ON my system, and I forgot to mention it, there is no outdoor thermostat that I know of. Inside the air handler there is w1, w2, and w3 in which w2 and w3 are tied together.
I saw the section you are referring to about ODT-A and ODT-B which as far as I know I don't have either one. THey refer to an external unit for the ODT and I do not have that. I will do some more research on that and see what I can come up with.
