Air Conditioning Controller
 
INTRODUCTION –
 
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 Conditioner’s parameters has become necessary. A/C CONTROLLER is most useful for controlling A/Cs. This instrument is able to maintain Room temperature with an accuracy of 0.1 C by automatic measurement of Room temperature and accordingly con trolling A/C ON / OFF. It also protects Costly Air conditioner from Unhealthy conditions. Such as over load / under load, under / over voltage. HP / LP, Fire etc . by automatically cutting off supply to it.
