Frequently Asked Questions - BRC1H519K DAIKIN

How do I pair the remote control with my Daikin air conditioner?

No pairing is required. The remote control uses infrared signals and works out of the box with compatible Daikin units. Ensure no obstacles block the signal and point the remote directly at the indoor unit.

What type of batteries does the remote use?

It uses two AAA alkaline batteries (1.5V). Do not use rechargeable batteries as they have lower voltage and may cause erratic operation.

How do I replace the batteries?

Slide the battery cover on the back of the remote downward to open. Remove old batteries and insert new ones matching the polarity (+/-) indicated inside the compartment. Close the cover.

The remote display is dim or not showing anything. What should I do?

First, replace the batteries with fresh ones. If the display still does not work, check for any physical damage or moisture. If the issue persists, the remote may need replacement.

What is the operating range of the remote control?

The effective range is up to 8 meters in a direct line of sight. The signal may be reduced if there are obstacles like walls or furniture.

Can I use this remote with any Daikin air conditioner?

This remote is designed for select Daikin split-type air conditioners. Check your indoor unit's manual for compatibility or look for the same model number on your original remote.

How do I clean the remote control?

Use a soft, dry cloth to wipe the surface. Do not use water, solvents, or abrasive cleaners, as they may damage the remote.

The remote does not work after battery replacement. What could be wrong?

Ensure batteries are inserted correctly (polarity). Check if the battery contacts are clean and not bent. Also verify that no buttons are stuck. If it still does not work, the IR emitter may be faulty.

Is there a reset button on the remote?

No dedicated reset button exists. To reset, remove batteries, wait 30 seconds, and reinsert them. This clears any temporary glitches.

What do I do if the remote control is lost or broken?

You can purchase a replacement remote (model BRC1H519K) from Daikin dealers or online stores. Some universal remotes are also compatible but may lack full functionality.

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 page 26.

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 page 6.

The indoor unit can run in Cooling operation mode because it is operating under Setback conditions. For more information, see "15.5.11 Setback" on page 30.

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 "15.5.11 Setback" on page 30.

To prevent cold drafts and a reduction of the system's heating capacity, the system can run in the following special heating operation modes:

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:

INFORMATION

When the system is stopped while the indoor unit is running in Heating operation mode, the fan will continue to operate for approximately 1 minute, 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

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 page 12.

14.1.4 Field settings

About field settings

The controller allows for making field settings related to the indoor unit, and to the controller itself.

Screen Field settings
	Indoor unit
	Remote controller

In both case, the setting procedure is the same. For instructions, see "Setting procedure" on page 15.

Setting procedure

Field settings are composed of the following components:

1 Modes ("Mode"),
2 Units ("Unit"),
3 Settings ("SW"), and
4 Values for those settings.

The field settings menus have two levels. You set modes and units in the first level, and settings and values in the second.

14 Configuration

Level Description

First level Mode (Mode)

A mode is a group of settable parameters.

In the field settings tables, find available mode numbers in the "Mode" column. Mode numbers that apply to individual indoor units are between brackets in the "Mode" column.

Unit (Unit) (indoor unit field settings only)

A unit is an individual unit to which a setting might apply.

When making field settings for individual units, this is the place where you define the number of the unit to which the setting applies.

When making field settings for grouped units, you do NOT set the unit number. The settings will then apply to all indoor units that are part of that group.

Second level Setting (SW)

A setting is a settable parameter. These are the settings you are making.

In the field settings tables, find the available setting numbers in the "SW" column.

Value

A value is one of a fixed set of values that you can choose for a setting.

When the value field contains a "-" , there are no values available for the selected setting:

When making group settings, you can ONLY set a value for a setting if the value field contains a "*" (if the value field does NOT contain a "*", you cannot apply the selected setting to the group):

In the field settings tables, find the available values for each setting in the "Value" column.

Navigation

1 Use

ve the highlighter.

To navigate through the field settings menus, use

2 Press to select a field setting component.

3 Use a to change the value of that field setting component.

4 Press to confirm that value.

5 In the first level, select to move to the second level.

6 In the second level, navigate and select in the same way as you did in the first level.

7 Select to confirm and activate made settings.

8 At all times, select to go back a level.

Indoor unit field settings

The setting procedure is different depending on whether you want to make settings for individual units, or for grouped units.

