Before you begin
NOTICE
WinCIS version 2.1.4 or later must be used to congure 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 ash for data packets received by the actuator
from the MS/TP network. The TX LED will ash 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 ashing 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 Conguring 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 nished.
• 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 Cooling or Heating 2561
VAV with Electric Reheat or Baseboard Radiation 2562
VAV with Hot Water Reheat 2563
VAV Series Fan Powered with Electric Heat 2564
VAV Series Fan Powered with Hot Water Reheat 2565
VAV Parallel Fan Powered with Electric Heat 2566
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
ve minutes to complete after this delay. The air damper closes
during the rst calibration.

Enabling actuators
CAUTION
The controller’s DOs control only 24 Vac loads.
The maximum rating is 12 VA for each DO.
The points that determine actuator run times are:
• MTR 1 TIMING
• MTR 2 TIMING
• MTR 3 TIMING
Your application may not have or use all three points.
1. Use and/or to set run time(s) for actuator(s) used by your
application.
2. For damper rotation angles other than 90°, set DMP
ROT ANG to the appropriate value. The names of these
points vary.

Specifying motor setup
CAUTION
If an Autozero Module is used, do not enable MTR3 (valve 2).
NOTICE
When MTR SETUP is changed, all enabled actuators will
calibrate. Wait until each actuator has completed its calibrating
before continuing.
MTRSETUP determines which actuators are controlled by the
application and whether they are direct or reverse acting. Set
MTRSETUP according to Table 4.
Table 4: Motor Enable/Reverse Values for MTR SETUP
(Point 58)
Enabled Enabled and Reversed
Motor 1 (damper)
Motor 2
Not used 1 (default) 3
Enabled 5 7
Enabled and Reversed 13 15
Verifying actuator setup
Command all actuators closed. Verify that they close and
remain closed. If not, adjust the setting for MTRSETUP
according to Table 4.
If any of the actuators still do not close completely, then
the actuators have been installed or set up incorrectly. See
the installation instructions or contact your local Daikin
representative.
Setting the number of heat stages or
valves
CAUTION
For installations using electric heat coils, never set min airow
settings to 0 (zero). Equipment damage can occur if electric
heat is ON without airow.
Depending on the application, HTG STG CNT or VLV CNT (if
present) refers to electric heat stages or valves used (enabled),
some point names may vary.
• Set VLV CNT to the number of valves used for water or
steam valve applications (1 or 2)
• Check the hardware to verify the number of electric heat
stages wired to the controller (1 to 3) and set HTG STG
CNT to the value for electric heat appliactions

Enabling autozero module
CAUTION
If an Autozero Module is used, do not enable MTR3 (valve 2).
NOTICE
For a controller without an Autozero Module, the damper
is commanded closed to get a zero airow reading during
calibration. For a controller with an Autozero Module, the
damper is closed only for the rst calibration after controller
initialization or power up.
If an Autozero Module is used, enable it by setting CAL
MODULE to Y.
Selecting automatic calibration option
NOTICE
The air velocity sensor must be calibrated at least once every
24 hours. Make sure that the sensor has been calibrated
before balancing takes place, as this will affect the balancer’s
results.
NOTICE
Options can be combined by summing their numbers. For
example, to calibrate as in Options 1 and 2, set CAL SETUP
to 3.
Using Table 5 set CAL SETUP to the value that best meets
your job requirements.
If appropriate, change CAL TIMER from the default of 12
hours. This setting applies only if your choice for CAL SETUP
includes Option 4.
Table 5: CAL SETUP Values
CAL SETUP (Point 95) Description
0Calibration occurs ONLY when the point CAL AIR
(Point 94) is set to YES
1
Calibration occurs when the eld panel commands
a day/night mode changeover. Actual calibration is
subject to a time delay of 0, 1, 2, or 3 minutes. This
delay is determined by the point CTLR ADDRESS
(Point 1) divided by 4. The remainder is the time
delay in minutes.
Example: If CTLR ADDRESS = 11, then the
controller will wait 3 minutes (11 ÷ 4 = 2 R3) after it
receives the day/night mode changeover command
before beginning the calibration routine.
2Calibration occurs immediately after the override
switch is depressed.
4
(factory default value)
Calibration occurs on the time interval set in the
point CAL TIMER (Point 96).
For example, if CAL TIMER = 12, then the
calibration period is12 hours. Actual calibration is
subject to a time delay based on the value of CTLR
ADDRESS.
See the example in Option 1. This is the
recommended option when using a controller with
an Autozero Module.
Setting room temperature setpoints
NOTICE
If STPT DIAL is set to YES, do not set the DAY (or OCC)
setpoints; the value of RM STPT DIAL will be used for these
points.
•DAY (or OCC) cooling setpoint
•DAY (or OCC) heating setpoint
•NGT (or UOC) cooling setpoint
•NGT (or UOC) heating setpoint
If the room temperature sensor has a setpoint dial that will be
used, set STPT DIAL to YES. Otherwise, set STPT DIAL to NO.
Set the room temperature setpoints to the desired values
(some points are not present in certain cooling only
applications).
Set RM STPT MIN and RM STPT MAX for the minimum and
maximum allowable room temperature setpoints, respectively.
Valid values range from 55°F to 95°F (13°C to 35°C). Default
values are 55°F (13°C) for RM STPT MIN and 90°F (32°C) for
RM STPT MAX.
Setting override time
If using night/unoccupied override, set OVRD TIME to the
number of whole hours that an override should last. If OVRD
TIME equals 0 (default), then this feature is disabled.
Enabling Wall Switch
If a wall switch is used for day/night (Occ/Unocc) control,
enable it by setting WALL SWITCH to YES.
Setting Duct Area
If provided, enter the duct area (sq ft or sq m) into DUCT
AREA (and also into HTGDUCT AREA, where applicable) and
continue to Setting ow coefcient on page 7.
If you do not know the duct area, use Table 6:
Table 6: Duct Area Calculation
Area = Round Duct Rectangular Duct
Area in Sq. Ft.
(Dimensions in inches) (π x R2)/144 Width × Height/144
Area in Sq. M.
(Dimensions in centimeters) (π × R2)/10,000 Width × Height/10,000

