Losing your Fujitsu air conditioner remote can be more than just an inconvenience—it can completely disrupt your comfort.
Unlike TVs or other appliances, most ductless air conditioners rely heavily on their remote controls for operation. Without it, adjusting temperature, switching modes, or even turning the mini-split unit on can become frustrating or impossible.
But there’s good news: you don’t actually need your original remote anymore. With modern smart technology like the Klima Smart Controller, you can take full control of your Fujitsu mini-split and even upgrade it.
What Is a Remote Control?
A remote control for a ductless air conditioner is an infrared (IR) device that sends signals directly to your indoor unit. Every button you press—whether it’s temperature adjustment, fan speed, or mode selection—transmits a specific coded signal that the A/C understands.
Unlike wall thermostats in central HVAC systems, mini-splits and window units depend entirely on these remotes to function.
That’s why losing one can feel like losing control of your entire cooling system.
Fujitsu Mini-Split Remote Control Codes
Fujitsu mini-split air conditioners use specific remote models and corresponding IR codes to communicate with the unit. Some common Fujitsu remote models include:
-
AR-RAH1U / AR-RAH2U
-
AR-REB1U / AR-REB1E
-
AR-REF1U / AR-REF1E / AR-REF3E
-
AR-REY1U
-
AR-REW1U
-
AR-REM1U / AR-REM4E
-
AR-RPB1U / AR-RPB2U
-
AR-RCF1U
-
AR-RRH1U / AR-RRH2U
-
AR-RRG1U
-
AR-RED1U
Many of these remotes are also identified by numeric part numbers, such as:
-
9334141007 (AR-RPB1U)
-
9332438772 (AR-REY1U)
-
9352446283 (AR-REW1U)
-
9362142014 (AR-RRH2U)

The Solution — Klima Smart Controller
Instead of searching for a replacement remote, a smarter solution is to upgrade your system entirely.
What is Klima?
Klima is a smart controller designed specifically for ductless A/C systems, including mini-splits, window units, and portable air conditioners.
Since these systems use infrared remotes, Klima can replicate and replace those signals—no original remote required.
Once installed, Klima connects your air conditioner to the Boldr Energy app, allowing you to control and monitor your A/C directly from your smartphone.
Rather than operating your A/C manually, Klima transforms your unit into a fully connected smart climate system—improving comfort while helping reduce energy waste.
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.
