So, the other day I decided to change my thermostat from a 5 day programmable thermostat (installed in 91) to an energy saver 7 day. I know if it ain't broke... don't fix it.

Well, the one I purchased said that it replaced 98% of all thermostats. I read the directions twice and did not see anything that would not be compatible with my system. Apparently, I must have fallen into the 2% category (Possibly because of the auxilliary heat, which I guess it can't be used with)...

Anyway, I removed the thermostat cover, made a note of all the wires (easy enough as they were colored coded White - W, Blue - B, Yellow - Y etc) and changed out the thermostat.

The unit I purchased had a touchscreen, which I learned did not work correctly (as in if you pressed the home key nothing happened, if you pressed the up arrow, it would not move etc.) Went to the store, purchased a new one. When I left, the air was on, but did not seem to blow that cold. Thought it was because it needed time to "warm up".

Came home with the new thermostat and noticed the air was not working at all. Installed new thermostat. Nothing.

Took new one off, replaced it with the original thermostat (which I was replacing). That one no longer works.

The original did not use batteries. When I flipped the power on, it use to light up. However, when I put it back on this last time, it no longer turns on (and yes I flipped the fuse box in the on position).

Does anyone know what I did wrong?

Could it be the motor or the capacitor? Maybe a blown fuse.

I know that I should call someone, but if it is a $50 part, I would prefer not to spend a fortune.

Of course, wouldn't you know I live in Florida and had to chose the month of July to change this. It is hotter in the house than outside.

Any advice you give would be greatly appreciated.

Thanks,

T. Johnson

Trane's B is common. Every other brand calls it common C.

You created a short when you wired old B to new B.

If you are using O, you have a heat pump.


An example of a Trane multistage heat pump stat...


Replace your low voltage fuse.
Trane fancoils...


Most fancoils...


Low voltage resets are great if you have one.


This stat is not compatible with multistage heat pumps...


This one is compatible with multistage heat pumps...
170 = 7
190 = 0
240 = 9

"Tip of the Day" Remember to remove power first.

Thank you for the information. I appreciate that you were so quick to get back to me and that all of the information was very helpful... and easy enough for me to understand :). I am picking up the fuse from Grainger on Monday.

Thanks again.
