MOTION SENSITIVE DETECTION: A built-in motion sensor helps save energy. If no motion is detected for a set period of 90 seconds, 5 minutes, or 10 minutes, the heater will shut off to conserve power. Operation will resume once motion is detected again. THREE (3) OUTPUT MODES: Breeze/Medium/Turbo (Max. 120 sq ft coverage) From a quiet warm breeze to rapid heating; three available fan modes help enrich your space, whether in a living room or bedroom. SAFE AROUND CHILDREN: The child lock feature disables the control panel to prevent unintentional setting changes. You don't have to worry about children accidentally making it too hot. Easily toggle the lock on/off by pressing and holding the corresponding button on the control panel. TIP-OVER SAFETY SWITCH: If the unit is tipped over or tilted by 45° or more, the safety switch trips and shuts it down immediately. In a busy room, things can be unpredictable. This safety feature helps prevent the heater from damaging the area. AUTOMATIC SHUTDOWN: This feature will shut off the heater to save energy if it runs for longer than 3 hours continuously. No need to worry about forgetting to shut it down. This energy-saving feature also helps keep your home safe. Perfect for houses and apartments.
