Been working at a new place with trane voyagers, mostly YCH300B4HOHB models. First time I've come across this...all the units use BAYSENS017B remote zone sensor. The two wires from the remote sensor connects to an ajustable zone sensor module (BAYSENS008B) in the roof top's electrical compartment. This has been the facility's way of keeping employees from tampering with the setpoints...dumb, I know.

I've been told that the outdoor adjustable zone sensor has to have a resistor or something, that has to be cut so that the two zones sensors don't fight each other, and only read the remote sensor's zone temp.

Has anyone else seen or heard of such a setup?
