Hello, I am Luke , here to help you with that.

Do you have the make and model of new t-stat? not furnace
I have to leave soon can we wrap this up ASAP
Standard wiring is......White wire goes to W, red wire to R, black wire to C, yellow wire to Y, green wire to G
If your wires are not consistent with standard wiring colors, refer to the t-stat wire attached to the oil burner control in your furnace then hook up t-stat with the colors you have.

So youre saying that out of the wall at t-stat you have just black and white. thats it?

OK 10 wires will require more information from you/
what else do you have for equipment?
If you have old t-stat and if possible with a clear picture of where all the wire go to it would help us alot.
I will be back a little later to continue with you.
Hello my name is Billy.
First of all here is the manual for your unit
Rheem ROBC Manual
Now You have an oil burner...and you are discussing a fan center relay in the furnace. This is not commonly original and is added if ac is installed.
Are you installing a fan center? Or just a thermostat?
Also the furnace uses just T and T terminals for the heat..but depending on how the unit is wired you could have what is called a 2 transformer system...
This would mean at the fan center transformer you would use R,Y,G and C...then 2 wire would run into the furnace and install on the oil primary on (2) T terminals.
I need to know where the wires on T and T currently go...then we can determine if you have a 2 transformer unit
On the back should be 2 Black wires..one for transformer and one for fan power.
Both of these blacks tie into 115v power.
Red wire goes to heat speed blower
brown wire goes to high speed blower
white to neutral.
To decipher thermostat wires I would need to know what terminals has what color is attached to it.
