Smart Air Conditioner Controller: Remotec ZXT-800 for Z-Wave AC & AV Control
The Remotec ZXT-800 Z-Wave to IR Converter for AC & AV Control is a smart automation bridge designed to connect traditional infrared-controlled appliances with a modern Z-Wave smart home or building automation system. For homes, offices, apartments, assisted living environments, and smart automation projects, the ZXT-800 provides a practical way to control split air conditioners and entertainment devices through a compatible Z-Wave gateway.
Many air conditioners, televisions, audio systems, and AV devices still rely on infrared remote controls. While these remotes are simple to use, they are not always convenient for automation. They usually require line-of-sight operation, manual control, and separate management for each device. The Remotec ZXT-800 solves this problem by receiving Z-Wave commands from a compatible gateway and converting those commands into infrared signals that your AC or AV equipment can understand.
Quick Overview
- Working as a Z-Wave thermostat
- Convert Z-Wave commands to IR signal
- Flawlessly work with any Z-wave compliant gateway
- Built-in temperature and humidity sensor
- Working on battery (3x AAA batteries) or micro USB power

Product Details
What Is the Remotec ZXT-800?
The Remotec ZXT-800 is a Z-Wave Plus compliant Z-Wave-to-IR bridge. It works as a smart translator between your Z-Wave automation system and your infrared-controlled devices. When your Z-Wave gateway sends a command, the ZXT-800 converts that command into the correct IR signal, allowing compatible split air conditioners and entertainment devices to respond as if they were being controlled by their original remote.
For air conditioning control, the ZXT-800 can work as a Z-Wave thermostat device. This means users can manage key AC functions such as temperature adjustment through their Z-Wave system, depending on the gateway, device compatibility, and selected IR code. Instead of using a traditional AC remote, users can control their air conditioner from a smart home app, automation scene, or compatible Z-Wave controller.
Designed for Split Air Conditioning and AV Control
One of the key advantages of the Remotec ZXT-800 is its ability to support both AC and AV control. It is suitable for split air conditioners as well as entertainment devices that operate using infrared commands. This makes it a flexible solution for residential smart homes, commercial automation projects, meeting rooms, media rooms, offices, and accessibility-focused installations.
For air conditioning, the ZXT-800 can help users centralise climate control through a Z-Wave platform. For AV equipment, it can help simplify the control of devices such as televisions, audio systems, and other IR-based entertainment products. Instead of managing multiple remote controls, users can bring compatible devices into one smart control environment.
Built-In and Cloud-Stored IR Code Library
The ZXT-800 includes access to a comprehensive built-in and cloud-stored IR database. This IR library allows the device to support a wide range of brands and models worldwide. During setup, users can select and download the correct IR code for their specific AC or AV device using the Conexum ZXT-800 app.
This is especially useful when working with different brands of split systems or entertainment equipment. Rather than manually learning every command, the app-based IR code setup makes configuration more efficient. The Conexum ZXT-800 app is available for iOS and Android devices, and setup is completed through Bluetooth.
How the ZXT-800 Works
The ZXT-800 operates as a Z-Wave slave device. In simple terms, it does not work as the main controller by itself. Instead, it is added to a compatible Z-Wave gateway or controller, which sends commands to the unit.
Once connected, the process is straightforward. The user sends a command from the Z-Wave gateway or smart home app. The ZXT-800 receives that Z-Wave command and translates it into an infrared signal. The IR signal is then sent to the air conditioner or AV device, allowing it to perform the requested action.
This makes the ZXT-800 an ideal bridge for devices that do not have native Z-Wave connectivity but can still be controlled by infrared.

Built-In Temperature and Humidity Sensor
Another useful feature of the Remotec ZXT-800 is its built-in temperature and humidity sensor. This adds more value for air conditioning automation because the Z-Wave system can receive environmental information from the room.
For example, a smart home system may use temperature information to help manage comfort, energy efficiency, or automated scenes. In a residential setting, this can help maintain a more comfortable indoor environment. In a commercial or assisted living setting, it can support easier monitoring and control of climate conditions.
Flexible Power Options
The Remotec ZXT-800 can be powered in two ways: by 3 x AAA batteries or by Micro USB power. This gives installers and users flexibility depending on the location of the device.
Battery operation is useful where running a cable is not convenient or where a clean installation is preferred. Micro USB power is a strong option for fixed installations where continuous power is available. For best performance, especially in permanent smart home or commercial applications, USB power may be preferred because it reduces the need for battery replacement.
Z-Wave Plus and Security Enabled Operation
The ZXT-800 is a security enabled Z-Wave Plus device. To fully utilise its security features, it should be used with a security enabled Z-Wave Plus controller. This is important for smart automation projects where reliability, compatibility, and secure communication are required.
Z-Wave Plus also helps deliver improved wireless performance compared with older generations of Z-Wave products, depending on the complete network setup. When used as part of a well-planned Z-Wave network, the ZXT-800 can become a reliable part of a broader automation system.
Compatible Z-Wave Controllers in Australia
For Australian installations, it is important to use products that operate on the correct Australian Z-Wave frequency. The ZXT-800 supports the Australian certified Z-Wave frequency of 921.42MHz and integrates with selected Australian certified Z-Wave controllers.
Compatible controllers include:
VeraPlus, VeraEdge, Fibaro Home Center 2, Fibaro Home Center Lite, and the Remotec Z-Wave Universal Remote Controller.
Compatibility may depend on the gateway firmware, configuration method, IR code selection, and the specific device being controlled. For professional installation, it is recommended to confirm controller compatibility before supplying or installing the product.
Ideal Applications
The Remotec ZXT-800 is suitable for a wide range of automation projects. In smart homes, it can help integrate split air conditioning into a central control system. In offices and meeting rooms, it can simplify the control of AV equipment and climate settings. In apartments and townhouses, it provides a compact way to add IR-based devices into a Z-Wave ecosystem.
It is also useful for accessibility and assisted living applications, where users may benefit from easier control of air conditioning or entertainment devices through one app, remote interface, automation scene, or voice-compatible smart home system connected through the main gateway.
Why Choose the Remotec ZXT-800?
The main advantage of the Remotec ZXT-800 is that it extends the capability of a Z-Wave system without requiring the replacement of existing IR-controlled equipment. Many air conditioners and entertainment devices are still perfectly functional, but they do not support smart control natively. The ZXT-800 provides a practical upgrade path by bridging these devices into a Z-Wave environment.
Its compact design, flexible power options, built-in temperature and humidity sensor, app-based IR code setup, and support for AC and AV control make it a versatile solution for modern automation projects.

Conclusion
The Remotec ZXT-800 Z-Wave to IR Converter for AC & AV Control is a smart and flexible solution for connecting infrared-controlled air conditioners and entertainment devices to a Z-Wave automation system. By converting Z-Wave commands into IR signals, it allows users to manage compatible split AC units and AV devices through a central smart home gateway.
With Z-Wave Plus support, built-in temperature and humidity sensing, cloud-stored IR code access, Bluetooth app setup, and flexible battery or Micro USB power, the ZXT-800 is a practical product for residential, commercial, and accessibility-focused automation projects.
For users who already have a Z-Wave system and want to bring traditional IR devices into their smart control environment, the Remotec ZXT-800 offers a simple and effective bridge between existing appliances and modern automation.
