FDP2 Description
The FDP2-BMS is a monitoring and control interface for the Toshiba Digital
Inverter and SMMS range of air-conditioners.
Fault Reporting
The FDP2-BMS 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-BMS 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.
Control Functions
HARDWIRED CONTROL. Unit control can be achieved through resistance
inputs using potentiometer and volt-free contact inputs.
BMS INTEGRATION. Unit control can be achieved through 1-10V voltage
inputs integrated with BMS control outputs.
GROUP CONTROL. Multiple FDP2 Interfaces can be connected to form
large groups of units.
CUSTOM CONTROL. FDP2 interfaces can be supplied in custom
configurations to suit specific applications.
CONFIGURATION. The FDP2 has a number of standard configurations that
can be set using switches SW1 to SW7.

FDP2-BMS Standard Operation
SW1 SW7
The FDP2-BMS Inputs S1 to S6 allow individual
control of various unit operating parameters. Each
input corresponds to a specific unit setting shown
in the table to the right. If an input is left
unconnected then the corresponding setting will
remain at a preset value.

S1 to S6 cables should be 0.5 to 1.0 mm2 multi-stranded screened twisted
pair. The screen should be earthed at one end only. The maximum
distance from the FDP2 to the input source is 200m.
The configuration switch SW1 changes the inputs S1 to S6 between
Resistance and Voltage modes.

operation can be controlled by

latching switch inputs to inputs S4

With SW1 ON inputs S1 to S6

ranges between 1V and 10V can
be used to modulate each input.
This mode is designed for
interfacing the FDP2-BMS to BMS
voltage outputs.
Each control input has a defined control range under voltage and
resistance mode as outlined in the following tables. Default settings are
applied if the input remains unconnected. These are indicated in the table
by the symbol .

Resistances should be within +/-250 ohms of the quoted value. Open circuit is R>200kΩ.
Voltages should be within +/- 0.25V of the quoted value. Open circuit for V<1V.
Under open circuit conditions the input will revert to its default value.
S1 in resistance mode is designed to be operated using a linear 10kΩ variable resistance.
It is recommended that volt-free contacts or switch mechanisms connected to S4, S5 and S6 have gold
plated contacts to ensure a low resistance circuit when the switch is made.

FDP2-BMS Advanced Operation
ADDRESSING
The FDP2 has the facility to create control groups using multiple FDP2s
connected together on the D-Bus network. In standard configuration up
to 16 FDP2 devices can be connected together. Each FDP2 is assigned
a D-Bus address using the configuration switches SW4 to SW7. Unit
addresses are shown below.
ADDRESS 0
ADDRESS 1
ADDRESS 2
ADDRESS 3
Address 0 is the FDP2 MASTER address. 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.

FDP2-BMS Group Control
Connecting additional FDP2-BMS or FDP2-F controllers as slaves allows
larger groups of units to be controlled from the master.
With S6 open (LOCKED) units operate to the settings S1 to S5 from the
FDP2-BMS master.

FDP2-BMS Slave Input Control
With no inputs connected the FDP2-BMS slave will duplicate the settings
of the FDP2 master. If one or more slave inputs S1 to S6 are connected
then each input on the slave will override the corresponding value sent
from the master. For example if S1 on a slave is connected, then the units
attached to the slave will be sent the local S1 setpoint rather than the
master setpoint. Similarly slave inputs S2 and S3 will override the
corresponding values from the master. If an ON signal is applied to inputs
S4 to S6 then this will override an OFF value sent from the master. The
example below shows a setpoint override on a slave.

Local Restore Mode SW3
SW3 enables Local Restore Mode on master and
slave FDP2-BMS. In this mode the remote
controller settings are saved when the FDP2 enters
central/locked operation. When the remote
controller returns to local operation the saved
settings are restored to the remote controller.
When operating in this mode, a 15 second delay will occur when
unlocking the keypad to allow the previous user settings to be restored.
Local Restore operation is shown in the following figure.

SPECIFICATION
Use solid or stranded 24awg shielded or unshielded twisted pair to
Cat3, Cat4 or Cat5 specification. Use a twisted pair for connections
D1,D2 and an extra core for connection C.
NETWORK LENGTH
Standard installation for total network distances of up to 500m can be
achieved following the basic daisy-chaining method showed in the
above diagram. Network layout should follow a point-to-point
connection, ‘T’ and star connections are not supported.

The switch SW2 on the master allows remote

controllers will unlock when the master remote
controller unlocks
NOTE ON FDP2-F SLAVE OPERATION: FDP2-F interfaces can be used as slaves to FDP2-BMS
interfaces, however the duty/standby mode available in the FDP2-F will no longer operate.
