NETWORK INSTALLATION	Address 0 (MASTER)
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	8 Units max

used.

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

PRESET CONTROL

If the master is configured for Heat, Cool or Auto preset control then the

More sophisticated control con be achieved using the FDP2-BMS

FDP2 slave units will operate to the same settings as the master. The
