Daikin Madoka

A wired controller fixed to the wall and linked to your indoor unit. It has a round screen with a light around it and four buttons underneath.

It comes in white, silver or black. They all work the same way.

Two ways to use it

Buttons or your phone

Everything day to day is on the four buttons. The free Madoka Assistant app adds schedules, a holiday setting and energy use.

Not every option shows on every system. If something in this guide is missing, your indoor unit doesn't have it.

01

The basics

Four buttons do everything.

STEP 1

The four buttons

  • ON/OFF (the power symbol): switches the air conditioning on and off.
  • Tick (ENTER): opens the menu and confirms what you've picked.
  • Left and right arrows: move through the menu and change numbers. Left lowers, right raises.

If the screen has gone blank, press any button to wake it up.

STEP 2

Switch on and off

Press ON/OFF. The light around the screen comes on while it runs. Press it again to switch off.

The fan can run on for a short while after you switch off from heating. That's normal: it's clearing warm air out of the unit.

STEP 3

Set the temperature

On the home screen, press the right arrow to go warmer or the left arrow to go cooler. It moves 1°C at a time, from 16 to 32°C.

The number is the temperature you've asked for, not the room temperature. Most people are comfortable at 20 to 22°C for heating and 23 to 25°C for cooling.

Can't go past a certain number? Your installer may have set limits to save energy.
STEP 4

The home screen

Your installer sets one of two layouts:

  • Standard: the temperature you've set and the mode.
  • Detailed: the same, plus the symbols in Part 04 and, on some systems, the room temperature.

To save power the screen and light dim when nobody has pressed a button for a while.

03

The phone app

Madoka Assistant, free on iPhone and Android. It talks to the controller by Bluetooth, so stand close by.

STEP 10

Connect your phone

  1. Download Madoka Assistant from the App Store or Google Play.
  2. On the controller, open Bluetooth in the menu and turn it on.
  3. In the app, tap your controller and accept.
  4. Check the number on your phone matches the controller, then press the tick on the controller to accept.
STEP 11

Schedules and saving energy

  • Schedule: up to 5 changes a day, such as warm by 7am and off at 9am. You can save 3 schedules and use one at a time.
  • Holiday: pauses your schedule while you're away.
  • Off timer: switches off after a set time.
  • Energy use: see how much electricity it has used.

A clock symbol on the home screen means a schedule or the off timer is running. Some settings, such as setback, are set up by your installer.

04

What the symbols mean

Shown on the detailed home screen. Daikin's symbols are drawn simply here, so yours may look a little different.

Running

The air conditioning is switched on.

Off

The air conditioning is switched off.

Defrost or warm-up

The fan has stopped while the unit defrosts or warms up. Normal, it carries on by itself.

Schedule or timer

A schedule or the off timer is running.

Filter

The filters need cleaning. See step 13.

Warning

Something needs attention or maintenance. See step 14.

Information

A message is waiting for you.

Bluetooth

The controller is talking to the Madoka Assistant app.

Lock

That setting has been locked and can't be changed.

Central control

A central controller in the building limits what you can change here.

Heating or cooling set elsewhere

Another unit or controller decides heating or cooling. See Part 05.

Setback

While it's off, the unit keeps the room from getting too hot or too cold.

05

Several controllers in one room

In a big open space you may have more than one indoor unit, each with its own Madoka.

STEP 12

Keep them in step

  • Set them all to the same temperature, or within a degree. If one asks for 18°C and another 24°C, they work against each other and waste energy.
  • One controller decides heating or cooling. The others follow it. If you try to change the mode on one of those, the mode symbol blinks and it won't change.
  • To switch between heating and cooling, use the controller your installer set as the one that decides.
06

If something's not right

Most things have a simple answer.

STEP 13

Filter sign

A filter symbol on the home screen, or a Time to clean filter message, means the filters need cleaning.

Clean them as your indoor unit's manual shows, then press the tick to clear the sign. Your yearly service includes a full clean if you'd rather leave it to the engineer.

STEP 14

An error or warning

If the light blinks or a warning symbol shows, press the tick to see the message and its code, such as U4.

Write down the code and which room it's in, then contact your installer. The code tells the engineer what the unit needs, so please don't keep switching it off and on.

STEP 15

The leak alarm

Newer systems use the Madoka as a refrigerant leak alarm. If it buzzes, the light flashes and the screen shows a code starting A0:

  1. Hold the tick for 3 seconds to stop the alarm, or stop it in the app.
  2. Air the room and keep naked flames away.
  3. Contact your installer.
More than one controller? Each alarm has to be stopped on its own controller.

It isn't doing anything

  • Press any button: the screen may just have gone to sleep.
  • Check the temperature you've set. In heating it must be above the room temperature, in cooling below it.
  • Check a schedule or the off timer hasn't switched it off.

Heating has gone quiet for a few minutes

  • In cold, damp weather the outdoor unit defrosts. The fan stops and the defrost symbol shows for about 6 to 8 minutes, then it carries on.
  • After switching on, it waits a few minutes before blowing so it doesn't blow cold air at you.
  • Neither needs a call out.

Quick reminders

Tick them off as you try each one. Nothing here is saved or sent.