Individual indoor units

• Define a mode by setting a Mode number (number between brackets)
• Define the unit to which the setting will apply by setting a Unit number
• Define the setting by setting a SW number

- Define a value for that setting

Grouped indoor units

• Define a mode by setting a Mode number (number NOT between brackets)
• Do NOT set a Unit number (setting applies to all the units in the group)
• Define the setting by setting a SW number
• Define a value for that setting

External input interlock

About external input interlock

External input interlock allows for the integration of key card and window contact logic into the system.

External input interlock is only available in case digital input adapter BRP7A5* is part of the system. When the adapter is part of the system:

• it is not possible to connect a second (slave) controller, and
• the schedule function will be disabled for as long the adapter is connected to the indoor unit.

Make sure that the digital input adapter and its optional contacts (window contact B1 and key card contact B2) are correctly installed. Confirm that the voltage free contact of the digital input adapter is in the correct position. For instructions on how to install the digital input adapter, see the installation manual of the digital input adapter. In case the digital input adapter does not function properly, the external input interlock menu is not available in the installer menu. In case a centralised controller is additionally part of the system, external input interlock is controlled by the centralised controller. The digital input adapter is then overruled.

INFORMATION

• The "previous state" can be the on/off state, operation mode, cooling setpoint, and heating setpoint.
• When using the contacts, the fan speed as well as the Setback cooling and heating setpoints can be changed at any time, without losing changes.
• The fan speed is stored independently for the two main operation modes (Heating and Cooling). Separate fan speed settings are saved for Heating operation mode on the one hand, and Cooling, Dry and Fan only operation mode on the other hand.
• When closing the contact, changes made while the key card contact is open and the delay timer has not expired (normal operation) will not be saved.

Combination of window contact and key card contact logic

• The window contact has priority over the delay timer and the Setback functionality of the key card contact: When the window contact is opened while the key card contact is open, the delay timer will immediately expire if it is still running, and Setback will not work anymore. The reset timer will immediately start counting or will not reset when it was already running.
• The reset timer functionality of the key card contact has priority over the window contact when returning to the previous state: When the key card contact is opened while the window contact is open, the delay timer will start running. When the delay timer expires the reset timer will start running. When the reset timer expires, the previous state is updated to the "Default Reset Setting" state.

Example 1

1 You remove the key card.
Result: The indoor unit continues operating normally until the delay timer expires.
2 You open the window before the delay timer expires.

Result: The indoor unit stops immediately. It is not possible to turn the unit on or off, the Setback functionality does not work, the delay timer stops counting, and the reset timer starts counting.

3 You insert the key card again.

Result: An update of the previous state occurs. The unit is forced off and the Setback functionality is still disabled (see "Window contact logic" on page 24).

IF the reset timer HAS NOT expired before inserting the key card, the previous state is the same as the original state because there was only a change to the original state.

IF the reset timer HAS expired before inserting the key card, the previous state is the "Default Reset Setting" state.

4 You close the window.

Result: The unit reverts to the previous state. The previous state depends on the expiration of the reset timer.

Example 2

1 You open the window.
Result: The unit stops immediately. It is not possible to turn the unit on or off with the ON/OFF button, the Setback functionality does not work, and the delay timer does not start counting.
2 You remove the key card.
Result: The delay timer starts counting.
3 You close the window again.
Result: There is no change in state. It is as if you never opened the window (Setback will work if enabled).
IF the delay timer HAS expired before closing the window, the reset timer will have started counting. Closing the window has no influence on the reset timer.
IF the delay timer HAS NOT expired before closing the window, it will expire immediately and the reset timer will start counting. When the reset timer expires, the previous state is updated to the "Default Reset Setting" state.

4 You insert the key card again.

Result:

IF the reset timer HAS NOT expired before inserting the key card, the unit returns to the state before the window was opened (last "on" state);

IF the reset timer HAS expired before inserting the key card, the unit goes to the "Default Reset Setting" state.

When multiple indoor units are connected to the same outdoor unit, there are restrictions as to the operation modes in which they can run. One outdoor unit does not allow for one indoor unit to perform Cooling operation, while another performs Heating operation.

