Before you begin
NOTICE
WinCIS version 2.1.4 or later must be used to configure Daikin
BACnet controllers.
If WinCIS does not communicate (through the HMI port / RTS
sensor), try a different baud rate. The default buad rate is 1200
(allowable baud rates are: 1200, 9600, 19200, 38400 and
76800).
Figure 1: Actuator Components
Communication and DO indicators
The BACnet actuator has LEDs to indicate communication
(yellow) and DO [digital output] status (green).
The RX LED will flash for data packets received by the actuator
from the MS/TP network. The TX LED will flash for data
packets sent by the actuator to the MS/TP network. Each DO
(3 to 6) has an associated LED located above its termination
point. This LED point is ON when the accociated DO is
commanded ON, otherwise it is OFF. The BACnet actuator
will attempt to communicate with other devices as soon as
it powers up. The TX LED will start flashing as it attempts to
connect and transfer data.
Setting controller address
NOTICE
For BACnet, the controller address is the same as the BACnet
MAC address.
NOTICE
Set the controller address and MS/TP network baud rate prior
to connecting the controller to the network.
• Set the controller address by setting CTLR ADDRESS
to the appropriate number, see Configuring BACnet
Parameters
• The start-up is complete
Setting the application
NOTICE
You can continue the startup procedure while calibration is
underway. However, the controller will ignore commands to
control end devices (such as the damper) until calibration of
the air velocity sensor is finished.
• Add the TEC to your job database and select one of the
following applications from Table 1
Table 1: Daikin BACnet Actuator—Electronic Output
Applications
Application Description Application Number
VAV Cooling Only 2560

VAV Parallel Fan Powered with Hot Water Reheat 2567
VAV Slave Mode 2597
After you set the application, the controller goes through a
shut-down/load sequence as it switches from slave mode
to the application selected. When the application loads, the
calibration cycle begins.
At the start of the calibration cycle, the controller
automatically sets CAL AIR to YES. CAL AIR returns to NO
when the cycle is complete.
The air velocity sensor calibration cycle begins within three
minutes of an application start-up or initialization, depending on
the controller’s address. The calibration cycle takes from two to
five minutes to complete after this delay. The air damper closes
during the first calibration.
