I have a customer who has asked me to look at his control system. I am primarily a Delta tech. What he has is a Honeywell XL80 system.
Does this require a propriatary software to configure? It seems to me that the IP that the OAT sensor is tied into is bad. My 20Kohm sensor checks out alright but is way off on the controller.

What I am looking to be able to do is move the sensor from IP 5 to IP6 to see if it reads properly.

Does anyone have any info on these? Name:  IMG-20121023-00015.jpg
