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

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

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