We have a couple friends to thank for this information. Several months ago our good friend and fellow technician (Chris Aiello AKA J.C.A.) was looking for a diagnostic chart that offered the relationship of the ohms resistance at a given temperature for Honeywell Sensors. As it turned out though it was built into software that Honeywell uses there was nothing in a written format that could be referred to.

When Chris brought this to our attention I offered to contact a friend of mine from Honeywell (Henry “Chip” Troost) Henry promised me that once he got ahead on some projects he was currently working on and we got through the Holidays (this was around Christmas 2006) He would work on extracting the info from the software and convert into a Word format. Be the man of his word that he is. He did just that and he recently confirmed that to the best of his knowledge the information is correct and that I may share it with all of you. Henry and I both truly hope this may make your jobs a little easier while troubleshooting sensors on some of the Honeywell controls.

So can I respectfully ask that we all post a great big thank you to both Henry and Chris for raising the bar and making our lives within the industry easier?
