I am looking at replaceing an oldish Trane thermostat that has been destroyed. This should be a fairly simple operation, but the unit doesn't go by the normal wiring codes. All I have are numbers 1-7, and they didn't go by color codes either(orange is 24v hot?) Can anybody tell me what the numbers go to so that I can tranfer them into the standard RH, RC, W, G...etc? I've looked everywhere for a schematic and all I could find was a Lennox product sheet.
Tstat is a Trane baysens0119a
Unit is a Trane ych1b0b3h0dd
Lennox part number 75H20 (seems to same exact tstat)

Thanks in advance, any help is much appreciated!

The other guy is absolutly right about buying a t-stat( Trane t-stat) to fix your problem. The microprocessor will not recognize any other zone sensor( t-stat) unless it is a 2005 ac unit

What you have is a progammable "electronic" zone sensor. It is not a thermostat and probably operates on 5V DC not 24 VAC. You need a Trane replacement or may wipe out some expensive components.
