POINT!
| When the room temperature is high, the (red→blue) negative feedback inhibits the heater (function, such as by turning the power off). |
① Summer came. Because of the summer heat, room temperature increases. A heater increases room temperature. These are in the same (red) direction.
② Since these are in the same (red) direction, the negative feedback inhibits (blue) the heater (function, such as by turning off the power). The room temperature-increasing effect of the heater is weakened, and the increased room temperature is decreased towards baseline room temperature.
