Types of control for hidden and cassette air conditioners: Wall control (fixed thermostat): It is a digital control panel installed on one of the room walls. Through it, you can adjust the temperature, set the fan speed, and choose the cooling or heating mode. Wireless remote control: Some modern hidden and cassette air conditioner models support regular wireless remote control to adjust the temperature and operating modes remotely, especially if they are equipped with a visible signal receiver (lens) in the ceiling decor. Smart control via Wi-Fi: Many systems have the feature of connecting to the internet, allowing you to fully control the air conditioning using dedicated applications on your smartphone from anywhere.
