I just started a new job, they have a trane rtu with the ucb. The unit is not running. The guy I replaced had a t-stat hooked up but it was for a 24volt. He had replaced the original stat which was a zone sensor baysenoo8 five wire. I found the sensor in his shop. It isn't working. I can jump the low v. term. for the test proceedor and unit will run and cool. But will eventually stop. Question..does it have to be the baysen0008?? i understand they are obsolete.
