NOTES
1) All circuits connected by broken lines are optional.
2) C7 is used only with electronic extension and R7 is used only with mechanical switch.
3) Connection between Pin 1 & Pin 2 should be broken when DOZE circuit is used.
4) Use Connection A when Neutral is not available. Use Connection B when Neutral is available.
5) Connection between Pin 6 & Pin 7 should be broken when EXT is used.
