Hi, I have a question about the AD590 temperature sensor.

 

I am trying to create a circuit to contol temperature withing a range of 17 degC and 21 degC.

 

is this possible using some sort of op amp to act as the hysterisis of the system... say setpoint is 19 degC plus/minus 2 degrees.

 

i think i am on the right track, what are your thoughts?

 

how would i select the R set, RH and RL in order to power on the furnace when below the low set point and turn off when above the high
