Thanks to Barrie, I installed one of the new Fenwal probes at the end of the wire and I now have a temperature reading. However, two problems remain, 1. The temp is in C rather than F and 2., the temp is somewhat inaccurate. Does anyone know how to change the reading from C to F? and what size range of tweaking resistors to put into the line to calibrate the reading (or an other technique)?
