Which is high temperature, Hi or Lo?
2 Answers
Hi represents high temperature, Lo represents low temperature. HI is the abbreviation of the English word 'high', meaning high, and LO is the abbreviation of 'low', meaning low. Principle of seat heating: Seat heating utilizes electric heating wires inside the seat to warm the interior of the seat, and transfers the heat to the occupant through thermal conduction, improving the discomfort caused by the seat being too cold after prolonged parking in winter. Function of heated seats: Electrically heated seats are one of the luxury features of cars. Equipping leather seats in luxury cars with electric heating devices means that in the freezing winter, sitting down won't land you on a cold leather seat but instead provides a warm and comfortable feeling, which is particularly appreciated in northern regions.
Over the years of driving, I've frequently encountered this issue. On car air conditioning or heating controls, 'Hi' undoubtedly represents high temperature. For instance, when it's freezing in winter and I get into the car, I turn the knob to the 'Hi' position, and warm air blows out immediately, quickly warming up the interior. 'Lo', on the other hand, is the setting for low temperature or low fan speed, suitable for using the AC in summer. This design is consistent across most vehicles, from older models to newer ones. The rationale behind it is simple: 'Hi' comes from the English word 'high', indicating high intensity; 'Lo' comes from 'low', representing a low state. In practical use, it's important to note that setting the wrong temperature with too large a difference can make driving uncomfortable or even distracting. My habit is to confirm the direction first after getting in the car to ensure proper adjustment. Through long-term use, I've found that regularly cleaning the AC filter can make the 'Hi' setting respond faster. Additionally, some automatic systems can intelligently switch fan speeds, but the basic logic remains unchanged. Remembering 'Hi' for heat and 'Lo' for cold makes for a more comfortable and safer drive.
