If brown is not used then what I put earlyer should work just fine for you. Also make sure you read the installer setup and get it entered correctly

Put in a small piece of wire. Rc to rh probably already has a brass jumper in it

The fan still isn't working. The unit comes on but it won't blow. Any ideas? I've put it on fan on instead of auto and nothing.

If you can't make a jumper wire just move the red wire from rh to rc. That will give you cooling but no heat. Will the blower work if you turn the fan switch to on at the thermostat?Turn off all power going to the system first this will keep you from blowing a transformer.

Do you remember what colors were connected to what letters on the original thermostat? If not, you may have to peek inside the fan coil unit to see what wires are used for each function. Red, yellow, white, green, and orange are almost always universal, but black, blue, and brown (if used) are a little more subjective to the installer. Does the indoor blower come on if you jumper red and green at the thermostat?
