240 volt Conversion
The original controller was designed for operation on 110VAC and many of the parts were specified for 110V. The board will operate at other voltages, however a number of changes need to be made.
The first decision to be made is what voltage you want to switch. The triacs are responsible for switching the primary voltage. The is no reason that the primary voltage for the TRIACs could not be 240VAC or 24VAC, however the circuit will need to be modified.
One of the major changes is the ZC detect section of the controller. The original circuit specified a H11AA1 for the optoisolator, with two 15k 1watt resistors for current limiting. Details on the H11AA1 can be found here

24VAC switching.
Parts Required and changes.
Gate Resistors - The original value for the gate resistors (item 7) was 180 ohms. For 24VAC operation, the gate resistors need to be changed to 33 ohms.
240VAC switching.
Parts Required and changes.
Gate Resistors - The original value for the gate resistors (item 7) was 180 ohms. For 240VAC operation, the gate resistors need to be changed to 360 ohms.
Computer feed/power cable
Now you have installed all the parts, the next decision is how you will connect the controller to the PC, and how you will power the board.
The majority of the controller is run from a 5 volt DC regulator.
