Under CALGreen landscape provisions, automatic irrigation systems installed for new construction are generally required to use what type of controller?
a.A simple manual timer set by the owner
b.A weather- or soil-moisture-based (smart) controller
c.No controller, relying on hand watering
d.A fixed clock with no sensor input
Giải thích
CALGreen requires weather- or soil-moisture-based controllers that adjust watering to actual conditions, saving water. A basic manual timer or a fixed clock with no sensor does not respond to weather, and eliminating the controller does not meet the water-efficiency requirement.
