Also, in Eric's circuit shown. What is U2 and are both U5 and U6 10k pots? I'm not understanding the specs on this with respect to the "wiper" being .49? What does that mean?
I don't have a concern about power usage since this will have a dedicated power supply and will not be powered via the 1-wire bus. There will be 12V sent out to the device and I'll use a 7805 right there with the sensor and electronics!
Thanks!

hi James,
The wiper of the potentiometer is assumed to be adjustable from 0 to 100% of the pots value, so .49 means the pot has been adjusted to 49% of its value.
