Sentence 5.2.11.1.(4)

Intent 1:

To limit the probability that controls required by Sentence (1) will be improperly designed such that

• lowering a heating thermostat set-point triggers cooling energy to be used to reach the lowered heating setting, or

• raising a cooling thermostat set-point triggers heating energy to be used to reach the raised cooling setting.

This is to limit the probability of the 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.
