1.1 For the user
INFORMATION
Also see the operation manual delivered with the outdoor
and indoor unit.
WARNING
Do NOT play with the unit or its remote controller.
Accidental operation by a child may result in impairment of
bodily functions and harm health.
WARNING
To prevent electric shocks or fire:
▪ Do NOT operate the controller with wet hands.
▪ Do NOT disassemble the controller and touch interior
parts. Contact your dealer.
▪ Do NOT modify or repair the controller. Contact your
dealer.
▪ Do NOT relocate or reinstall the controller by yourself.
Contact your dealer.
NOTICE
To clean the controller, do NOT use organic solvents, such
as paint thinner. Possible consequence: damage, electric
shock, or fire.
1.2 For the installer
The precautions described in this document cover very important
topics, follow them carefully.
INFORMATION
This controller is an option and cannot be used standalone.
Also see the installation and operation manual of the
indoor and outdoor units.
NOTICE
Improper installation or attachment of equipment or
accessories could result in electric shock, short-circuit,
leaks, fire or other damage to the equipment. Only use
accessories, optional equipment and spare parts made or
approved by Daikin.
WARNING
All field wiring and components MUST be installed by a
licensed electrician and MUST comply with the applicable
legislation.
NOTICE
The remote controller MUST be mounted indoors.
NOTICE
When the controller is used as room thermostat, select an
installation location where the average temperature in the
room can be detected.
Do NOT install the controller in the following places:
▪ In places that are exposed to direct sunlight.
▪ In places that are near a heat source.
▪ In places that are affected by outside air or air draught due to e.g.
door opening/closing.
▪ In places where the display can easily get dirty.
▪ In places where there is NO easy access to the controls.
▪ In places with temperatures <–10°C and >50°C.

6 Operation
INFORMATION
Depending on the indoor unit, more or less operation
modes are available.
6.1.1 About the operation modes
INFORMATION
If the indoor unit is a cooling-only model, it can only be set
to run in Cooling, Fan only, or Dry operation mode.
INFORMATION
If the operation mode changeover of an indoor unit is
under centralised control ('changeover under centralised
control' status icon blinking in the home screen), then it is
NOT possible to change the operation mode of that indoor
unit. For more information, see "Switch Cooling/Heating
master"on page26.
Cooling
If the outdoor air temperature is high, it can take some time until the
indoor room temperature reaches the setpoint temperature.
When the indoor room temperature is low, and the indoor unit is set
to run in Cooling operation mode, the indoor unit can enter Defrost
operation mode first (i.e. Heating operation), this to prevent a
decrease of the system's cooling capacity due to frost on the heat
exchanger. For more information, see "Heating"on page6.
The indoor unit can run in Cooling operation mode because it is
operating under Setback conditions. For more information, see
"15.5.11Setback"on page30.
Heating
When running in Heating operation mode, the system requires a
longer time to reach the setpoint temperature than when running in
Cooling operation mode. To make up for this, it is recommended to
let the system start operation in advance by making use of the timer
function.
The indoor unit can run in Heating operation mode because it is
operating under Setback conditions. For more information, see
"15.5.11Setback"on page30.
To prevent cold drafts and a reduction of the system's heating
capacity, the system can run in the following special heating
operation modes:
INFORMATION
When the system is stopped while the indoor unit is
running in Heating operation mode, the fan will continue to
operate for approximately 1minute, this to get out any heat
remaining in the indoor unit.
INFORMATION
▪ The lower the outdoor air temperature, the lower the
heating capacity. If the system's heating capacity is
insufficient, it is recommended to include another
heating appliance into the setup (if you use a
combustion appliance, ventilate the room regularly.
Also, do not use the heating appliance in places where
it is exposed to the airflow of the indoor unit).
▪ The indoor unit is of the hot air circulation type. As a
result, after operation start, it takes the indoor unit
some time to warm up the room.
▪ The indoor unit fan will automatically operate until the
indoor temperature of the system rises to a certain
level.
▪ When hot air stays under the ceiling and your feet feel
cold, it is recommended to include a circulator into the
setup.
Dry
NOTICE
To prevent water leakage or system failure, do NOT turn
off the system immediately after indoor unit operation.
Before turning off the system, wait until the drain pump
finishes discharging any water remaining in the indoor unit
(approximately 1minute).
INFORMATION
To ensure a smooth start, do not turn off the system while
it is operating.
6.1.2 To set the operation mode
1 Navigate to the operation mode menu.
Operation Description
Defrost To prevent the loss of heating
capacity due to frost
accumulation in the outdoor unit,
the system will automatically
switch to defrost operation.
During defrost operation, the
indoor unit fan will stop
operation, and the following icon
will appear on the home screen:
The system will resume normal
operation after approximately 6
to 8 minutes.
Hot start (VRV only) During hot start, the indoor unit
fan will stop operation, and the
following icon will appear on the
home screen:

Slave
For more information, see "13.4.1Information screen"on page13.
INFORMATION
It is only possible to use a master and a slave controller of
the same type.
INFORMATION
In case digital input adapter BRP7A5* is part of the
system, it is not possible to connect and designate a
second controller. Connecting a second controller when
the system already contains the adapter, will cause the
adapter to go in error.
INFORMATION
If a slave controller does not display the home screen 2
minutes after its designation, turn off the power and check
the wiring.
INFORMATION
After re-designating a controller, the system requires a
power reset.
12 Starting up the system
CAUTION
Before starting up the system, make sure:
▪ The indoor and outdoor unit wiring is completed.
▪ The switch box covers of the indoor and outdoor units
are closed.
The controller gets its power from the indoor unit. It will start up as
soon as it is connected. For the controller to be operable, therefore
make sure the indoor unit is powered on.
Once the controller is powered, it will automatically start up. If it is
the first and only controller that is connected to the indoor unit, it will
automatically get designated as master controller. For a second
controller to get designated as slave controller, manual action is
required. For instructions, see "12.2 To designate a controller as
slave"on page12.
12.1 Master and slave controller
INFORMATION
The following functions are not available for slave
controllers:
▪ "Auto" operation mode
▪ Individual airflow direction

12.2 To designate a controller as slave
Prerequisite: A master controller is already connected to the indoor
unit.
