from what i understand, the white 5W resistor on the heatsink of .33 Ohm needs to be changed to 0.1 Ohm and as David says you need to input 5.5V instead of 5V.
I used this driver / tec / thermistor combo on the LEM in the UK.
Worked like a charm, kept the diode block very stable between 19,4 and 19,8 degrees.
Someone suggested this might be a little low and that to prevent condensation i had to turn it up to 25 degrees. But it worked stable as a rock, so i can really recommend this.
I didn't fail !
I just found out 10,000 ways that didn't work.
