Degrees Celsius. If the temperature rises above this level, the air conditioning system will turn on to bring the temperature back down. If the temperature drops below 21 degrees Celsius, the heating system will turn on to bring the temperature back up. This is known as a thermostat, which controls the temperature in the building to ensure that it stays within a certain range. Maintaining a constant temperature not only ensures comfort but also helps to save energy and reduce costs.
