TRANE control wiring

[Mikeylikesit]

can anyone tell me which terminal strip # corresponds with COOL 2 ?


TRANE YCD120B3L0DA with a BAYSENS010B zone sensor.


my first stage cooling is shot, leaking at the cond. coils. I want to jump Y1 and Y2 together, temporarily, to give the space cooling. However, yea for Trane, they abolished the Y1, W, G, etc. wiring conventions....

thank you in advance!

Is the BAYSENS010B the one with the setpoint slider bars? If it is i dont believe that type of sensors uses y1, y2 etc.. It sends a cool output to the unit. If you dont see Y1, Y2 right next to the terminal block that the BAYSENS is hooked too i dont know how you would do it. I dont have much experience with them tho.

thanks anyway, got her working........removed control wires to contactor circuit #2, tape them off. Remove control wires from Contactor #1, place on contactor #2. Splice off low pressure switch on circuit #1......it's empty, remember?

Unit now runs on Circuit#2 in the Cool 1 mode...........no more Cool 2!

this should get me thru the week, next week, cond. coils R/R.
