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 15
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
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
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.
