I am attempting to replace my current thermostat with a Trane XL824. After reviewing the wiring instructions I am having a hard time determining exactly how to wire this thing. This thermostat seems to have more than one option for each of the wires so I'm a bit confused. I have attached a picture of the old thermostat with its current wiring and a picture of the new thermostat's terminal connections. There are literally 15 pages of optional wiring diagrams in the manual just for a heat pump, which we unfortunately have, each covering different configurations, various air handlers, etc.
 
Leave Rh to RC jumper in place. connect red wire to RH or RC, yellow wire to Y1, orange wire to O, green to G, Black to C, and white wire to W1. Then read the install manual to set up the thermostat for proper operation.
I shut off furnace but still making loud noise.
What kind of noise? And please stop eating these beans!

Need to increase indoor temps to 88 -95F. Got a nasty VOC issue and I need to do a bake out. I'm in central Texas with temp in low to high 90s with dew points between 69 -73.
Want to get the indoor temps up before using out side ventilation to keep indoor RH<60.
Question: Can I run the heater of my heat pump when out door temps are in the low to mid 90sF. My starting indoor temp will be in the low 70s at about 45 - 50 RH. I'm concerned about damaging my heat pump.
If you can run heat strips without running compressor there should be no harm done. Otherwise, don't heat in hot weather with heat pump. In hot weather, if you need to heat house up but keep humidity low, turn off a/c, leave windows closed, and rent a beefy dehumidifier used to dry out structures after flooding events. The building will heat the house due to solar gain from roof, windows, and walls.
Should condensate pump have water in the lines?
Yes, it should. In some older models, it must.
Should I get a window unit for room above garage?
Well, try to contact me first on this page.
We have a ceiling register that is over our bed and at times we want to completely close this while we sleep. However, this is a standard home depot register and when it is closed it whistles loudly (when closed, you can visually see cracks so you know that the air is going to leak through, similar to all the other registers that came with the house). Are there any registers that completely seal off the air flow? Simply get a magnetic vent cover to block a metal heat register. You can find these at hardware and other assorted stores. Before purchasing, check the size, quantity and thickness or other features. If it fits the register precisely, simply align it and slap it in place, over top the vent. Usually it will require trimming with scissors. Unscrew the register, place it on top of the magnetic material, and trace around it for a cut guide.
