used to work for a company that manufactured a proprietary commercial
building control system. We tried for years to come up with an inexpensive
and reliable way to accurately measure temperature to +/- 0.1 degree that
didn't require field calibration. The only way we found to solve that
problem was to use expensive components (sensors, precision resistors, etc)
that significantly raised the price of the systems. Marketing balked at
the price and it never did happen.</span></font><o:p></o:p></p>

The Thermostat remote sensors and the Temp/Humidity sensors are mounted on

show.<o:p></o:p></span></font></p>
