I tried calling Trane and they told me to contact my A/C installer. When I
called my A/C installer, they said that they couldn't find any documentation
to do this. So with a year of trial and error, I finally figured it out:

1. Hold the "Information i", "Increase", and "Decrease" buttons at the same
time until all display segments appear.

2. Wait about 3 seconds and you'll then see two sets of numbers. The first
is like some kind of configuration option and the second number is the value.

3. Use the Time Up and Time Down keys to scroll through configuration options.

4. Use the Increase and Decrease buttons to change the values.

5. Press "Run Program" to exit.

Here's the few options I have figured out (feel free to add others if you
know of any):

30: Swing setting; seems to go as low as 3 degrees but the unit only handles
as low as 4 degrees

34: highest heating temperature

35: lowest cooling temperature

37: Adjusts the difference in the displayed temperature and the actual room
temperature

14: 0 -> Fahrenheit, 1 -> Celsius

12: This one was a little confusing. It seems to control the auto-changeover
mode. 0 and 2 seem to be auto-changeover (with 2 being more strict about
it). 1 is manual changeover.

13: If set to 0, the unit will start running before the actual programmed
temperature such that when the time does arrive, the temperature is correct.
If set to 1, the unit will start running to meet the programmed
temperature when the time actually arrives.

42: 0 -> 7-day programming, 1 -> 24 hour programming, 2 -> programming off

It don't mean a thang, if it ain't got that swing.

Get back to us in another year, let us know what else you've
learned about your thermostat.

From the manual that you are not allowed to have:
30 = Deadband
Default: 3 Heating and cooling setpoints can be set no closer than 3°F
(1.5°C)

4 thru 10
Heating and cooling setpoints can be set no closer than the chosen value:
4-4°F (2°C)
5-5°F (2.5°C)
6-6°F (3°C)
7-7°F (3.5°C)
8-8°F (4°C)
9-9°F (4.5°C)
10-10°F (5°C)

You are of course aware that "playing" with certain settings can result in
you damaging your system. A question: What did you leave # 33 and #37 at
after messing with it?

Maybe if you checked with the manufacturer of the thermostat.....
<Honeywell>. But then if your tech was *competent*, he would know that.

That thermostat is very similar to this one produced by the same
manufacturer for Trane:
