Circuit Diagram:
Here we used two timer for this simple automation. Please read the diagram carefully.
220V is pass through Timer-01 NC contact 4 & 1 which goes to coil pin 2. Then Timer-02 energize. Suppose after five minutes timer-02 contact changed and 220V passed through NO contact 1 & 3 to Timer-01 coil pin 2 which energize Timer-01 coil. Suppose, after ten minutes Timer-01 contact changed which reset the Timer-02. Then, cycle again start & continue forever.
