Mitsubishi air conditioner wifi control lets you run the unit from your phone. Most failed Mitsubishi Wi Fi setups come down to one thing, and it is not the air conditioner. The adaptor will only join a 2.4 GHz network, and a modern router hands out a 5 GHz one by default.
Once you know that, the rest of the process is short. This guide covers what you need, how to pair the unit, what the lights mean while you are doing it, and the handful of things Mitsubishi publishes that catch people out afterwards.
What you need before you start
Three things, and it is worth confirming all three before you touch a button.
A Wi Fi interface, or a unit with one built in
Older Mitsubishi Electric systems need an adaptor fitted to the indoor unit. The current one is the MAC 568IF E, which Mitsubishi states is compatible with M Series, P Series and CITY MULTI indoor units manufactured after January 2015. It connects to the control board inside the unit, so fitting it is a job for an authorised technician rather than a DIY task.
Several current ranges now ship with Wi Fi built in. Mitsubishi Electric Australia announced built in Wi Fi across the MSZ AP, MSZ EF and MFZ KW series, with one published exception, the MSZ AP20VGD2, which does not have it.
If you are unsure which you have, look at the model number on the indoor unit and compare it with the product page for your range. The built in Wi Fi models and the ones requiring the adaptor are listed separately.
A router on 2.4 GHz with the right encryption
This is the one that stops most people. Mitsubishi publishes two hard requirements.
- 2.4 GHz needs to be enabled on dual band routers. The adaptor does not join a 5 GHz network.
- The router must be capable of WPA2 PSK with AES encryption.
If your router broadcasts one combined network name across both bands, that usually works, but some routers need the 2.4 GHz band enabled or separated before the adaptor can see it. That setting lives in the router, not in the air conditioner.
The app
Mitsubishi Electric Australia publishes the app under slightly different names across its own pages. On the app stores it is listed as Mitsubishi Wi Fi Control. It is the Australian app. If you find something called MELCloud or kumo cloud, those are the European and North American apps and neither will work here.
Pairing the unit, two published methods
Mitsubishi publishes two ways to get the adaptor onto your network. Access point mode works with any router. WPS mode is quicker but only if your router supports it.
Access point mode
This is the method that works everywhere, and it is the one to use if WPS fails or your router does not have it.
- Download the app and create an account.
- Hold down the MODE button on the interface for 7 seconds. The MODE light starts flashing orange every 5 seconds.
- Read the network name from the label on the device, or scan the code on it where your model provides one.
- Connect your phone to that network, using the key printed on the same label.
- Open the app, follow the setup, and select your home Wi Fi network from the list.
- Enter the MAC address and ID from the label to add the unit to your account.
There is a time limit on this. Mitsubishi publishes ten minutes to complete setup in access point mode. If you stop halfway to find the router password, you may need to start again, so have it in hand before you begin.
WPS push button mode
Faster, if your router has a WPS button.
- Check the router has WPS enabled.
- Hold the MODE button on the interface for 2 seconds. The MODE light flashes orange every second.
- Press WPS on the router. Routers typically allow about two minutes for this.
- Success shows as the NET light glowing solid green for 5 seconds.
- Open the app, enter the MAC address and ID, and add the unit.
If the ERR light comes on orange for 5 seconds instead, the pairing did not take. Mitsubishi notes that the current interface does not require a router with WPS at all, so switching to access point mode is the sensible next move rather than repeating WPS.
What the four lights mean
The interface has four indicators and they tell you exactly where a failed setup stopped.
| Light | Colour | What it reports |
|---|---|---|
| UNIT | Green | The connection between the interface and the indoor unit |
| MODE | Orange | Access point or WPS mode is active |
| NET | Green | The connection to your router and the network |
| ERR | Orange | A network error |
A successful connection shows as the MODE light flashing orange every 5 seconds and the UNIT light flashing green every 5 seconds. At that point the unit is ready to be claimed in the app.
Reading the lights tells you which half of the problem you have. A healthy UNIT light with a dead NET light means the adaptor is talking to the air conditioner but not to your router, which points back at the 2.4 GHz question. The reverse means a wiring or fitting issue inside the unit, which is a technician job.
What the app can actually do
More than most people use it for. Mitsubishi publishes the following.
- Power on and off.
- All the operating modes, auto, heat, cool, dry and fan.
- Set temperature, and the current room temperature as measured by the unit.
- Fan speed, from one through five or auto.
- Airflow direction and vane position, on compatible wall mounted and floor console units.
- Zone control, on compatible ducted systems.
- A seven day programmable timer.
- Minimum and maximum temperature rules, which stop anyone setting the unit to extremes.
- Group control of several units together.
- A holiday mode that disables all rules.
Mitsubishi also publishes that fault codes can be sent to your phone, which is genuinely useful, because it means you have the code before you call anyone.
