I have a Braeburn 3200 thermostat which I would like to try as a
replacement for my existing Carrier/Totaline unit. The Braeburn stat
has multi-colored LED status indicators and an "L" (system status)
terminal, while my old stat does not have this feature (nor does it
have an "L" or "X" terminal). Can anyone tell me how to use the "L"
terminal on the Braeburn stat -- or should I just leave this terminal
unconnected, and possibly do without the LED status indicators? My
system is a Carrier heat pump with electric aux. heat (2H/1C). Thanks
for any useful info.

The status LEDs are optional. In some installations I have wired the L
terminal to W2 / E so that the customer can see when the strips are on.

Thank you, Travis, for the helpful info. Would I be correct to assume
then that a common leg of all 3 LEDs is probably tied to the 24v
return, and that the the application of 24 volts (possibly thru a
current limiting resistor) to the other side of each LED will turn it
"on"? [A schematic of the thermostat sure would be nice ;-)]

Replace deadspam with yahoo to reply.

Whats odd here, is that if you have an X and an L terminal, the L is
normally the trouble indicator, the X is normally the same as a C.
THATS the way most Honeywell stats are wired.

Looking at the 3200 wiring, you have a R, Y, Y2, W2, E, G, O, B, L, and C
terminal.

Its a very basic stat. Nothing fancy about it.

The LEDs are wired so that they come on if you have a C leg wired, and the C
is nothing but the systems common to transformer. If your original wiring
didnt have one, you will need to get a new stat wire pulled with enough
wires to have one and it simply is nothing but the opposite side of the
transformer that the R line is pulled off off.
The L line is your trouble indicator. If your old unit had this, then use it
here.
I notice that they claim B is a common on their wiring, but not on a heat
pump...at least not a newer one..that would be the RV and if you have wired
it when it needs to be on an O line, then its not going to work.
