User manual TOSHIBA RBC-LG1 APPLICATION CONTROL MANUAL

[. . . ] TCC-NET installation should follow Toshiba installation specifications. Terminals R1-R2 connect to fault monitoring or indication equipment according to the specified rating of the relay. The FDP2 is powered from the TCC-NET and requires no extra power supply. 18. 60 Indoor Unit 63. 00 87. 00 Fault Monitoring + Locked Cooling Preset 18 8 Units max ALL DIMENSIONS IN MM NOT TO SCALE FDP2 Description The FDP2-F is a monitoring and control interface for the Toshiba Digital Inverter and SMMS range of air-conditioners. TCC-NET TCC-NET D-BUS RELAY A B D1 D2 C R1 R2 Fault Reporting The FDP2-F Interface detects all indoor and outdoor faults occurring in TCC-NET compatible Toshiba air-conditioners and reports them by closing relay contacts R1-R2. [. . . ] The FDP2-F is connected on the TCC-NET network with or without a standard remote controller and detects any faults that can be displayed on the controller for up to 8 units. Red and Green LEDs Indicate Fault/No Fault state. A B To fault monitoring Fault Monitoring + Locked Heating Preset 23 Toshiba Remote Controller 8 Units max Control Functions GROUP CONTROL. Multiple FDP2 Interfaces can be connected to form large groups of units controlled from a single remote controller. Remote controller operation can be locked and various different preset run conditions can be sent from the FDP2. Pairs of FDPs can operate duty/standby control with 24 hour alternating duty, and changeover on fault. In conjuntion with an FDP2-BMS unit control can be achieved through potentiometer and volt-free contact inputs as well as via BMS integration. FDP2 interfaces can be supplied in custom configurations to suit specific applications.

Address 1 to 15 are FDP2 SLAVE addresses that can be used to create large control groups. NETWORK INSTALLATION The D-Bus network requires a twisted pair cable connecting terminals D1 and D2 on each FDP2 as shown below. Terminal D1 must be connected to all other D1 terminals. Terminal D2 must be connected to all other D2 terminals. In addition the common terminal C on all devices must be connected together. If a shielded cable is used then the shield can be used for this purpose. The network must be installed as a point to point BUS configuration, Star and Ring connections must NOT be used. Address 0 (MASTER) 21 8 Units max 8 Units max D-BUS 16 FDP2 max Address 1 (SLAVE) D-BUS 16 FDP2 max Address 1 (SLAVE) The MASTER FDP2 can be configured using SW1 and SW2 to operate using one of the three preset modes Heat, Cool or Auto.
