I have a question about ADN8834, in the Datasheet there is a typical application circuit on Page 14, as shown belowTypical application circuit

I want to know what the function of the two resistors.  What is the meaning that get the Vref/2? If I would like to contol the temprature by external voltage of DAC, Do I need to reserve the resistors?

Thanks in advance.
