The Remotec ZXT-600 AC Master Z-Wave (SKU: 4896628184903) is a sophisticated Z-Wave Plus certified bridge designed to bring traditional air conditioning units into the modern smart home ecosystem. By acting as a transparent Z-Wave-to-IR extender, it allows you to control split-system air conditioners and other infrared-controlled devices directly from your Z-Wave gateway or portable controller.

Intelligent Climate Integration
Equipped with a comprehensive, built-in library of IR codes and access to an ever-green cloud-based database, the ZXT-600 supports over 250 brands of air conditioning units. For models not found in the extensive library, the device features an advanced learning function, allowing it to capture and replicate IR signals from your existing remote control. This ensures almost universal compatibility with AC models worldwide.
Advanced Monitoring and Control
Beyond simple on/off functionality, the AC Master functions as a Z-Wave thermostat. It features an integrated temperature sensor that provides real-time room temperature feedback to your home gateway, allowing for the creation of automated schedules and climate routines to optimise energy efficiency and comfort. The device supports a variety of modes including Cool, Heat, Dry, and Fan Only, alongside temperature calibration to ensure precise readings.
Flexible Installation
Designed for versatility, the ZXT-600 can be powered by two AA batteries for a wire-free setup (operating in FLiRS mode for power saving) or via a micro USB cable for "Always Listening" operation. Its wide-angle, 5-direction IR emitter provides hemispherical coverage, while the 3.5mm jack allows for an external IR emitter cable to reach devices in enclosed spaces or to avoid signal saturation.
