Outline of function
The temperature is controlled in unique V-shape pattern within the range of about 2°C upper
and lower. First the room temperature is gradually lowered at the beginning of sleep to
induce the lowering of body temperature in sleeping.
Then, the room temperature is kept constant, and when the preset wake-up time
approaches, the room temperature is gradually raised to induce the raising of body
temperature before waking.

V-shape pattern temperature control system

conditioner’s temperature control.