Therefore, the system requires that one indoor unit is set as cooling/heating master. This indoor unit then decides the operation modes in which the other (slave) indoor units can run. When one indoor unit is set as cooling/heating master, the other indoor units automatically become its slaves. For instructions, see "To set Cooling/Heating masterhood" on page 26.

Cooling/Heating masterhood corresponds to the following status icon:

The behaviour of this status icon is according to the following table:

If a controller displays ... Then ...
... NO status icon ... The indoor unit connected to that controller is Cooling/Heating master.
... a CONSTANT status icon ... The indoor unit connected to that controller is slave to a Cooling/Heating master.
... BLINKING status icon	... NO indoor unit is assigned as Cooling/Heating master yet.

The operation mode behaviour of the indoor units is according to the following table:

If the master ...	Then the slaves ...
... is set to "Heating", "Dry", or "Auto" operation mode	... start running in the same operation mode as the master. No other modes are then available for them.
... is set to "Cooling" operation mode	... then the slaves cannot run in "Heating" operation mode, but can still run in "Cooling", "Fan only" and "Dry" operation mode.
... is set to "Fan only" mode	... can ONLY run in "Fan only" mode.

Once an indoor unit is set as master, it can be released from masterhood. For instructions, see "To release Cooling/Heating masterhood" on page 27.

To set Cooling/Heating masterhood

15.5.22 Field settings

Make indoor unit and remote controller field settings. For an overview of possible field settings, see "Indoor unit field settings" on page 18 and "Remote controller field settings" on page 19.

Setting procedure

Field settings are composed of the following components:

• Modes
• Units
• Settings
• Values

The field settings procedure differs depending on whether you are making settings for individual indoor units or for groups of indoor units, or for the remote controller.

Field settings type Procedure
Individual indoor units • Set the field setting type to "Indoor unit".Define a mode. In the field settings table, find this number between brackets in the Mode column.Define the unit to which the setting will apply by setting a unit number.Define the setting by tapping the right tile in the app. In th field settings table, find settings in the SW column.Define a value for that setting.
Groups of indoor units	• Set the field setting type to "Indoor unit".Define a mode. In the field settings table, find this number NOT between brackets in the Mode column.Do NOT set a unit number (the settings will apply to all units in the group).Define the setting by tapping the right tile in the app. In th field settings table, find settings in the SW column.Define a value for that setting.
Remote controller	• Set the field setting type to "Remote controller".Define a mode.Define the setting by tapping the right tile in the app. In th field settings table, find settings in the SW column.Define a value for that setting.

Default values

Field setting default values are different depending on the indoor unit model. For more information, see the service manual of the indoor units. For the following field settings, the default values are the same for all indoor unit models:

Field setting Default value
Thermostat sensor 02
Setback 04
Window contact B1 02
Key card contact B2 02
Airflow direction range 02
Remote controller thermostat sensor	02
Rotation overlap time 03

INFORMATION

• The connection of optional accessories to the indoor unit might cause changes to some field settings. For more information, see the installation manual of the optional accessory.
• For details about the specific field settings of each type of indoor unit, see the installation manual of the indoor units.
• Outdoor unit field settings can only be configured via the outdoor unit PCB. For more information, see the installation manual of the outdoor unit.
• Field settings that are not available for a connected indoor unit are not displayed.

15.5.23 Duty rotation

Activate Duty rotation to let the indoor units operate alternately (one indoor unit alternately inactive), this to increase system lifespan and reliability.

Duty rotation is designed for units operating in critical applications (e.g. in server rooms that require lots of cooling). In these cases, the system is equipped with an extra backup unit. Activating Duty rotation then allows for:

• Rotation: because the system is equipped with more units than are required to provide the heating/cooling load, one of the units can remain inactive during normal operation. After a set time (i.e. "Rotation cycle time"), the inactive unit will start operation, and a previously active unit will become inactive (i.e. duty rotation). Because the units only operate alternately, the lifespan of the system increases.
• Backup: having a backup unit allows for system redundancy. If an active unit goes into error, "Duty rotation" makes sure an inactive one takes over.
