HVAC controllers to regulate temperature and relative humidity. Regulating temperature and relative humidity in buildings is essential for maintaining occupant comfort and well-being. Proper temperature control ensures that indoor spaces are conducive to productivity and comfort, preventing discomfort from extreme heat or cold. Managing relative humidity is equally crucial, as excessive humidity can lead to mold growth and dust mites, negatively impacting indoor air quality and health. Moreover, maintaining optimal conditions can protect building materials and equipment from damage caused by extreme temperature and humidity fluctuations. Overall, effective regulation of temperature and relative humidity in buildings contributes to a healthier, more comfortable, and sustainable indoor environment.
