    Confused BAYSENS009B, Need help changing to BAYSENS019

    Hello again folks!

    I bought the BAYSENS019 dig. pro. zone sensor. I am taking out the BAYSENS009b manual sensor. I am having trouble re-wiring the new zone, this being my first time. I think I have an idea, but would rather be for sure from you guys. This sensor ran me 400.00. Here is some info that may help...

    old wiring for baysens009b

    term 1 (ZTEMP) ----red
    term2(signal common)----yellow
    term3 (CSP)---green
    term4(mode)----white
    term5(HSP)---blue

    term6(led common)---orange
    term7(Heat)----brown

    Here are the terminals for the new BAYSENS019

    S2 (remote sensor input)
    S1 (Remote sensor input)
    14 24 vac input
    12 communication
    11 common*
    10 service status(ucm input)
    9 system status(on/off input)
    8 cool status(ucm input)
    7 Heat Status(ucm input)
    A3 Aux relay (closed unoccupied)
    A2 Aux relay (common)
    A1 Aux relay (closed occupied)

    I would appreciate your help.
    Thanks

    look on page 11 of IOM

    looks like you're gonna make a trip to roof to relocate some wires

    what mod is this going on

    thanks dandy..

    this is going on a Trane WCD090C300BC...I haven't been on the roof today, but I do know there not a scematic on the inside panel anymore.

    I figured I could use the terminal board numbers because the manual zone sensor I'm replacing is hooked up right. Sounds like I don't wanna trace wires huh..

    pg 11 tells you what term to hook up

    the same terminal connection at 019 and unit

    that's what I'm seeing
