RBC-FDP3-PE Air Conditioning
FDP2 Description
The FDP2-F is a monitoring and control interface for the Toshiba Digital
Inverter, SHRM and SMMS range of air-conditioners.
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.
Control Functions
GROUP CONTROL. Multiple FDP2 Interfaces can be connected to form large groups
of units controlled from a single remote controller.
OPERATION PRESETS. Remote controller operation can be locked and various
different preset run conditions can be sent from the FDP2.
DUTY/STANDBY. Pairs of FDPs can operate duty/standby control with 24 hour
alternating duty, and changeover on fault.
HARDWIRED CONTROL. In conjuntion with an FDP2-BMS unit control can be achieved
through potentiometer and volt-free contact inputs as well as via BMS
integration.
CUSTOM CONTROL. FDP2 interfaces can be supplied in custom configurations to
suit specific applications.
Warnings and Cautions
Do not exceed the specified fault relay ratings
Mounting
The FDP2 should be mounted using the keyhole mounting points as indicated in
the adjacent diagram.
The FDP can be mounted horizontally or vertically.
Basic Cable Installation
Cabling should be a minimum 0.75mm² throughout. Terminals TCC-NET A/B connect
to the Toshiba TCC-NET. 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.

Standard Operation
FDP2 Configuration Switches
The FDP2 has a number of standard configurations that can be set using
switches SW1 to SW7 shown above. Factory configuration is configured with all
switches OFF. In this mode the FDP2 operates as a standard fault monitoring
device. Additional preset modes are available using SW1 and SW2 to operate the
system in preset Heat, Cool and Auto modes*.
Fault Monitoring
Fault Monitoring + Locked Cooling
Preset

Heating Preset
Fault Monitoring + Locked Auto

***** Units that do not support
specific modes such as cooling-only units will operate in fan-only in
unsupported modes.
FDP2 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 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.
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,
FDP2 Group Control
Group control allows up to 16 FDP2s to be connected on a D-Bus local
network. Each FDP2 reports faults for the locally attached units. The FDP2
with address 0 is a MASTER and determines the settings for all systems
connected to FDP2s addressed as slaves. The operating mode of the master is
determined by SW1, SW2 as shown in the Standard Operation configuration
instructions overleaf.
LOCAL CONTROL
With SW1 OFF and SW2 OFF the MASTER FDP2 system operates under the control of
the attached remote controller. SLAVE FDP2 devices will duplicate these
settings to allow large groups to be controlled from one remote controller.
Remote controllers on the slave FDP2s are locked and can be omitted if
desired.
PRESET CONTROL
If the master is configured for Heat, Cool or Auto preset control then the
FDP2 slave units will operate to the same settings as the master. The diagram
below shows the system configured for the Cool preset. See overleaf for SW1,
SW2 settings for Heat and Auto presets.
FDP2 Duty/Standby Operation
SW3 ON for Duty/standby
Duty/Standby will alternately run two systems on 24 hour alternating
run/standby. If a fault occurs on either system then both systems are switched
on until the fault is cleared.
Duty/Standby is achieved using two FDP2 devices, one with Address 0 and one
with Address 1 with a D-BUS connection between the two. SW3 must be switched
ON on both devices to enable the operation.
The MASTER FDP2 can be configured using SW1 and SW2 to operate
using one of the three preset modes Heat, Cool or Auto. Alternatively the
MASTER can be configured for local control, in which case the remote
controller attached to the MASTER FDP2 can be used to set the operating
settings during master duty.
Advanced control
More sophisticated control con be achieved using the FDP2-BMS interface, this
provides a number of inputs that allow external control of unit operation, or
connection to Building Management Systems. The FDP2 interfaces can also be
customised for specific operating requirements. Contact Toshiba for details.