Setting ow coefcient
1. Set FLOW COEFF to the appropriate value found in
Table 6. This value is a starting point for the air balancer.
2. To ne tune the ow coefcient use the following formula:
new ow coefcient = (actual volume / TEC volume)
× old ow coefcient
The actual volume is the actual value obtained from the
balancer’s measurements. The TEC volume is the value
obtained from AIR VOLUME.
3. If the TEC volume is not within 5% of the actual volume,
repeat the procedure until it is within 5%.

Setting airow setpoints
CAUTION
If using electric heat in a unit without a terminal fan, do not set
HTG FLOW MIN to 0 (zero). Equipment damage may occur at
0 (zero) CFM with electric heat ON.
NOTICE
Maximum ow(s) must be set ≥ minimum ow(s).
NOTICE
For Applications 2562, 2563, 2564, and 2566, HTG FLOW
MAX should be less than CLG FLOW MAX. Otherwise, cold
supply air may cool rather than heat the space in heating
mode. A typical setting for HTG FLOW MAX is 50% or less of
CLG FLOW MAX.
1. Set CLG FLOW MIN to the desired minimum cooling
airow setpoint.
2. Set CLG FLOW MAX to the desired maximum cooling
airow setpoint.
Applications 2561 - 2567:
1. Set HTG FLOW MIN to the desired minimum heating
airow setpoint.
2. Set HTG FLOW MAX to the desired maximum heating
airow setpoint.
Setting room temperature offset
(optional)
NOTICE
The Room Temperature Offset feature is optional.
When the room has stabilized to within 5°F, take a precision
temperature reading at the room temperature sensor, record
any difference between this reading and the value of ROOM
TEMP and set this difference value (to the nearest 0.25°F) into
RMTMP OFFSET.
Example:
If the actual room temperature is 72.0°F, and the value of
ROOM TEMP is 73.0°F, then the value entered into RMTMP
OFFSET is –1.0. In this case, the value of ROOM TEMP would
read 73.0°F, but the value of CTL TEMP would read 72.0°F.
CTL TEMP = ROOM TEMP + RMTMP OFFSET

Performing the automated checkout
NOTICE
Multiple failures are added together and displayed as one
value. For example, if the RTS failed (1) and the controller
could not reach CLG FLOW MAX (16), CHK STATUS
displays 17.
The Daikin VAV Actuator has a built-in checkout procedure
that can be manually initiated at any time after the controller
has been installed. This procedure tests all of the necessary
I/O and ensures the controller has the ability to operate within
the set airow range, between CLG FLOW MIN (Point 31) and
CLG FLOW MAX (Point 32).
To perform the checkout procedure, set CHK OUT (Point 66) to
YES. When the procedure has completed, CHK OUT returns to
NO and the results are displayed in CHK STATUS (Point 70),
Table 7.
Table 8: Possible Failure Value and Description.
