Outline
About this document
This guide provides procedures that should be followed for the successful implementation of the
Daikin iLINQ controller. For more detailed information on any of the features or wiring, please
refer to the Daikin iLINQ User Manual and the wiring diagram provided with the unit.

DAIKIN ILINQ QUICK START GUIDE 4
Installation
Controller Power
Before applying power to the controller, check the wire terminations at each terminal
block for any loose wires and verify that the 24VAC power wiring at terminal J1 is
correct. The transformer secondary, wired to G0, must be connected to earth ground. Using a
supply voltage other than specified may cause damage to the controller.

DAIKIN ILINQ QUICK START GUIDE 5
Space Temperature Sensor
The Space Temperature Sensor is installed on the wall in the space served by the rooftop unit
to provide feedback of space temperature conditions to the controller. The unit will not operate
without a properly installed Space Temperature Sensor. The sensor should be installed
approximately 4 feet above the finished floor or per site requirements and should be located to
avoid exposure to direct sunlight, other heat sources, and drafts from HVAC supply vents.
Wiring Example: No wiring for the push button override feature is required if the jumper in the
sensor is left in the factory default “Short Sensor” position. If the jumper is moved to the
“Separate Input” position, the O/R terminals must be wired to the Remote Start Stop digital input
for the push button override feature to be functional. In some cases, controller terminal J6 may
be factory wired to a more easily accessible set of terminals in the unit control box. Refer to the
wiring diagram supplied with the unit for additional details.

DAIKIN ILINQ QUICK START GUIDE 6
Supply Air Temperature Sensor
The Supply Air Temperature Sensor provides feedback of the unit’s leaving or discharge air
temperature to the controller. The unit will not operate without a properly installed Supply Air
Temperature Sensor. The sensor is factory installed in the blower compartment. For best
performance, the sensor should be relocated to the supply air duct approximately 10 feet
downstream of the unit.
Wiring Example: The sensor is wired between U1 on terminal J2 at the controller and ground.
In some cases, controller terminal J2 may be factory wired to a more easily accessible set of
terminals in the unit control box. In this case, the sensor is wired between DAT and AG on the
control box terminals. Refer to the wiring diagram supplied with the unit for additional details.

Onboard Display Access
To access the Main Menu, press the MENU button. At the user login screen, use the UP,
DOWN and ENTER buttons to enter 0000 for standard User level access or 1954 for Service
level access. Standard user level access allows for modification of time schedules and common
setpoints. Service level access allows for unit configuration changes to be made. If the user
passwords have been modified, the new User or Service password must be used instead of the
default passwords listed here. After successfully logging in, the Main Menu is displayed.
Navigate through the Main Menu screens using the UP and DOWN buttons to highlight menu
options and pressing the ENTER button to select.

DAIKIN ILINQ QUICK START GUIDE 8
Configure Date/Time
From the Main Menu, navigate to Settings and press ENTER. Navigate to the Date/Time option
and press ENTER. Verify that the current timezone is correct for the region where the controller
is installed. If the timezone needs to be updated, press ENTER to enter the timezone settings
screen and use the UP, DOWN and ENTER buttons to select the New Timezone from the pre-
defined list in the controller. Set the Update Timezone setting to Yes and press ENTER. The
timezone setting must be set correctly prior to configuring the current time since this will
automatically add/subtract hours from the current time when changed. Use the DOWN button to
scroll to the next Date/Time Settings screen and verify that the current date and time are
correct. If the date or time need to be updated, press ENTER to enter the date/time screen and
use the UP, DOWN and ENTER buttons to update the date and time settings.
Configure Time Schedule
The controller time schedule is used to determine when the unit is considered to be occupied
and unoccupied. The default time schedule is occupied between 7:30 AM and 5:30 PM Monday
through Friday. When the schedule option is selected from the main menu, the weekly and
holiday schedule events can be viewed or modified. Press the UP and DOWN buttons to scroll
through schedule event screens for each day of the week, holiday events, and holiday date
configurations. Each day of the week has four Schedule Events that are user configurable. The
Schedule Events are composed of a Start Time and an End Time for occupancy. Setting the
Start Time equal to the End Time is considered unoccupied all day. Setting the Start Time to
12:00 AM and the End Time to 11:59 PM is considered occupied all day.

DAIKIN ILINQ QUICK START GUIDE 9
Pressing the ENTER button on a weekday or holiday event screen selects the Event1 Start
Hour. The UP and DOWN buttons can be used to modify the value. Pressing ENTER accepts
the new value and selects the Event1 Start Minute. The UP and DOWN buttons can be used to
modify the value. Pressing ENTER accepts the new value and selects the Event1 AM/PM
designation. Use the UP or DOWN button to toggle the value and press ENTER to accept. This
process isrepeated for the start and stop time settings for the four events. Additional
information on time schedule settings isprovided in the Daikin iLINQ User Manual.
Unit Configuration Settings
Select the Unit Configuration option from the Main Menu to verify that the unit configurations
are correct. Many of these settings are set at the factory to match the unit where the controller
isinstalled but should be confirmed, and others are determined by site preferences or field-
installed options. Additional information on unit configuration settings isprovided in the Daikin
iLINQ User Manual.
•Changing the Control Mode from DDC to TSTAT configures the controller to accept
commands from a traditional thermostat instead of using the DDC controller application
logic. Follow wiring modification steps outlined in the Daikin iLINQ User Manual.
•Setting Blower Cycling to Yes allows the main blower to be cycled off during occupied
hours when there is no need for cooling or heating for applications where continuous
fresh air ventilation is not required.
•If an economizer option has been installed on the unit, verify that the Economizer setting
has been set to Installed or Installed With CO2 as needed.
•Setting the Sensor Source selection of a sensor to Network causes the controller to use
the sensor value from the LonWorks®or BACnet®communication interface instead of
the onboard wiring connections.
•Change the Schedule Source from Onboard to Remote if the Remote Start Stop input is
to be used for occupancy instead of the defined time schedule. Set to Force Occupied
or Force Unoccupied to bypass scheduling.

