Trane XV95 / 802 Wired Correctly?

So after some discussion over in the humidifier forum, I learned a jumper trick with my 802 (TCONT802AS32DAA) Thermostat to enable a red led when the second stage was engaged. Only problem is, I installed the jumper, ramped the heat up to engage the second stage (and could hear it step up), but no light. This leads me to question if everything was wired correctly by my installers (who were aweful, so I wouldn't be surprised if its wrong).

The furnace is a Trane XV95 Variable Speed 100,000 BTU 2-stage unit. A 3.5 TON XR13 Trane Condenser unit is also installed, as well as Clean Effects, and the TCONT 802 Series T-Stat (listed above).

Here are some pictures of the current connections, taken last night while the second stage was on, and the jumper was installed:

In the pic of the connections at the furnace board, the large brown wire on the left comes down from the t-stat, the grey wire goes out to the clean effects, and the brown wire on the right with the red/white wires goes out to the A/C condenser.

I added the red jumper on the T-stat from Y2-F, and the black jumper on the furnace board form Y-O, based on advice from this forum.

Does the rest look correct? I can send any other pictures required, or provide any other info necessary.

Thanks!!

The stat jumper should be from W2 to F for light operation.

Thanks for the reply! I corrected the jumper, and the light now works!

Everything else look ok? Is the black jumper in the correct location for Comfort-R? Perhaps I should take a shot of the jumpers too so you guys can confirm those are correct? Just want to make sure the system is optimized for peak setup and performance! Thanks again!

just give me the actual model number. XV95 is a product line. The model number is inside the furnace on the side of the cabinet by the burner box.

Thanks for your help!

Did you move dip switch 5 and 6 to ON?

Are you using a humidistat between R and BK with the BK jumper cut?

I've never messed with the dip switches, they are still set to whatever they were at when installed. I just checked them and they are as follows: 1-on, 2-off, 3-off, 4-off, 5-on, 6-on, 7-on, 8-off. No humidifier yet, so no humidistat. Not sure which bk jumper your referring to cutting, is that only done when a humidifier is installed?

I do have a/c, the coil is model te35648c210b2505ap, condenser model 4ttr3042 a1000a.

I also have clean effects.

Thanks for the help!

I was asking about the BK jumper and humidistat (used for dehumidification with AC) because the y to o jumper you have installed is not necessary unless you are using the aforementioned setup.

Ok, so what should I do to correct? Doesn't the 802 have a built in humidistat? Someone told me installing the y to o jumper would enable comfort-r profiles. I'm confused...

Remove the Jumper and comfort -R profiles will work... The 803 enables "dehumidification" by simply allowing the thermostat to overshoot the cooling setpoint by 2-3F. The tcont 802 does not even sense humidity. For control of dehumidification you would need to add a humidistat or a higher end control such as the Vision PRO IAQ or Prestige (IAQ version if you don't have enough wires present at the thermostat) Honeywell has some great products coming out soon. I'm anxious to see some pricing. (just had a meeting with a HW rep today). BTW, HW makes the tcont series thermostats for Trane.
