Connecting To Other Equipment - Daikin DCC601A51 Installer's Reference Manual

7. Electric wiring
This chapter will describe the procedure to connect the intelligent Tab
Controller kit components with Daikin devices and other equipment.
WARNING
Do not turn on the power supply before all wire
connections are completed. Not doing so may cause an
electric shock.
After the wiring is completed, double-check that all wires
are connected correctly before turning on the power
supply.
All field supplied parts, materials and electric works must
comply with the applicable legislation.
INFORMATION
At the time of writing, some connectors are not active, but
provided for future use.
7.1.

Connecting to other equipment

For all wiring requirements, refer to
page 26.
7.1.1. Connecting DIII-NET compatible equipment
DIII-NET is a unique air conditioning equipment communication
capability developed by Daikin. Using DIII-NET, you can centrally
control multiple DIII-NET-compatible air conditioning devices by
connecting them to your intelligent Tab Controller.
To connect the DIII-NET communication line, use the F1 and F2
terminals on the upper part of the I/O module, as shown on the
following diagram.
These two terminals have no polarity. An example of connecting
more than two air conditioning devices is shown in the following
wiring diagram.

7.1.2. Connecting digital input and output devices
The intelligent Tab Controller can be connected with an external
signal input device for stopping air conditioners, with electric energy
meters for calculating the electricity usage of individual air
conditioners or other devices.
Connect the contact input lines or pulse input lines to the Di1, Di2,
Di3, Di4 and COM terminals of the connector on the bottom of the I/O
module. The function of each terminal is as shown in the following
wiring diagram.
The function assignment, however, may be changed at a later time.
For more details on the required pulse width and interval, refer to
"15.8. Wiring requirements" on page
function assignment, refer to
descriptions" on page 19.
INFORMATION
At the time of writing, the digital output connection Do is
not active, but provided for future use.

normally open (A-type) or normally closed (B-type) contact
inputs, or as pulse inputs.
c [Do] Provided for future use.
NOTICE
When the forced stop contact input is closed, a stop

signal is sent to all connected devices. There is no
hard guarantee that all devices are actually stopped
and remain stopped during the time the forced stop
contact input is active.
When the forced stop contact input is closed, the

connected devices cannot be restarted unless the
contact input is reopened.
NOTICE
 The COM terminals are all connected internally. So,
you can use any one of them. However, you can only
connect up to two wires simultaneously to each COM
terminal.
If applicable, connect the I/O module's COM terminal

to the negative side of the device terminals.