DAIKIN ILINQ QUICK START GUIDE 10
Temperature/Humidity Setpoints
Select Temperature/Humidity Setpoints from the Main Menu. Scroll through the setpoints and
modify factory settings per site requirements. Additional information on temperature and
humidity setpoints is provided in the Daikin iLINQ User Manual.
Timers/Delays
Select Timers/Delays from the Main Menu. Scroll through the timers/delays and modify factory
settings per site requirements. Additional information on timers and delays is provided in the
Daikin iLINQ User Manual.

DAIKIN ILINQ QUICK START GUIDE 11
Modify TCP/IP Settings
If the controller is to be connected to a TCP/IP network, the TCP/IP settings must be provided
by the network administrator. From the Main Menu, navigate to Settings and press ENTER.
Navigate to the Communication option and press ENTER to view and modify the TCP/IP
settings. Set the DHCP setting value to On/AutoIP if the network will automatically assign IP
addresses to connected devices. If a static IP address is used, enter the appropriate IP
Address, Subnet Mask, Default Gateway, and DNS Address settings. The updated TCP/IP
settings do not become effective until the controller application is restarted. Restart the
controller by setting the Update value to Yes and pressing ENTER.
View Active Alarms
If the controller detects an abnormal condition such as a missing sensor or that the economizer
damper actuator is disconnected, an alarm is generated and can be viewed through the
onboard display. The LED at the ALARM button illuminates red when there is an active alarm.
View any active alarms by pressing the ALARM button and using the UP and DOWN buttons to
scroll if there is more than one active alarm. Each alarm provides a brief description of the alarm
and up to two related values that were logged at the time that the alarm was generated to help
determine the cause of the alarm. Once the cause of the alarm has been corrected, the alarm is
cleared and the unit resumes normal operation. If the alarm requires a manual reset, press and
hold the ALARM button for 3 seconds to clear the alarm.
Test and Balance
During startup, commissioning, or troubleshooting of the unit, it may be necessary to force the
controller into a certain operating mode so that equipment operation can be verified. From the
Main Menu, navigate to Test/Balance and press ENTER to view the Force Mode screen. Force
Mode allows the user to select from a set of predefined modes. Depending on the Force Mode
selected, the controller commands the necessary outputs based on the unit configuration. In

DAIKIN ILINQ QUICK START GUIDE 12
Force Vent Mode, the blower speed and the economizer damper position can be set to user-
defined values. This can be used to help during unit startup when airflow may need to be
confirmed or adjusted, and the economizer damper position settings need to be determined to
meet fresh air requirements.
Force Mode is intended to be used for short time intervals for the startup or test/balance
procedures. If the unit has been in a Force Mode for longer than 30 minutes without any
changes being made to any of the Force Mode settings, the unit returns to normal operation.
If it is determined that economizer minimum positions or blower speed settings need to be
adjusted to meet airflow requirements for the site or to match the airflow tables in the unit IO
manual, navigate to the Econ/Blower Settings screen. From the Main Menu, navigate to
Econ/Blower Stpts and press ENTER to view or modify all of the economizer and blower speed
settings.

DAIKIN ILINQ QUICK START GUIDE 13
Export Parameters
After the controller configuration is completed, it is recommended that the controller parameters
be saved to an export file. This file can be used at a later time to return the controller to the
original site settings if incorrect modifications are made, or if the controller application is
upgraded and these settings return to default. From the Main Menu, navigate to Settings and
press ENTER. Navigate to the Export/Reset option and press ENTER. Under Parameters
Import/Export, select Export, select the preferred Memory Type, enter a value for the Export File
Name, and set the Confirm value to Yes. Selecting Internal Flash Memory as the Memory Type
will save the file to the controller’s internal memory. Selecting USB will save the file to a
connected USB device. Reference the web interface export parameters section of this guide for
instructions on accessing and retrieving the export file from the controller’s internal memory.

DAIKIN ILINQ QUICK START GUIDE 14
Using the Web Interface
PC Configuration
To view the web interface, the PC being used and the controller must be configured to be on the
same TCP/IP network. The controller default IP address is 192.168.1.16 and the default Subnet
Mask is 255.255.255.0. If the TCP/IP settings have been modified, the PC configuration settings
needed to connect to the controller will be different than the example given here.
Connect an Ethernet cable between the PC and the controller using one of the two available
controller Ethernet ports. Modify the computer’s network settings so the IP address is in the
range: 192.168.1.1 to 192.168.1.254 (excluding 192.168.1.16 which is used by the controller).
The Subnet Mask should be set to 255.255.255.0 and the Default Gateway can be left un-
configured.
