APPLICATION
This system is designed to work with
Daikin One+ Smart Thermostat only.
(Not available for CTK04 or other thermostats)
This system can be paired with conventional
gas furnaces (single-stage or two-stage).
Allowed indoor and outdoor unit combinations
Please refer to DAIKIN CITY or PartnerLink for the available indoor and
outdoor unit combinations.
NOTICE
All AHRI (Air Conditioning, Heating and Refrigeration Institute) system
ratings are accessible in the unitary matchup tool via DAIKIN CITY or in
the DAIKIN system congurator tool via PartnerLink.
Allowable Air ow CFM range
Rated performance is based on fan speed changing under low load
conditions. This lower airow will also provide best dehumidication and
comfort. The fan taps must be properly set to provide rated airows. Please
refer to Specication Sheets for correct airow rates. Any airow setting
beyond the range specied may cause condensation, dehumidication, or
compressor reliability issues.
Check the installation restrictions of each unit.
The latest Installation Manual can be obtained from the website“DAIKIN CITY
(Installation Manual/Unitary Split System)”or“PartnerLink (Info-FinderPlus/
Literature)”.

100 ft, and from the adapter to Daikin One+ Smart Thermostat should be less than 125 ft.
Wire with thermostat, indoor a-coil, outdoor unit and gas furnace according to the
wiring diagram.
Wiring is subject to change. Always refer to the wiring diagram on the unit for the
most up-to-date wiring.
The required wires are data lines 1 and 2 for communication, “R” (24 V AC power) and “C”
(24 V AC common) for power supply. For single-stage furnaces, connect “G”, “W1”, and
“YLO” on the terminal interface adapter. (See WIRING DIAGRAM for external relay wiring).
For two-stage furnaces, connect “W1”, “W2”, “YLO/Y1”, “Y/Y2” to the same terminal in the
interface adapter, and change switch on “DS2” according to the wiring diagram.

DEHUMIDIFICATION SETTING
The dehumidication performance will be improved by changing the
setting in Daikin
One + Smart Thermostat to “A” or “B” or “C”. Accordingly,
the minimum compressor speed will be locked due to different setting.
For example, by selecting “C” the minimum compressor speed will be
xed at 100% dehumidication capability. This operating range limitation
will be unlocked when the humidity reaches the set value.
The default setting is “B”. Please select the proper setting due to your
dehumidication demand or local climate. The setting can be changed
from the dehumidication setting menu at any time when required. For
instance, if “B” is still not adequate, you can select “C” to achieve the
maximum dehumidication performance.

TROUBLESHOOTING
As shown in wiring diagram, different LED lights show different status or
errors. H1P indicates network traffic, H2P shows network status and HAP
brinks means CPU is working.
The following fault code will be displayed on the thermostat. Also, the
STATUS LED [H2P] on the circuit board blinks. Repair according to the
details of the error.
