Setting up the FRENIC-HVAC/AQUA

Node address
Set the node address within the range of 0 to 127 using function code y01 or y11. Setting 128 or
more is treated as 127.
Baud rate
Select the baud rate using function code y04 or y14. The typical baud rate of BACnet is 9600
bits/s. In addition to 9600 bits/s, the FRENIC-HVAC/AQUA can select 19200 and 38400 bits/s.
Selecting 2400 or 4800 bits/s is treated as 9600 bits/s.
Protocol
Select BACnet (y10 or y20 = 5).
Character length, parity, and stop bit
These are fixed in BACnet. No setting is required.
Terminating resistors
The end nodes on a BACnet network must be terminated to avoid reflections on the bus line.
The FRENIC-HVAC/AQUA is equipped with a termination switch to set a terminating resistor
easily. If it serves as a terminating device in a network, the termination switch should be in the
ON position. Otherwise the switch should be in the OFF position.
Note: If an external termination connector is used, the switch should be in the OFF position.
