Number of Daikin units
One Comm. box and three RTD units can be connected to a single
AK-PI 300.
If there are more, use 2 (x) AK-PI 300 units.
Up to two AK-PI-300 units can be connected to a single system
manager, i.e. up to 2 Comm. boxes and 6 RTD units.
If there are two AK-PI 300 units, the connection to the system
manager is led via a router or a switch.
(Up to 32 outdoor units, 30 booster units and 64 indoor units can
be connected to a single Comm. box. Up to 16 indoor units can be
connected to a single RTD unit.)
Addresses
In principle there are three types of addresses:
IP addresses
Both the system manager and the AK-PI 300 must have an IP
address set.
The address can be either dynamic or static – the desired value is
selected with a setting. If static is chosen, an address must also be
set.
If the system can be accessed externally, the setting in the
system manager AK-SM 720 must always be set to static so that
the external connection always recognises the address and can
communicate with the unit.
(The IP address is set in a menu).
Network addresses
There must always be one and only one master system manager
on a network. This is defined with the address setting = 1. This
system manager controls the communication to all the other
controllers on the network. The PI unit is perceived as a controller
on the network and its address can be viewed in the IP list. (Up to
two PI units can be connected to the system manager, which is
master - i.e. has address =1)
(You set the network address on the front of the system units and
on the front of the PI units.)
Set the system manager to address 1.
If there are several system managers (slave network), set these to
addresses 2 to 10.
Each PI unit is set with a separate address. Select 12 or higher, e.g.
21.
Interconnection
When setting the system manager, a menu must also be set in
which the relevant AK-PI 300 chooses the network. The system
manager then knows the way to the different Daikin units. The
system manager must be version 1.20 or later.
Controller addresses
All controllers on the same network must have different addresses.
In other words, all controllers that are connected to a system
manager on either:
• the LON communication
• the MODBUS communication
• the DANBUSS communication or
• Daikin
communication.
Start with the addresses on Daikin RTD-NET.
Then for DANBUSS, if needed (via AK-PI 200).
A Daikin Comm. box registers 3 addresses.
After this, add the addresses on the Daikin Comm. box connec-
tions. (These address numbers can be offset. See next page.)
The addresses on the LON and MOD buses can be set higher.
No more than 200 controllers can be connected to a system
manager.
