Your Daikin air conditioner manual explains every button, and this guide gives you the short version. Two things send people looking for a Daikin manual. Either the remote has a button nobody recognises, or the wall controller on a ducted system is showing something the installer never explained.
The manual itself is usually findable in a minute once you know where the model number is printed. What takes longer is working out what the controller actually does, because Daikin splits its controls across a handheld remote on wall mounted splits and a wired wall controller on ducted systems, and the two work differently.
This guide covers both, using the figures and procedures Daikin publishes for the Australian range.
Finding the right Daikin manual for your unit
Where the model number is printed
Every instruction below varies slightly by model, so start here. On a wall mounted split the model number is on a label on the side or underside of the indoor unit, and again on the outdoor unit. On a ducted system it is on the indoor chassis in the ceiling space, which is usually easier to read from the outdoor unit instead.
Daikin Australia publishes its operation manuals by model on its own website, so the model number is the only thing you need.
The remote model number is a separate thing
This trips people up. The remote has its own model number, printed on the back or inside the battery compartment, and it is not the same as the air conditioner model.
Daikin Australia manuals name several. The Cora range uses ARC466A26 on heat pump models and ARC466A27 on cooling only models, and the 50 to 71 class uses ARC466A28 or ARC466A29. The XL range uses ARC466A16 on reverse cycle models and ARC466A14 on cooling only models. The bulkhead ducted range uses ARC433A103.
Worth noting that the Australian Zena manuals do not state a remote model number at all, so if you own a Zena you will be matching by the air conditioner model rather than the remote.
Setting the clock on a Daikin remote
Do this first, because the timers will not behave without it. Daikin publishes five steps, and the order is worth noticing because Daikin sets the day before the time.
- Press the clock button.
- Use the select buttons to set the day of the week.
- Press the clock button again.
- Use the select buttons to set the time.
- Press the clock button to confirm.
On the Zena range the same sequence is described by what blinks. The day of the week blinks first, you adjust it and confirm, then the time blinks and you do the same.
The Daikin timers
On timer and off timer
Press the off timer or on timer button to start. The timer icon appears on the display and the timer lamp on the indoor unit lights up.
Use the up and down buttons to change the time. Daikin publishes an increment of ten minutes per press. Press the button again to confirm.
To cancel, press the timer cancel button. The icons disappear from the display and the timer lamp on the indoor unit goes out, which is a useful confirmation that you have actually cleared it rather than changed it.
The weekly timer
Daikin publishes up to four timer settings for each day of the week, which is twenty eight across a week. This is confirmed across the Cora, XL and Zena ranges.
Setting one runs in this order. Press the weekly button, select the day and the program number, choose whether it is an on or an off setting, set the time, set the temperature, then confirm.
As with the on and off timers, each weekly setting carries its own temperature, so the schedule can change how the room feels rather than simply switching the unit on and off.
Turning the schedule off without losing it
Two different things here, and people mix them up.
To deactivate the weekly timer while keeping every setting, press select while the word weekly is showing on the display. The schedule stays stored and stops running.
To erase the lot, hold the button for about five seconds while on the default display. Daikin is explicit that the result is that all reservations will be deleted. There is no undo.
Choosing a mode
The Daikin mode button cycles automatic, drying, cooling, heating, then fan only. That order is consistent across the Australian range.
If a symbol rather than a button is the puzzle, our guide to Daikin air conditioner symbols covers the display.
The temperature range Daikin publishes
Unlike some brands, Daikin states this plainly and the same figures appear in every Australian manual checked, including the wired controller used on ducted systems.
| Mode | Setting range | Note |
|---|---|---|
| Cooling | 18 to 32 degrees | The same on splits and on the ducted wired controller |
| Heating | 10 to 30 degrees | The low end is a frost protection setting rather than a comfort one |
| Automatic | 18 to 30 degrees | Narrower at both ends than cooling |
| Drying | No temperature setting | The unit works from the room temperature instead |
| Fan only | No temperature setting | Nothing is being conditioned |
If your remote refuses to go below 18 in cooling, nothing is broken. That is the published limit.
Airflow rate, which Daikin does not call fan speed
Daikin uses the term airflow rate, and publishes seven settings rather than the three or four people expect.
There is automatic, a dedicated indoor unit quiet setting, and then five manual levels running from low to high.
The indoor unit quiet setting is the one worth knowing about for bedrooms, because it is a separate setting rather than simply the lowest of the five.
Airflow direction and 3D airflow
Daikin controls up and down movement through the flaps and left and right movement through the louvres, and both can swing automatically.
The setting worth knowing is 3D airflow, where the flaps and louvres move in turn. That is aimed at larger or awkwardly shaped rooms where a fixed direction always leaves one corner behind.
You can also fix the direction in one position rather than swinging, which suits a room where the unit sits above a seat.
The named Daikin functions and what each one does
Powerful
Runs the system hard to shift a room quickly. Daikin publishes a duration of twenty minutes, after which operation returns to the previously set mode. It is a burst setting, not a way to run the system.
Econo
This is not simply a lower temperature. Daikin describes econo as limiting maximum power consumption so other appliances can run at the same time, and does it by limiting compressor rotation speed.
