Hello,
This is a schematic for a Mains pump motor driver.

Do you believe that the "H/L" input is for selecting wither UK or USA mains? (i.e. 120VAC or 240VAC?)
MOC3063 DATASHEET:

Also, MOC3063 is a zero-crossing opto-triac driver, surely this is unsuitable for IC2?
.....because surely that opto-triac driver (IC2) should just be either ON or OFF all the time, depending on whether its 120VAC or 240VAC?
