Placebo has taken a form in various areas of Science. In most cases, the placebo is shown to copy or even exceed the effects produced by active treatments such as medications and therapies. Generally Placebo effect is defined as giving simulated, fake, or inactive treatment intended to deceive its recipients. It works because of the brain's role in the physiological health.

In the HVAC (Heating, Ventilating, and Air Conditioning) industry, placebo is seen in the form of the "Placebo button". This button may seem to change the temperature by going up or down but it actually is not. However, there is a chance that you will feel cooler or warmer even though there has been no "actual" change to the machine's temperature.
This phenomenon is illustrated in a 2014 study by Aircon Off. They built a hand-held aircon remote that makes the air conditioning operating range appear wider than it actually is by displaying false readings. For example, the user may perceive that the temperature can go as low as 17°C but the air conditioner (AC) is actually operating no lower than 22°C. The study has been shown to work! It helped increase power savings without generating negative feedback from its users.

This Placebo button works because feeling hot or cold is mostly produced by your brain. HVAC engineer named Joe Oliveri even argues that thermal comfort is 10% physical and 90% mental. The numbers may be exaggerated but the underlying idea is found to be relatively true. In fact, a research led by neuroscientist Mark Zylka found an interaction between the neural circuits that detect cold and hot stimuli. For example, cold perception was enhanced as the neural circuitry for heat was inactive. So let your body and mind adjust to temperature first before pressing any buttons.
