Turning off a light when it’s no longer required is a standard way of conserving energy and keeping power bills contained. But leaving an air conditioner on in an unused room for just one hour can sometimes equate to leaving 10 light bulbs on for the same period. So there goes your savings!
ESP Plus and ESP Ultima, by Australian air conditioning company ActronAir, offer an Energy Smart Zoning feature in their ducted systems. This zoning feature allows areas or rooms to be turned off when not in use, saving on running costs. Their Energy Smart Zoning intuitively matches the right amount of airflow according to how many zones are on, even down to just one room. ESP Ultima also allows different temperatures to be set in different zones of the house. For instance, a sleeping child can have the room a little warmer; while the kitchen can be set at a cooler temperature. Up to eight temperature zones can be created with ESP Ultima.
