How to wire digital thermostat?

I'm replacing my analog intertherm thermostat to a hunter digital. Wiring codes do not match up. Intertherm wires coded as G, O, Y, E, X, R. Hunter coded as Y1, W/B, Y/O, RH, RC, G. I have a Trane unit.How to wire digital thermostat?Go to the furnace itself and see what colored wires are connected to which terminals on the board.



These will be the only wires you are concerned about, and you want to verify the labels of the terminals on the furnace itself.



Besides, you want to confirm that the colored wires are in their typical use.



I believe, can't be positive, that the Trane board will match the Hunter terminal codes.



Here is a handy link for t-stat wiring and codes: http://www.toad.net/~jsmeenen/wiring.htm



G'luck!



On edit: If you can provide the terminal names and colors of the wire connections to the Trane board, I (or another) can tell you which terminals on the t-stat to connect.



A model number of both the Trane and Hunter unit would be helpful also.

Yep. That would be a 'deal killer'. LOL!
