    The Honeywell vision pro is AC voltage I think......

    What kind or RTU's are they Trane?

    You can wire Voyagers and Precedants for either voltages DC or AC.

    Not too much info to go on, so if I'm directing you in the wrong direction I apologize.

    Were the thermostats that you removed Trane's because if they were your Honeywell T-stat will not work with the voyager controls unless you purchase a TCI card. I am not sure what that stands for but without it you wont be able to use a non trane stat or sensor. It is a little card that is added to the circuit board.

    careful...acronyms can get tricky . TCI stands for Tracer Communication Interface...it is a different board. the CTI board is the one he would need (depending on unit configuration). CTI is Conventional Thermostat Interface. we need more info, like the entire model and serial number to see what was originally ordered. the H/W model number of the t-stat and the model number off of the old t-stat would be very helpful. more acronyms in our industry would also be helpful .

    good luck.

    I hate proprietary thermostat schemes.

    Their only purpose is to lock the customer into OEM service.

    It is not a proprietary thermostat scheme, it is because in the real world of commercial installations there is a thing called BAS. The trane unit simply offers a way to do BAS and non-BAS systems easily, with a board change.

    Not to be rude, but you already started one thread on this subject and received some good advice on the subject. Why not stick with it?
