The parts you describe would probabally need no conversion, IOW they should work at 240vac, you would need to find out how the low voltage is produced, usually through a switching supply to get the low voltage for the control logic etc. You could even hook it up to 240 1 phase and see if the logic and display come on as some switching supplies will operate over a wide range of voltages.
The Fan is usually fed from low voltage so check the voltage on that.
