It should be used when the temperature outside is between 23 and 76 degrees and is meant to supplement, not replace, a primary heat source. The unique remote control features a built-in thermostat that senses the room temperature, displaying it on the remote's LCD screen, and sends a signal to the AC unit every 3 minutes for accurate cooling. The energy-saving features, including the energy saver mode, sleep mode, and programmable 24-hour timer, help reduce electricity costs by optimizing efficiency. The Check Filter alert lets you know when it's time to clean the mesh filter, ensuring consistent performance.
