22 CAR § 111-803. Automated controls

(a) Where possible, use automatic controls for HVACR systems and for lighting applications. (b) Space temperature and humidity should be controlled by automatic controls capable of maintaining the space set-point within a fixed upper limit and lower limit. (c) Where practical, provide for the automatic setback or setup of the space temperature during the unoccupied periods. (d) Avoid turning off systems where the rise in space temperature or humidity above the ASHRAE recommended maximums might result in damage to the building materials or growth of microbiological organisms. (e) Avoid exposing the building water systems or other components to potentially damaging freezing conditions. (f) Where possible, use space occupancy sensors such as motion sensors to control lighting and individual room air conditioning terminal units to allow setback or to turn out the lights when a space is unoccupied. (g) Where sufficient natural lighting exists due to windows or skylights, use automatic lighting controls to regulate the overall space lighting levels.
