I recently bought an aircon .5 hp carrier window type. the sales rep told me sa lahat nilang aircon na ibinebenta yun ang pinaka energy efficient. Inexplain nya thru the yellow card attached (yung energy guide) na approx ganun mapapdagdag sa electric bill ko. There was a formula given how to solve how much it will cost. But eventhough I have bought that unit already. There was something he could not explain to me. but how about the formula to find out its exact wattage at different settings? Hope someone could clarify this. Here is the case. It is stated that the power consumption of that unit is 519 W. all the way ba once I turned on the unit yun ang consumption nya? I mean what if naka low cool ang settings mas mababa sa 519 consumption nya? Or if naka turbo cool mas malaki bas a 519 ang consumption niya? Eh yung thermostat? For example I put it on low cool and the thermostat at 2 how will I know how much wattage it is at that setting?
