Web page Technical error Be careful when ordering this Item. I was shopping for a programmable thermostat when I ran across this item. I thought it would be great to see the outside temperature displayed when checking my thermostat. I purchased a Honeywell RTH8500D thermostat to use with this sensor. The thermostat was on sale and the Amazon web page for the sensor indicated it would work with the thermostat. I copied and pasted part of the technical details from the web page for the sensor below:
Temp Sensor Review Really appreciate the chart with the resistance/temp values. Leads are too short, though, and will not fit into the S1/S2 terminal blocks on the Honeywell 8000 series thermostats without stripping away some of the strands to make the conductor pack thinner. Overall, though a quality product.
Concerned about the Calibration I checked resistance out of the box against reference temperatures and calibration was off by 1-3 deg. C. The error is not linear, below -20C it reads 1-2 deg C colder and above zero it is reading 1-2 deg warmer. It not cost effective to return it because the refund of canadian inport duty and taxes is a hassel.