The limit worth knowing is that control runs through the cloud service. Without a working internet connection there is no local control, so a router outage means the app stops even though you and the air conditioner are in the same house.
Zone control on a ducted Mitsubishi
If your system is ducted and fitted with a compatible zone controller, the app gives you something the wall controller makes tedious. Individual zones can be opened and closed from your phone.
That matters more than it sounds in a Melbourne house. Closing bedroom zones during the day and living zones overnight is the single cheapest change most ducted owners can make, and it only happens consistently when it takes two taps rather than a walk to the hallway controller.
Mitsubishi publishes zone control as available on compatible ducted systems only, so it is worth confirming with your installer rather than assuming. Airflow direction control has a similar limit, published as available on compatible wall mounted and floor console units.
Is Wi Fi worth having on an air conditioner?
An honest answer rather than a sales one. It depends on how you use the system.
If you run the air conditioner on a predictable schedule, the handheld remote already has a weekly timer and the app adds convenience rather than capability. The seven day timer in the app does the same job.
Where it earns its place is less predictable households. Coming home at different times, wanting the house warm before you arrive on a cold morning, or wanting to check from work whether somebody left it running. Mitsubishi publishes pre cooling and pre warming before arriving home as one of the reasons for it.
The two features that are genuinely hard to replicate any other way are the minimum and maximum temperature rules, which stop a unit being set to 16 degrees in summer by somebody in a hurry, and fault code notifications, which turn a vague complaint into a specific one before a technician is even called.
For a ducted system with zoning, the case is stronger again, because zone control from a phone changes behaviour in a way a hallway controller does not.
The timer conflict nobody warns you about
This one causes real confusion and Mitsubishi states it plainly.
If you use the timer function in the app, delete any timer settings in your local controllers, and the same in reverse. Two schedules running against each other produce a unit that switches on and off at times neither of them specifies, and it looks exactly like a fault.
Pick one place to hold your schedule. If you are going to use the app, clear the weekly timer on the handheld remote first.
When it drops off the network
Mitsubishi publishes several causes worth ruling out before assuming hardware.
- Poor signal strength, particularly near metal objects. An adaptor inside a metal chassis in a ceiling space is a harder path than one on a wall.
- Radio interference from cordless phones and microwaves, both of which sit in the same 2.4 GHz band.
- A poor internet connection, which Mitsubishi notes will be visible on other connected devices too.
- The router reaching its limit on how many devices it will connect.
If the lights are not showing the patterns above, the published advice is to contact your installer or work through the installation manual rather than keep retrying.
Starting the pairing over
There is a reset on the interface, and the published durations differ between Mitsubishi documents, so treat it carefully.
The installation guide publishes holding the RESET button for 2 seconds to reboot the system, and 14 seconds to return it to factory defaults. That second one carries a warning worth reading twice. All configuration information will be lost, which means the unit has to be added to the app again from scratch.
The user manual publishes a 15 second hold to restart the pairing process. The two documents do not agree, so if you are going to do it, the safe approach is a short reboot first and a full reset only if that changes nothing.
Voice assistants
Mitsubishi Electric Australia publishes support for Amazon Alexa, which needs an Amazon Echo device, and for Google Assistant, which needs a Google Home speaker.
Apple Siri and HomeKit support is not published for the Australian app. If that matters to you, it is worth confirming before buying an adaptor on that basis.
Common questions about Mitsubishi Wi Fi
Why will it not connect to my Wi Fi?
In most cases, the network is 5 GHz. Mitsubishi publishes that 2.4 GHz needs to be enabled on dual band routers. Check that first, then check the encryption is WPA2 with AES.
Can I add Wi Fi to an older Mitsubishi?
If the indoor unit was manufactured after January 2015 and is an M Series, P Series or CITY MULTI unit, Mitsubishi publishes the MAC 568IF E as compatible. It has to be fitted to the control board, so it is an installer job rather than a plug in accessory.
Does the app work without internet?
No. Control runs through the cloud service, so an internet outage stops the app even from inside the house. The handheld remote keeps working normally.
Why does my air conditioner turn on at odd times?
Almost always two schedules fighting. Mitsubishi asks you to delete timer settings in local controllers when using the app timer, and the reverse. Clear one of them.
Who do I call about the app?
Mitsubishi Electric Australia publishes a dedicated Wi Fi Control support line on 1300 728 119, open Monday to Friday. That is a different number from general after sales support, which is worth knowing before you spend twenty minutes in the wrong queue.
Worth doing once it is connected
Set a minimum and maximum temperature rule, because it quietly prevents the expensive settings. Build one seven day schedule and delete the timer on the handheld so the two cannot conflict. And turn on fault code notifications, so the next time something goes wrong you already have the information a technician needs.