That makes it genuinely useful in a home where the air conditioner and an oven or a kettle share a circuit.
Comfort airflow
The airflow direction is upward in cooling and downward in heating, and the airflow rate is set to automatic while it runs.
The point is to avoid blowing directly at people while still conditioning the room properly. If somebody in the house complains about the draught rather than the temperature, this is the button.
Outdoor unit quiet
Reduces noise from the outdoor unit by changing the frequency and the fan speed, or as the Zena manual puts it, by limiting compressor speed.
Worth knowing if your outdoor unit sits near a neighbour boundary or under a bedroom window.
Intelligent eye
A motion sensor with a published behaviour. Daikin states that if no one is in the room for more than twenty minutes, operation automatically changes to energy saving operation.
It also detects movement and adjusts airflow direction and temperature to avoid direct contact with people. The lamp for it on the indoor unit is green.
Streamer
On models fitted with it, Daikin describes streamer as generating a high speed electron stream with high oxidising power, used to break down odours and airborne contaminants.
The wired wall controller on a ducted Daikin
If your Daikin is ducted, the wall controller is the whole interface and it works quite differently from a handheld remote. The controller Daikin Australia lists is the BRC073A4.
What the main screen shows
Daikin publishes eleven items on the basic screen. Operation mode, fan speed, airflow direction, the set or setback temperature, an error indicator, timer enabled, under centralised control, setback, the clock, detailed selection, and a timer problem indicator.
Two of those are worth understanding before you start pressing things. Under centralised control means the system is being managed from elsewhere and your local changes are blocked, which is common in apartments and offices. Setback means the controller is holding a background temperature rather than the one you set.
Changing mode, temperature and fan speed
Press the operation mode selector to cycle through cool, heat, fan, dry and auto. Daikin notes that operation modes which cannot be set on your system are simply not displayed, so a missing mode is usually a configuration rather than a fault.
The temperature moves one degree per press of the up or down button, within the ranges in the table above.
Fan speed on this controller has six steps. High, medium high, auto, medium, low and medium low.
Reaching the menu
Press the menu and enter button to open the main menu. Daikin publishes six items. Airflow direction, energy saving options, schedule, maintenance information, configuration, and current settings.
The key lock, and how to get out of it
This is a common reason a ducted controller appears dead. Press the menu and enter button for at least four seconds while the backlight is lit to lock the keys, and do exactly the same to release it.
If the screen is telling you the buttons are locked, that is the fix, and it takes four seconds.
Setting a schedule
The wired controller is more capable than the handheld here. Daikin publishes up to three different schedules, with a maximum of five actions per day, across all days of the week.
When an error appears
If an error occurs, the error icon on the basic screen and the operation lamp both blink. Pressing through takes you to a screen where the error code blinks alongside a contact address.
Write the code down before doing anything else. Our guide to Daikin error codes covers what the families mean, and the how to reset a Daikin guide covers what to try first.
One honest gap. The Australian BRC073A4 manual contains no filter sign or filter reset procedure. Other Daikin wired controllers sold in other markets do publish one, reached through the menu. If your controller is showing a filter message and there is no reset item in the menu, that is worth asking your installer about rather than assuming you have missed it.
Running the unit without a remote
On a wall mounted split there is a small on and off switch on the indoor unit. Press it once to start and once again to stop.
The settings are fixed. On a reverse cycle Daikin it starts in automatic mode at 25 degrees with automatic airflow. On a cooling only model it starts in cooling at 22 degrees with automatic airflow. You cannot adjust the temperature from the unit.
For ducted systems, Daikin does not publish a consumer emergency operation procedure. If your wall controller has failed there is no documented way to run the system without it, and that is a call to your installer rather than something to work around.
If the remote is the problem rather than the unit, our guide on a Daikin remote not working covers the batteries, the range and the interference sources Daikin names.
Common questions about Daikin remotes and manuals
Where can I download my Daikin manual?
Daikin Australia publishes operation manuals by model on its own site. Find the model number on the indoor or outdoor unit first, because the manuals are indexed by it rather than by the range name you bought it under.
Is there a reset button on the Daikin remote?
No. Daikin publishes no reset button on the handheld remote anywhere in the Australian range. The button often mistaken for one is cancel, which Daikin describes as diagnosing faults and returning to the default screen.
Why will my Daikin not go below 18 degrees in cooling?
Because 18 is the published lower limit in cooling. The limits are 18 to 32 in cooling, 10 to 30 in heating and 18 to 30 in automatic.
My ducted controller has stopped responding to any button
Check the key lock first. Hold the menu and enter button for four seconds while the backlight is lit. If the screen says buttons are locked, that is exactly what has happened.
Can I use a handheld remote and a wall controller on the same system?
Daikin advises against using both at the same time, because the wireless unit can display an incorrect status and settings get overwritten whenever either device is used. Pick one and use it consistently.
Where to start
Set the clock, then build one weekly schedule for the room you use most. Learn where econo and comfort airflow are, because those two change how the system feels and what it costs without you thinking about it again.
And find your model number once and write it somewhere, because every manual, every part and every service call starts with it.
If the controller is doing something the manual does not explain, our Daikin air conditioning service covers split and ducted systems across Melbourne, and you can request a quote first.
