Features and Benefits
Designed with quality components
The high-resolution color touch screen display is protected
by the same toughened glass used in smart phones.
The anodized aluminum bezel and dial are precision manufactured.
The surfaces have a fine bead blast with a warm hued anodized
finish. The dial rotation is extraordinarily smooth because it rests on
a bearing assembly typically found in precision instruments.
A switch
behind the dial enables users to return to the home screen from
any menu with a single tap.
An integrated Wi-Fi radio connects to the internet (via a home
router) to the cloud and onto the homeowner mobile application.
The Daikin cloud will also seamlessly integrate with open smart
home architectures, including Amazon Alexa and Google Assistant,
enabling consumers to effortlessly use features such
as voice control.
A thin LED light bar sits flush within the bottom surface and runs
from edge to edge, delicately illuminating the wall beneath. Emitting
a soft emotive glow, the light bar indicates the current system mode:
red for heating, blue for cooling.
Built-in bubble level aids professional installation

Installing the Daikin One+ smart thermostat
» Mounting the thermostat will be leveled:
– Approximately 5’ from the floor.
– On an interior wall using the included screws.
Important Notes:
» You do not need the trim plate to mount the thermostat.
» Screws included are designed to mount in sheetrock or studs
» Its recommended to use the screws provided with
Daikin One+ packaging for best results
Use included screws

11
» Maximum wire distance between the Daikin One+ and the
indoor unit should not exceed 125 feet using 18-gauge wire .
» For installing the Daikin Fit outdoor system, it is strongly
recommended (for best results) to use 18-gauge wire.
» Check for proper voltage before and after wiring
is installed.
– 0.6 VDC between Data 1 and 2
– 24 VAC between common and power
» Wiring communicating indoor unit to communicating
outdoor units.
– Connect 1, 2, C and Rfrom the Daikin One+, to 1, 2, C
and Rat the indoor unit.
– Connect wires 1and 2from the indoor unit to 1and 2
at the outdoor unit.
» Wiring communicating indoor furnace unit to non-communicating
outdoor units.
– Connect 1, 2, C and Rfrom the Daikin One+, to 1, 2, C
and Rat the indoor furnace unit.
– Connect wire Y1 from the indoor furnace unit to Y1 at
the outdoor unit
– Under Equipment Setup add ‘24 VAC Condenser’.
– Under ‘24 VAC Condenser’ select the matching kBTU
from ‘cool CFM’ settings

INTRODUCTION
» The indoor furnace control is equipped with a dedicated
humidification relay which is available through ¼ inch
terminals HUM-IN and HUM-OUT
» HUM-IN must be powered with the desired voltage
(24 VAC from the R terminal or 115 VAC from L1 terminal)
» Humidification relay turns ON when there is call for heat
and a call for humidification
» For 2-stage furnace only, humidifier relay supports
below modes
– ON: Humidifier is turned on with a heat demand
and humidification demand
– OFF: Humidifier remains off (relay never closes).
How to Wire a Humidifier to Daikin Furnace

18
The following steps require no power to be applied.
– Check for any loose, disconnected, broken, or shorted wires
between all connected components BEFORE applying power
– No short between Data 1 or Data 2 wires and R (24 VAC) or C (24
VAC common)
– Check for Data 1 and Data 2 wires reversed at the indoor unit,
thermostat, or outdoor unit
After fixing all the wiring issues apply power
– Check for 24 VAC across R (24 VAC) and C (24 VAC common)
terminals
– If there are still problems discovering the indoor or outdoor
equipment then check for bias reading of 0.6 VDC. Bias reading
of 0.6 VDC indicates a robust network that can handle high data
volume without lock-up.
Wiring Troubleshooting
0.6 VDC
NOTES: If Bias reading is below 0.6 VDC, check the TERM Dip-Switch (DS1) setting
on the outdoor unit. Move the TERM Dip-Switch (DS1) to OFF Position. This
should improve the Bias reading to 0.6 VDC

19
– Follow the steps below to measure and achieve 0.6 VDC bias
value.
– Turn OFF the thermostat and make sure the system is idle
– Take Bias readings on the outdoor Heat Pump or Air Conditioner
– Measure DC voltage between 24 VAC common to Data 1 = D1 VDC
– Measure DC voltage between 24 VAC common and Data 2 = D2 VDC
– Bias reading = D1 VDC – D2 VDC (Subtract D2 from D1 to calculate bias voltage)
= 0.61 VDC
– Measure DC voltage between Data 1 and Data 2. This value should
equal the value calculated in the previous step.
– Take Bias readings on indoor Air Handler or Furnace by repeating
above steps on its terminal blocks.
– Take Bias readings on CAPE EEV coil if connected by repeating
above steps on its terminal blocks.
– The Bias readings should match on all the equipment's terminal
blocks.
– If Bias reading is below 0.6 VDC, check the TERM Dip-Switch (DS1)
setting on the outdoor unit. Move the TERM Dip-Switch (DS1) to
OFF position. This should improve the Bias reading to 0.6 VDC.
– After stabilizing the network, power down the entire HVAC
system. Wait for a few minutes and power back up. It will take
approximately 3-5 minutes for the HVAC system and thermostat to
discover the indoor and outdoor equipment.
