1. Compatibility check: Does your air conditioner support Wi-Fi?

Not all models Royal Clima are equipped with a built-in Wi-Fi module. To avoid wasting time, first make sure your device supports remote control. Here's how:

  • 🔍 Look at box or passport of the device - look for the inscriptions Wi-Fi Ready, Smart Control or logo Tuya/Smart Life.
  • 📋 Check the model in official catalog (series RC-PW, RC-IW, RC-MW usually support connection).
  • 🔧 If there is no module, but there is a connector for it (for example, on the control board), you can purchase an external adapter Royal Clima Wi-Fi Kit (article RC-WF01).

Models no connection possible:

  • 🚫 Old episodes RC-N (until 2019)
  • 🚫 Budget models without an inverter (for example, Royal Clima RC-O07)
  • 🚫 Industrial air conditioners (series RC-C)
What does a Wi-Fi module in an air conditioner look like?

Typically, this is a small board with an antenna connected to the main control board. It may be labeled "Wi-Fi" or the Tuya logo. In some models, the module is built into the remote control (for example, in the RC-IW series).

If your model supports Wi-Fi, but you are unsure of the firmware version, try updating it through the service menu (instructions in section 5). Air conditioners from 2023–2026 typically don't require updates, but units from 2020–2021 may require firmware updates to work properly with new routers..

2. Preparing the router: why doesn't the air conditioner see the network?

Most connection problems are not related to the air conditioner, but to the router settings. Royal Clima (like other smart devices) requires:

  • 📶 Network 2.4 GHz (5 GHz is not supported!
  • 🔒 Open access or simple password (no special characters)
  • 🌐 DHCP server (automatic IP assignment)

If your router only works in the range 5 GHz, you will have to:

  1. Go to the router settings (usually at the address 192.168.0.1 or 192.168.1.1).
  2. Enable mode 2.4 GHz (on the menu Wireless Network → Wi-Fi Settings).
  3. Set a separate SSID for 2.4 GHz (For example, MyWiFi_2G).
