Losing your air conditioner remote is one of those small problems that quickly turns into a big inconvenience.
Whether you’re using a Mitsubishi, Fujitsu, or any other ductless air conditioning system, the remote is your primary way to control comfort—temperature, fan speed, and operating modes all depend on it.
Without the remote, you’re often left with limited manual controls (if any), making it difficult to adjust settings or optimize energy use.
Even worse, finding a replacement remote can be confusing or sometimes impossible—especially for older or discontinued models.
But today, there’s a smarter alternative. Instead of replacing your lost remote, you can upgrade your entire system with the Klima Smart Controller, turning your air conditioner into a fully connected, smart home device.
What Is a Remote Control?
A mini-split air conditioner remote control is a wireless infrared (IR) device that communicates directly with your indoor unit.
It acts as the command center for your Mitsubishi mini-split system, allowing you to fine-tune your indoor environment without physically interacting with the unit.
For example, a typical Mitsubishi remote control includes:
-
Power control – Turn the AC on or off instantly
-
Temperature adjustment – Set your preferred cooling or heating level
-
Mode selection – Choose between cool, heat, dry, or fan modes
-
Fan speed control – Adjust airflow intensity
Most remotes also feature an LCD screen that displays current settings, timers, and operating status.
While these remotes are convenient, they come with limitations:
-
They are easy to lose due to their small size
-
They require line-of-sight to function properly
-
They only work within a limited range
-
They cannot be controlled remotely (outside the room)
Remote Control Codes
Each remote operates using specific infrared codes that must match the exact model of your air conditioning unit.
This is why manufacturers like Mitsubishi produce dozens of remote variations, such as:
-
KM04A / KP0A
-
KM05B
-
KM09A / KM15K
-
KM08A / KM09D
-
SG15D
-
SG17B
-
SG18D
-
XG19D / XG19E / XG19F
Each of these remotes corresponds to specific indoor unit models, configurations, and even production years. Some remotes are marked as discontinued, making them extremely difficult to find in the market.
Because of this complexity:
-
Buying the wrong remote is very common
-
Replacement costs can add up
-
Compatibility issues can prevent full functionality
In short, losing your original remote often leads to frustration and trial-and-error.
The Solution – Klima Smart Controller
Instead of dealing with remote codes and compatibility issues, Klima provides a modern, all-in-one solution.

What Is Klima?
Klima is a smart controller designed specifically for ductless air conditioners, including:
-
Mini-split systems, like Mitsubishi mini-split’s
-
Window air conditioners
-
Portable AC units
These systems typically rely on infrared remotes, which means Klima can replicate and replace your existing remote entirely.
Once installed, Klima connects your air conditioner to the Boldr Energy app, allowing you to control your AC directly from your smartphone.
What Makes It Different?
Unlike a traditional remote, Klima doesn’t just send commands—it transforms your AC into a smart climate system that can:
-
Learn your habits
-
Automate operations
-
Optimize energy usage through smart features like Smart Scheduling.
-
Provide real-time insights of your energy bill
This means you’re no longer dependent on a physical remote at all.

Klima’s Smart Features
Klima includes a wide range of automation and monitoring tools that help homeowners control their air conditioning more efficiently.
1. Remote Access
Klima allows you to control your Mitsubishi air conditioner from anywhere using the Boldr Energy app.
Whether you are at work, traveling, or relaxing in another room, you can instantly:
-
Adjust temperature settings
-
Turn the AC on or off
-
Change cooling modes
-
Use Klima’s other smart features
2. Location-Based Automation
Klima can automatically detect when everyone leaves the house.
When the home becomes empty, Klima shuts off your ductless Mitsubishi air conditioner to prevent unnecessary energy use.
When someone returns, the system automatically turns back on to restore a comfortable temperature.

3. Smart Scheduling
Klima’s scheduling system allows you to automate cooling based on your daily routine.
You can program your air conditioner to:
-
Turn off when you leave for work
-
Start cooling before you return home
-
Adjust temperature overnight
This prevents your ductless system from running when it isn’t needed.
4. Health Monitoring
Klima continuously monitors the operation of your air conditioning system.
If a potential issue appears, the Boldr Energy app sends an alert so you can address problems early before they become expensive repairs.
5. Household Management
Multiple users can access the Boldr Energy app.
You can give family members or guests permission to adjust temperature settings or provide full control depending on the access level you assign, through the Boldr Energy app.
6. Cost Monitoring
Klima tracks real-time energy usage and estimates your monthly electricity costs.
This insight helps homeowners understand how their air conditioner is consuming power and make smarter decisions about energy usage.
Smart Home Compatibility
Klima integrates with major smart home platforms, allowing you to control your AC using voice commands or automation routines.
Supported platforms include:
-
Apple Home
-
Apple HomeKit
-
Google Home
-
Google Assistant

Amazon Alexa
-
Home Assistant
-
SmartThings
This means you can simply say things like:
"Alexa, turn on the air conditioner."
