Help with analog dimming circuit connected to microcontroller

Hello everyone, I would like some assistance on this circuit which I plan to modify. The analog circuit attached is a dimming circuit application note for a PIC microcontroller. It's intended for the use on 120Vrms main line connected to the light. I would like to know how do you modify this circuit if it is intended for use on 240Vrms connected to the light? I would very much appreciate if someone could give me guidelines on how, since I don't even know where to start!

Thank you in advance for your help.
