The temperature control is in the tip cartridge. This is one of the biggest advantages of a system like this, you never need to calibrate it. If the temp is "off" you throw out the tip cartridge and get a new one. The temperature regulation is also extremely good.
You can buy tips for different temperatures, for the MX-500 (What i use) there are 4 different temperature control ranges. For the part you linked there are 3 temp ranges:
"F = FR4 / Fiber Glass for most standard applications. Two other series also available, just replace F with either T or C. T = Temperature Sensitive, C = Ceramic"
When you order tips use F/T/C in the tip part number to get the correct temp range.
I don't know about the tips for the part you listed but the MX-500 tips the 4 temperature grades are 575F,675F,775F,905F.
Judging by the name of the temperature grades for the iron you linked either the 575 or 675 is the one thats not available.
