Wiring Requirements
The Daikin ENVi thermostat uses 4-wire low-voltage cable to
connect to the Daikin Power and Communication Adapter
(DPCA) which in turn connects to the Indoor Unit.
The maximum wire length between the Daikin ENVi thermostat
and the DPCA is as follows:
18 AWG: 1250 ft/380 m
20 AWG: 800 ft/240 m
22 AWG: 500 ft/150 m
INSTALLING THE THERMOSTAT KIT
There are 5 steps to install the Daikin ENVi thermostat kit:
Step 1. Power O the Daikin Indoor Unit
Step 2. Position and Wire the DPCA
Step 3. Install the Daikin ENVi thermostat
Step 4. Connect the Thermostat Wiring
Step 5. Mount the DPCA
Step 6. Power On Daikin Indoor Unit
Step 1. Power O the Daikin Indoor Unit
Before installing the Daikin ENVi thermostat kit, disconnect the
power to the Indoor Unit.
WARNING: The Indoor Unit uses a high-voltage 208/230V
power source. Always DISCONNECT power to the Indoor Unit
before connecting any power wires. Failure to do can result in
death, re, or electrical shock.
7

Step 2. Position and Wire the DPCA
The Daikin Power and Communication Adapter (DPCA) provides
an interface between the thermostat and Indoor Unit.
To install the DPCA:
1. Position the DPCA in a suitable location, away from water
and near the Indoor Unit (for example, a backside cavity of
a wall-mounted unit). The DPCA is not plenum rated and
should be mounted in a non-plenum space.
2. Connect the DPCA power cable to the Indoor Unit power
supply terminals. Ensure that the electrical connections are
securely tightened.
3. Remove the DPCA cover by grasping both sides and pulling
along the length of the DPCA.
4. Use the Wiring Harness to connect the P2 terminal
on the DPCA to the S21 terminal on the Indoor Unit’s
main PCB. Refer to the Daikin system installation
manual for information about accessing the S21
terminal.

an interface between the thermostat and Indoor Unit.
To install the DPCA:
1. Position the DPCA in a suitable location, away from water
and near the Indoor Unit (for example, a backside cavity of
a wall-mounted unit). The DPCA is not plenum rated and
should be mounted in a non-plenum space.
2. Connect the DPCA power cable to the Indoor Unit power
supply terminals. Ensure that the electrical connections are
securely tightened.
3. Remove the DPCA cover by grasping both sides and pulling

Step 3. Install the Daikin ENVi Thermostat
The ideal location for the thermostat is approximately 5 ft (1.5 m)
above oor level in the main living area.
Do not install the thermostat:
Close to sources of heat such as incandescent lights
Near supply heating/cooling sources
In direct sunlight
On exterior, non-insulated or poorly insulated walls
In the kitchen or other areas of potentially high heat and/or
humidity
In an area that could restrict air ow
To install the thermostat:
1. If necessary, remove the previous thermostat.
1. Gently separate the backplate from the Daikin ENVi
thermostat.
2. Place the thermostat backplate on the wall. Make sure that
any existing wires can be inserted through the opening for
the wiring.
If the backplate does not adequately cover the area where
the previous thermostat was installed, attach the trim plate
to the back of the backplate to increase its coverage.
3. Using the backplate as a template, mark the location of the
mounting holes on the wall as shown.
10

4. Move the backplate out of the way and make holes where
indicated in the previous step. The mounting holes can
accommodate a #6 pan-head screw. It is recommended to
use the included fasteners to ensure proper tting of the
front housing.
5. Use the included drywall plugs (or other suitable anchors) to
ensure the thermostat can be mounted securely to the wall.
6. Fasten the backplate and optional trim plate to the wall
using the screws provided (or other suitable screws).

Step 4. Connect the Thermostat
Wiring
Use the eld-supplied 4-wire low-voltage cable
to connect the thermostat to the DPCA.
To connect the thermostat to the DPCA:
1. Connect the wires as shown:
2. Attach the Daikin ENVi thermostat to the
backplate. Ensure that the pins on the
thermostat align with the terminal block on
the backplate.

Step 5. Mount the DPCA
After you make the necessary wiring
connections, mount the DPCA by using the
adhesive sticker or mounting screws as needed.
Step 6. Power On Daikin Indoor
Unit
After you’ve completed the wiring, you can
apply power to the Daikin Indoor Unit. The
Daikin ENVi thermostat receives power from the
equipment and will automatically power on.
After you power on the Indoor Unit:
1. Verify the green LED on the DPCA has turned
on. Upon verication, re-attach the DPCA
cover.
2. Use the wire ties to secure the wires as
needed.

CONFIGURING THE DAIKIN
ENVi THERMOSTAT
The rst step after installing the Daikin ENVi
thermostat is to congure the thermostat
settings for the Indoor Unit.
Preferences
This section describes the user preferences that
should be congured during installation. For a
complete description of all user preferences, see
the Daikin ENVi User Manual.
Intelligent Eye
Some models of the Indoor Unit include an
intelligent eye, an infrared sensor that detects
room occupancy. It adjust the set point by 3.6°F
(2°C) if no movement is detected in order to
save energy (+3.6°F/+2°C if cooling, –3.6°F/–2°C
if heating).
To use intelligent eye, you must enable this
option in the Daikin ENVi thermostat and
then enable it with the Daikin wireless remote
controller. If enabled, the thermostat’s Smart
Recovery and Temp Alert functions are not
available.
By default, intelligent eye is disabled on the
thermostat.
Do NOT enable the intelligent eye with the Daikin
wireless remote controller when it is disabled on
the thermostat as this may cause suboptimal
operation and result in invalid recovery and alert
messages. Also, if an auxiliary heater is congured,
enabling intelligent eye may energize the auxiliary
heater more often than would normally be
required.
To congure the
intelligent eye:
From the Home screen,
press MENU.
Select Settings ▶
Preferences.
Select Intelligent Eye.
Enable (Yes) or disable
(No) the intelligent eye
sensor.
