Sentence 5.2.8.8.(3)

Intent 1:

To limit the probability that a system that controls the temperature of a space by mixing heated supply air and cooled supply air will not

• automatically adjust the temperature of the warm supply air to the lowest temperature that will satisfy the temperature-control zone requiring the warmest air, and
• automatically adjust the temperature of the cool supply air to the highest temperature that will satisfy the temperature-control zone requiring the coolest air.

This is to limit the probability of unnecessary consumption of energy for heating and cooling, which could lead to excessive use of energy, which could lead to an unacceptable effect on the environment.
