MICROCONTROLLERS with their inherent advantages are being increasingly used in the industry.With growing shortage and escalating cost of Electrical Energy, accurate monitoring of Air Conditioning parameters has become necessary.6A/C CONTROLLER is most useful for controlling A/Cs. This instrument is able to maintain Room Temperature with an accuracy of 0.1 Degree Celsius by automatic measurement of Room temperature and accordingly controlling A/C ON/OFF. It also protects Costly Air conditioner from Unhealthy condition's such as over load/under load etc. by automatically cutting off the Load.
