Most split systems work until they are turned off. But there are independent control systems, the so -called inverter ones, which support those climate parameters in the room that were set for it. Thanks to this system, you can not be afraid to be under a wave of air or draft, temperature and voltage drops, like a split system without an inverter. You can go to bed with them, spend the night and wake up in an individual comfortable atmosphere. They work in one sound range, and less noisy. When setting a timer, work is ensured in the intervals of time, which for each their own. Blinds that are responsible for the distribution of air, warm or cold, in the room you can also control both automatically and manually. Automatic operation of the system, turning on and off, proceeds from the climate parameters in the room and specified by the user.
