I have recently been assigned to work on project which involves the control of geysers. The main objective of the project is to reduce power consumption of geyser by only switching them on when hot water is required. The geyser should be on from 0500hrs to about 0900hrs and then swicth off for the rest of the day. It should switch on again from 1700hrs to 2200hrs and then off for the night. I intend to use a programmable microcontroller but the main issue is the interfacing of the microprocessor and the geyser circuit. The geyser is fed from a 220V supply and its rating is between 4 and 6 kW. Maybe you can alo suggest the type of microcontroller to use. What type of power supply is the best for this circuit given that the whole circuit has to fit in a 20cm by 10cm box. I look forward to hear from you ladies and gentleman. Chinamasa
