I guess what I was trying to say is how would I install a new thermostat mounted on the wall and run the branch and air pressureline to the thermostat. I'm not sure how to hook it up to the main supply line.


I will check out the other sites that you and labman suggested.

Thanks

If you get back with more details perhaps someome here can help.

Are there any other stats in the building that you can look at and see how it was done before?
